Wastewater treatment and removal of pollutants by phytoremediation, remain a major concern of the 21th century. This study is focused on the phytoremediation study in Philippine setting, specifically in one of the tributaries of Pasig river-the Estero de San Miguel. It determined the pH, Ammonia and Phosphorous before, 7th and 14th day of phytoremediation with the use of A. pinnata and E. crassipes. Twelve improvised water ponds/troughs, 3 ponds per treatment were used for 14 days. T- control (only wastewater), T1 for A. pinnata + wastewater, T2 for E. crassipes + wastewater and T3 for A. pinnata E. crassipes + wastewater. Potential hydrogen, Ammonia-N mg/L, phosphorous mg/L were analyzed before, on the 7th and 14th day of the study. Data gathered was analyzed using ANOVA and Fisher Least Significant Difference test as post hoc test. Result revealed that T1 (A. pinnata) lowered the pH and ammonia-N (mg/L) of wastewaters from Estero de San Miguel. T3 (combination of A. pinnata + E. crassipes) has significantly lowered the Phosphorous level of the wastewaters. Thus both aquatic macrophytes can be used as phytoremediation agents in the said Estero.

Abstract The physico-chemical and bacteriological quality was evaluated in wastewater samples before and after treatment by microalgae enrichment. Three types of wastewater samples – raw water, inlet water and outlet water – were taken directly from the wastewater treatment plant and subjected to microalgae enrichment culture during two months. The main objective of this work was to apply a phytoremediation process based on the use of compulsory microalgae treatment of wastewater from treatment plants compared to other secondary treatments. The biomass of microalgae was extracted to determine the concentrations of phenolic compounds, sugars and especially lipids, which can be subsequently transformed into biodiesel. As a result, the pH showed a significant increase after microalgae proliferation, with values ranging from 9.94 to 10.36. Bacterial community analysis before and after microalgae culture showed a clear shift in biomass content. The total coliform (TC) and the fecal coliform (FC) contents decreased after microalgae enrichment. In addition, the fecal streptococci (FS) and Pseudomonas present in the different wastewater samples completely disappeared after treatment. The applied phytoremediation process showed a drop until the disappearance of the contagious microbes – which present a very serious health risk – due to the release of the quinic acid. The quinic acid observed in the treated waters exceeded the content of 464.328 mg/L. This phenolic compound naturally produced during the process demonstrated a very effective antimicrobial power. However, a significant increment of 100% of phenol compound removal was observed after microalgae enrichment. The lipid content in the various studied samples appeared after microalgae culture. In addition, the heavy metals, namely cadmium and chromium, were completely eliminated after the treatment. Several socioeconomic advantages can be achieved by the use of this process, notably the environmental advantages of bioenergetics and economic and social benefits of the non-expensive valorization of wastewaters for irrigation.

Full textAbstract:
Plant macrophytes in wastewater treatment systems are important for providing various ecological and environmental benefits, e.g. detoxification and removal of toxic heavy metals. In this study, phytoremediation of four heavy metals (Cd, Cu, Pb and Zn) by water hyacinth (E. crassipes) in sewage wastewater stabilization ponds under humid lowland tropical climatic conditions in Papua New Guinea was studied using a purposive design and grab sampling technique. The wastewater and plant samples collected were analysed for the heavy metals. In almost all cases, an increasing concentration of heavy metals exceeding the standard (FAO and WHO) minimum permissible levels was measured in both the wastewater and the leaves. The general trend in concentration of the effluent pond was such that Pb>Zn>Cu>Cd in the wastewater and Zn>Cu>Pb>Cd in the leaves, respectively. The high variability in heavy metal concentration ranged from between 57-99% in the wastewaters and 61-63% in the leaves, respectively. The availability in the effluent wastewater probably results from decomposition of plant matters and release of the heavy metals bioaccumulated back into the wastewater. A management option to address high availability and mobility in the wastewater is to remove the plant macrophytes well before senescence and turnover of plant matters.

Full textAbstract:
Organic matter, nutrients, and chemicals are some of the waste materials found in most domestic wastewaters. The purpose of this research was to evaluate the potentials of Pistia stratiotes, Salvinia molesta, and Eichhornia crassipes aquatic weed plants in the tertiary treatment of secondary domestic wastewater using hydroponic systems. Physicochemical analysis that considered turbidity, phosphate, ammoniacal nitrogen, and nitrate was conducted on the wastewater samples at different retention times of 6, 12, and 24 h for 14 days. The best performance was observed for a 24 h retention treatment system, with up to 91% (P. stratiotes), 94% (S. molesta), and 89.3% (E. crassipes) reduction for turbidity; 81.2% (P. stratiotes), 82.7% (S. molesta), and 88.5% (E. crassipes) for phosphate reduction; 88.66% (P. stratiotes), 90.47% (S. molesta), and 89.11% (E. crassipes) for ammoniacal nitrogen reduction; 83.6% (P. stratiotes), 92.1% (S. molesta) and 93% (E. crassipes) for nitrate reduction. Hence, the application of hydroponic systems in cultivation of the macrophytes proved to be effective in the phytoremediation process by removing the residual nutrients present in the treated secondary domestic wastewater. Additionally, this method can be used for the cultivation of plant-based biomass and other non-edible useful crops using the free nutrients content of the wastewater before its discharge into the natural environment.

Full textAbstract:
Microalgae are photosynthetic microorganisms and are considered excellent candidates for a wide range of biotechnological applications, including the removal of nutrients from urban wastewaters, which they can recover and convert into biomass. Microalgae-based systems can be integrated into conventional urban wastewater treatment plants (WW-TP) to improve the water depuration process. However, microalgal strain selection represents a crucial step for effective phytoremediation. In this work, a microalga isolated from the effluent derived from the thickening stage of waste sludge of an urban WW-TP was selected and tested to highlight its potential for nutrient removal. Ammonium and phosphate abatements by microalgae were evaluated using both the effluent and a synthetic medium in a comparative approach. Parallelly, the isolate was characterized in terms of growth capability, morphology, photosynthetic pigment content and photosystem II maximum quantum yield. The isolated microalga showed surprisingly high biomass yield and removal efficiency of both ammonium and phosphate ions from the effluent but not from the synthetic medium. This suggests its clear preference to grow in the effluent, linked to the overall characteristics of this matrix. Moreover, biomass from microalgae cultivated in wastewater was enriched in photosynthetic pigments, polyphosphates, proteins and starch, but not lipids, suggesting its possible use as a biofertilizer.

The present issue embraces a broad spectrum of studies focused on applied or potentially applied aspects of microbiology and biotechnology. The papers reflect current scientific and technological investigations, which were performed in Latvia, Lithuania, Estonia, Sweden. Most of them are interdisciplinary, i.e., the expertises in microbiology, biochemistry, chemistry, veterinary, physics, engineering and other fields were applied. Probiotic lactic acid bacteria were tested for their antagonistic activity against mastitis causing bacteria. Three papers are focused on optimization of fermentation processes, using maize silage and acid whey in anaerobic processes, barley and pea fibers as well as lupine seeds for obtaining biologically active compounds. Wastewater treatment processes are represented by studies on the use of pink bark as a sorbent of nitroaromatic compounds; as well as biodegradation of phenols in pharmaceutical wastewaters and combination of nitrification and phosphorous accumulation processes. Newly developed inorganic carriers for solid state and submerged fermentations were tested, e.g., ceramic and alkali-activated beads. The review paper covers basic processes of phytoremediation with special emphasis on rhizoremediation and plant-microbe interactions in a plant–assisted biodegradation in soils and treatment wetlands. Methodological aspects were discussed, in particular, the use of Fourier transform infrared spectroscopy in monitoring the sorption and degradation products in wastewaters. A new yeast based test system for rapid evaluation of the effects of various compounds on eukaryotic cells was suggested. Hopefully, you will find the papers included in this issue, interesting and useful.

Full textAbstract:
The release of inadequately treated urban wastewater is the main cause of environmental pollution of aquatic ecosystems. Among efficient and environmentally friendly technologies to improve the remediation process, those based on microalgae represent an attractive alternative due to the potential of microalgae to remove nitrogen (N) and phosphorus (P) from wastewaters. In this work, microalgae were isolated from the centrate stream of an urban wastewater treatment plant and a native Chlorella-like species was selected for studies on nutrient removal from centrate streams. Comparative experiments were set up using 100% centrate and BG11 synthetic medium, modified with the same N and P as the effluent. Since microalgal growth in 100% effluent was inhibited, cultivation of microalgae was performed by mixing tap-freshwater with centrate at increasing percentages (50%, 60%, 70%, and 80%). While algal biomass and nutrient removal was little affected by the differently diluted effluent, morpho-physiological parameters (FV/FM ratio, carotenoids, chloroplast ultrastructure) showed that cell stress increased with increasing amounts of centrate. However, the production of an algal biomass enriched in carotenoids and P, together with N and P abatement in the effluent, supports promising microalgae applications that combine centrate remediation with the production of compounds of biotechnological interest; for example, for organic agriculture.

Full textAbstract:
Phytoremediation is an environmentally friendly and sustainable alternative for treatment of nitrogen-enriched wastewaters. In this study, Ta-khian (Hopea odorata) and Lagos mahogany (Khaya ivorensis), two tropical timber plants, were investigated for their performances in treatment of urea manufacturing factory effluent with high nitrogen (N) content. Plant seedlings received four concentrations of N (190, 240, 290 and 340 mg/L N) in laboratory-scale constructed wetlands every 4 days for a duration of 8 weeks. The solution volumes supplied to each container, amount of N recovered by plants and plant growth characteristics were measured throughout the experiment. Results showed that Ta-khian plants were highly effective at reducing N concentration and volume of water. A maximum of 63.05% N recovery was obtained by Ta-khian plants grown in 290 mg/L N, which was assimilated in the chlorophyll molecule structure and shoot biomass. Significant positive correlations have been shown between N recovery percentages and plant growth parameters. Ta-Khian plants can be applied as suitable phytoremediators for mitigating N pollution in water sources.

Full textAbstract:
The continuous expansion in the textile industry results in high loads of coloured wastewaters that heavily pollute the limited freshwater sources. Therefore, a wide array of treatment methods has been used to remediate water/wastewater from dyes. One common practice is the use of plants to degrade, absorb, metabolise, and detoxify different types of pollutants, including dyes. This study employs sweet basil (Ocimum basilicum) as a phytoremediation model herb to remove different concentrations (5–25 mg/L) of methylene blue (MB) dye from synthetic water, taking into account the effects of the MB dye concentration (5–25 mg/L) and contact time (up to 10 days). The results showed that the ability of Ocimum basilicum to absorb MB dye decreased with the increase of the MB dye concentration and increased with the increase of the contact time. The best removal of the MB dye was 93% when the concentration of the MB dye was 25 mg/L and the contact time was 10 days. Additionally, it was noticed that the relative growth rate (RGR) of the herbs was adversely influenced by increasing MB dye concentrations and that the best RGR value was 2.2 g/day when the MB dye concentration was 5 mg/L.

Full textAbstract:
The purpose of the study was to review the most recent findings related to lead toxicity for plants, animals and humans. It is stated that the highest potential belongs to biological techniques and the most up-to-date lead phytoremediation technologies. Results and discussion. Lead is one of the most toxic heavy metals which frequently occurs in the environment. Various quantitative indices are used to assess lead toxicity at trophic levels of a food chain, including the levels of lead absorption by plants. Hyperaccumulating plants can accumulate more than 1000 mg/kg of the metal. Higher lead concentrations are connected with fruit plants. Lead transport in animals is done through the blood circulatory system, whereby bones are the main lead absorbers (~ 90%), where lead replace calcium and reduces the bone mineral density. Lead poisoning in humans most frequently results from peroral intake and absorption through the gastrointestinal tract. The main process of lead transport from the gastrointestinal tract to various body tissues is conducted via erythrocytes, where lead binds to hemoglobin. The half-life of lead in blood and soft tissues has been estimated as 35 and 40 days, respectively. Lead may stay in the bones up to 30 years; its concentration rate in the teeth and bones increases with age. Over 95% of lead deposit in the skeleton represent an insoluble phosphate. The biological half-life of lead in children is significantly larger than in adults. The total lead load on skeleton makes 80-95% in adults and around 73% in children. Lead toxicity primarily targets the human central nervous system, and child exposure to high amounts of lead from the environment, particularly in the case of anemia, entails low intelligence and movement disorders. Mothers can transmit lead to fetus or infants during breast-feeding. There are various processes that seek to reduce the overall lead concentration and accumulation in the food chain. Out of those, the most effective are biological techniques of lead remediation from contaminated resources. They include phytoremediation and microbiological treatment. The first option reduces lead mobility in the root zone of plants through complex formation. The second option reduces lead availability in the environment via employing local microorganisms. Both options are a natural, safe, efficient, and environmentally friendly technology which implies cost-effective operation and represents no threat to the environment and health. However, a high potential is detected in biotechnological and genetic approaches, such as genomics, metagenomics, metabolomics, proteomics, transcriptomics, nanoparticles, and isotope probing. These are the most up-to-date technologies for lead phytoremediation. The use of omics approaches implies identifying candidate genes for an efficient lead removal, diverse phylogenetic research into the sequence of genes and proteins that control lead bioremediation and genetically modified plants cultivation via transgenesis, which are able to restore various wastewaters, contaminated lands, and can be beneficial for practical application in bioremediation. Conclusion. The most recent research and development in the field of nanosciences provide access to even more efficient and stable approaches to remediation that are being successfully applied in cleaning soils, deposits, solid waste, and wastewaters

The growth of the textile industry, including the Sasirangan textile industry, is increasing yearly, producing large amounts of liquid waste. Generally, this wastewater is discharged into the environment without treatment, becoming a source of environmental pollution. Therefore, it is crucial to reduce these pollutants. Various methods, not only physical and chemical but also biological methods, are available to remediate wastewater. Phytoremediation has provided an economical, environmentally friendly, and aesthetic solution to remediate wastewater. This study aimed to utilize the Water Hyacinth plant as a phytoremediator and determine its effect in reducing Total Suspended Solid and colors in the liquid waste of the Sasirangan textile industry. This research begins by preparing Water Hyacinth plants. Next, the characterization of Water Hyacinth roots using FTIR and SEM. Finaly, the acclimatization of water Hyacinth, followed by a phytoremediation process for 15 days. Based on the results of the characterization of Water Hyacinth roots with FTIR, it shows that Water Hyacinth roots contain functional groups O-H strain, C-H vibrations, C=O strain, C-H deformation, and C-O stretching. Observations with SEM showed that the roots of Water Hyacinth were extremely unstructured and had pores. However, it has cavities which are pores in cellulose. The significant decrease in Total Suspended Solid was at 9 days of phytoremediation, which was 54 mg/L (71.12% removal). The optimum color reduction within 9 days of phytoremediation was 81.5 PtCo (92.26% removal). The presence of these functional groups and pores, strengthened by the analysis of Total Suspended Solid and colors, showed that Water Hyacinth could reduce levels of Total Suspended Solids and colors in the Sasirangan textile wastewater.

It is noteworthy that ammoniacal nitrogen contamination in wastewater has reportedly posed a great threat to the environment. Although there are several conventional technologies being employed to remediate ammoniacal nitrogen contamination in wastewater, they are not sustainable and cost-effective. Along this line, the present study aims to highlight the significance of green chemistry characteristics of phytoremediation in nitrogen for wastewater treatment. Notably, ammoniacal nitrogen can be found in many types of sources and it brings harmful effects to the environment. Hence, the present study also reviews the phytoremediation of nitrogen and describes its green chemistry characteristics. Additionally, the different types of wastewater contaminants and their effects on phytoremediation and the phytoremediation consideration in wastewater treatment application and sustainable waste management of harvested aquatic macrophytes were reviewed. Finally, the present study explicates the future perspectives of phytoremediation. Based on the reviews, it can be concluded that green chemistry characteristics of phytoremediation in nitrogen have proved that it is sustainable and cost-effective in relation to other existing ammoniacal nitrogen remediation technologies. Therefore, it can be deduced that a cheaper and more environmental friendly ammoniacal nitrogen technology can be achieved with the utilization of phytoremediation in wastewater treatment.

Abstract Water spinach (Ipomoea aquatica Forsk.) has the ability to accumulate pollutants so that it can be useful for wastewater treatment processes. The purpose of this study was to determine the phytoremediation technique in hospital wastewater using kale in improving the quality of hospital wastewater and to determine the level of accumulation of Pb and Cr metals in plants. The study used a completely randomized design with four treatments, namely treatment 0 days (without treatment), 2 days, 4 days and 6 days. Parameters include the physical and chemical quality of the waste as well as the content of Pb and Cr in the waste and plants. To determine the effect of phytoremediation on the quality of household waste and metal content, ANOVA analysis and further testing with the BNT test level of 5% were used. Phytoremediation with kale was able to reduce the temperature of the waste on the 4th day of treatment and dissolved oxygen on the 4th treatment and increase the pH. The accumulation of Pb and Cr on each day is different. The highest accumulation of Pb and Cr occurred on day 6, namely 0.1587 mg/L for Pb metal and 0.2167 mg/L for Cr metal. Kale plants are very possible to be used in the phytoremediation process.

Laundry activities grow rapidly in Indonesia in the recent year, remaining the problem of environmental pollution because of the use of detergent. The purpose of the current study was to investigate the ability of sludge of drinking water treatment plant (DWTP) as adsorbent combined with phytoremediation system to remove chemical oxygen demand (COD), phosphate and surfactant in laundry wastewater. Batch and continuous blow studies were conducted on different variables such as adsorbent mass, contact time, and type of plant for phytoremediation system. The results of the current study show that adsorption combined phytoremediation system could remove COD, phosphate, and surfactant up to 77.5%, 54.3%, and 99.9%, respectively. Based on the results, it means that the adsorption combined phytoremediation system could be considered as an appropriate environmental technology for laundry wastewater treatment in the near future.

Abstract Wastewater is any water source that a human has used for domestic, agricultural, commercial, or industrial activity. Wastewater needs to be treated before being discharged into the environment to reduce contamination of water bodies. The wastewater treatment must follow the Environmental Quality (Sewage) Regulations, 2009. Rivers in Malaysia continue to suffer wastewater pollution from the inefficiency of treatment. Wastewater has been recognized as the significant cause of these issues. Many physical, chemical, and biological techniques have evolved for sewage treatment. It has been observed that biological procedures are advantageous, and one of these procedures that can be considered is phytoremediation. Thus, this study investigated the effectiveness of water hyacinths in treating wastewater, such as the effluent from the wastewater treatment plant, river, and pond in Pusat Asasi, UiTM Dengkil, Selangor, by phytoremediation. Different parameters of pH, suspended solids, phosphorus, ammonia-nitrogen, nitrite-nitrogen, nitrate-nitrogen, chemical oxygen demand and biological oxygen demand have been assessed. The research has been conducted with experimental works of 14 days. The laboratory works showed a significant reduction in most parameters after two weeks of phytoremediation.

Abstract Two demonstration wastewater treatment systems, i.e. a phytoremediation system and a membrane bioreactor (MBR) system, were studied for a six-month period from August 2016 to January 2017. The phytoremediation system consists of wetland cells implanted with diverse phytoremediation macrophyte species at NUST H-12 sector Islamabad, Pakistan, while the MBR system comprises primary clarifiers, membrane tanks and bio tanks that treat domestic wastewater through hybridization of biological and biomechanical techniques. The phytoremediation system receives domestic wastewater at the rate of 283 m3/d, and greater hydraulic efficiencies were achieved because of compartmentalization and higher aspect ratios, whereas the MBR system receives 50 m3/d. The present study was conducted to analyze and compare the correlation between water quality parameters of wastewater treatment systems and meteorological conditions. Statistically significant correlation was exhibited between eight water quality parameters (pH, EC, turbidity, dissolved oxygen, total suspended solids (TSS), chemical oxygen demand (COD), biological oxygen demand (BOD) and total coliforms (TC)) and meteorological factors (ambient temperature and relative humidity). Predominant species isolated and identified through polymerase chain reaction and 16S rRNA sequencing from wastewater of the phytoremediation system and sludge of the MBR system belong to the phylum Proteobacteria with relatively higher abundance of Enterobacter, Shigella, Escherichia and Salmonella genera.

Full textAbstract:
Phytoremediation is a technology that is based on the combined action of plants and their associated microbial communities to degrade, remove, transform, or immobilize toxic compounds located in soils, sediments, and more recently in polluted ground water and wastewater in treatment wetlands. Phytoremediation could be used to treat different types of contaminants including petroleum hydrocarbons, chlorinated solvents, pesticides, explosives, heavy metals and radionuclides in soil and water. The advantages of phytoremediation compared to conventional techniques are lower cost, low disruptiveness to the environment, public acceptance, and potentiality to remediate various pollutants. The use of plants in conjunction with plant associated bacteria (rhizosphere or endophytic) offers greater potential for bioremediation of organic compounds, and in some cases inorganic pollutants than using plants alone in bioremediation. The implementation of treatment wetlands for phytoremediation of wastewater or polluted water originating from various sources allows removing organic and inorganic pollutants from water in an environmentally friendly and economically feasible way. Presently, different processes of phytoremediation in treatment wetlands are less studied compared to phytoremediation of polluted soils. Further research is needed to advance the understanding of the pollutant removal mechanisms in treatment wetlands with vegetation, and how based on this information to improve treatment wetland design and operational parameters to achieve more efficient treatment processes. This review covers basic processes of phytoremediation with special emphasis on rhizoremediation and plant-microbe interactions in plant–assisted biodegradation in soil and treatment wetlands.

The efficiency of Eichhornia crassipes for treatment of raw kitchen wastewater was studied in the present research work. An artificial wetland of 30 liter capacity was created for phytoremediation of kitchen wastewater using Eichhornia crassipes. Kitchen wastewater samples were collected from hostel of an educational institute in India. Samples were characterized based on physical and chemical parameters such as pH, turbidity, total hardness, nitrate-nitrogen, ammonium-nitrogen, sulphate, dissolved oxygen, total organic carbon and total dissolved solid. The physico-chemical parameter of kitchen wastewater samples were analysed for durations of 0 (initial day), 4 and 8 days. After 8 days of retention period, it was observed that pH value increases from 6.25 to 6.63. However, percentage reduction for turbidity, total hardness, nitrate-nitrogen, ammonium-nitrogen, sulphate, dissolved oxygen, total organic carbon and total dissolved solid were found to be 74.71%, 50%, 78.75%, 60.28%, 25.31%, 33.33%, 15.38% and 69.97%, respectively. Hence water hyacinth (Eichhornia crassipes) is found efficient and easy to handle and it can be used for low cost phytoremediation technique.

Full textAbstract:
The increase of the global population and the requirement of food production and agricultural development, combined with a lack of water resources, have led to human attention being drawn to unconventional water sources, including saline water and wastewater. Most unconventional water treatment methods are not cost-effective; however, researchers have become interested in the phytoremediation method due to its cost-efficient and eco-friendly removal of many pollutants in recent years. Research showed that due to its unique characteristics, vetiver grass can be useful in phytoremediation. In the current review, research on vetiver-based phytoremediation of unconventional water, especially wastewater, was reviewed. The vetiver-reduced contaminants in wastewater can be related to the interactions between (1) the root-released oxygen into the rhizosphere; (2) the root-based uptake of nutrients from the wastewater; (3) the existence of an appropriate surface area for the attached microbial growth; as well as (4) the root-exuded organic carbon.

This study was aimed to determine the effect of electro-assisted and oxygen injection system to improve the effectiveness of the copper and iron removal in wastewater by phytoremediation system. The electro-assisted phytoremediation (EAPR) system was run with Vetiver grass (Vetiveira zizanioides L) as accumulator plant and 2 V of constant DC power supply using 2D cathode-pot electrode and air diffuser configuration on the aeration by air flow rate of 10 L/min. The effectiveness of phytoremediation, phyto-aeration,and phytoremediation on the wastewater treatment was compared and evaluated by measuring the decreasing of heavy metal concentration in the wastewater and accumulated inthe plant. Plant stress was monitored by the observation of phytomorphology changed and measurement chlorophyll content using UV-Vis Spectroscopy after the acetone extraction and heavy metal concentration was measured by Flame-Atomic Absorption Spectroscopy (Flame-AAS). The results showed that the decreasing of Cu and Fe concentration in the wastewater as much as 86.5% and 99,3%, higher than that phyto-aeration (82.35% and 99.20%) and phytoremediation (15.0% and 56.0%). The uptake profiles of heavy metal by plant indicated the enhancement ability of electro-assisted and aeration system to the phytoremediation has different results. For example in the root part, the heavy metal absorption occurred most often as following in phytoremediation>phyto-aeration>EAPR-aeration. Contrary results show in the EAPR-aeration system that the metal concentration quiet high translocation from root to shoot part by enhancement of electro-assisted and aeration system. High chlorophyll content and chlorophyll ratio in the plant under the EAPR-aeration system shows higher tolerance of the plant to the heavy metal concentration.

Heavy metals accumulation from industrial wastewater even at low concentrations can cause long term cumulative health effects. To overcome this problem, phytoremediation is an alternative method to treat industrial wastewater. In this study, Ipomoea aquatica and Centella asiatica were used as phytoremediation plants for removing aluminum (Al) and iron (Fe) from industrial wastewater. The results showed that the regression value (R2) for all metal concentrations (mg/L) over treatment day is positive and similar to R2 = 1. This result indicated that the metal concentration exhibits a good relationship for reflecting the decrease in the metal concentration with the proportion of treatment day. It was found that I. aquatica accumulates higher Al and Fe contents than C. asiatica. The translocation factor of both plants was found to be greater than 1, implying that both plants can accumulate and extract heavy metals from industrial wastewater.

Abstract Cengklik Reservoir is a reservoir for water from agricultural irrigation flows that use chemical fertilizers so that there is an increase in nutrients in the waters. Eutrophication is an environmental problem caused by an increase in nutrients such as nitrogen and phosphorus in aquatic ecosystems. Phytoremediation is a technique that is more efficient and economical than conventional techniques in degrading excess nutrients in polluted air. In phytoremediation, plants absorb air pollutants such as NO3-, NH4+ and PO43- directly. The purpose of this study was to examine the potential of aquatic plants in wastewater phytoremediation and provide recommendations for phytoremediation potential for the waters of the Cengklik Reservoir. The method used in this research is Systematic Literature Review (SLR). Based on the research that has been done, the Pistia stratiotes plant has been widely used as agricultural and domestic wastewater treatment. Pistia stratiotes has the potential to remove 80-95% of the phosphate content. So that the Pistia stratiotes plant is a suitable plant to be applied in the waters of the Cengklik Reservoir. The phytoremediation application was carried out in an inflow reservoir with a plant cover area of 75% of the phytoremediation area, and harvesting was carried out on the 14th day of treatment. The harvest can be utilized or managed by the community or related agencies to become a bioenergy generator.

Currently, public demand for batik continues to increase, increasing the production of the batik industry in Banten and will be the impact of increasing batik liquid waste. The results of batik production waste are usually directly disposed of through public water channels without being treated first. This condition can cause environmental pollution that will disrupt the sustainability of aquatic ecosystems. The purpose of this study was to determine the effect of phytoremediation of batik industrial wastewater on the lethality and structure of Cyprinus Carpio L. scales. This study used a completely randomized design with 5 treatments and 3 repetitions. The treatment used was the maintenance of Cyprinus Carpio L. in the wastewater from the phytoremediation batik industry with concentrations of 0%, 5%, 10%, 20%, and 40%. The results showed that phytoremediation using water hyacinth plants reduced the BOD and COD content of batik waste. Phytoremediation of batik waste affects the lethality of Cyprinus Carpio L. and the structure of the scales. At concentrations of 20% and 40%, the highest average percentage of lethality is 60% death. Fish mortality is characterized by changes in behavior such as movement activity, body balance, and color morphology. The concentration of the batik industry wastewater also affects the amount of lethality and the sublethal effect of Cyprinus Carpio L. The attachment of the waste indicates the sublethal effect to the scales, the highest concentration of which is 20% and 40%, respectively.

Full textAbstract:
In accordance with the opinion of the World Health Organization and the World Water Council the development of effective technologies for the treatment of wastewater from heavy metals for their discharge into water bodies or reuse is an urgent task nowadays. Phytoremediation biotechnologies is the most environmentally friendly and cheapest way of the treatment of wastewater, suitable for sustainable development principals. The main disadvantage of the phytoremediation is the slow speed of the process. A method for accelerating the process of phytoremediation by the combined effect of magnetic and weak electric fields is proposed. The purpose of this study is to determine the values of the parameters of the magnetic and weak electric fields that are most suitable for extracting cuprum ions from wastewater using the higher aqua plants (Lemna minor). A corresponding technological process based on the results of the study is proposed. The results have shown that the removal of copper cations from sulfate solutions effectively occurs in the initial period of time (1–5 hours) under the influence of a magnetic field with an intensity of H = 2 kA/m. Under the combined influence of an electrical current with density j = 240 μA/cm2 and a magnetic field (H = 2 kA/m) the highest rate of copper extraction by duckweed leaves is achieved. Under these conditions, the greatest growth and development of plant leaves occurs. The paper presents the results of determining of the parameters of the electrochemical release from the eluate of the spent phytomass of duckweed. It has been determined that the release of metal occurs at E = 0.32 V. An original scheme for wastewater treatment from copper with subsequent separation of copper from the spent phytomass of duckweed is proposed. In general, the presented results are a scientific justification of wastewater treatment technologies and a contribution to resolving the crisis in the field of fresh water supply. An important contribution in the circular economy is a technology recommendation proposed for recovering copper from duckweed after wastewater treatment.

Phytoremediation is a cost-effective green emerging technology with long-lasting applicability. The selection of plant species is the most significant aspect for successful phytoremediation. Aquatic plants hold steep efficiency for the removal of organic and inorganic pollutants. Water hyacinth (Eichhornia crassipes), water lettuce (Pistia stratiotes) and Duck weed (Lemna minor) along with some other aquatic plants are prominent metal accumulator plants for the remediation of heavy-metal polluted water. The phytoremediation potential of the aquatic plant can be further enhanced by the application of innovative approaches in phytoremediation. A summarizing review regarding the use of aquatic plants in phytoremediation is gathered in order to present the broad applicability of phytoremediation.

Degradation of water quality due to the presence of pollutants in water is an emerging issue in many countries, including Malaysia. Phytoremediation is one of the environmentally friendly, cost-effective conventional technologies that are still used in modern times. However, the selection of plant species is the most important aspect for the application of phytoremediation in wastewater treatment. Nevertheless, there are species of floating aquatic macrophytes that are capable of coping with various pollutants present in wastewater. Among the various floating aquatic macrophyte species, water hyacinth (WH) and water lettuce (WL) have been described as effective phytoremediators in reducing water pollution through bioaccumulation in their body tissues. Hence, WH and WL were chosen in this study as it is easily found, propagated, and cultivated. This paper aims to determine the biosorption capacity of these species in eliminating various pollutants present in wastewater as well as to define the optimum harvesting time for each species. Although these floating aquatic macrophytes are considered the most problematic plants due to their uncontrollable growth in water bodies worldwide, their ability to remove pollutants from wastewater has created a sustainable approach for their use in phytoremediation. In this sense, the use of phytoremediation by implementing the invasive floating aquatic macrophytes can certainly support the sustainable management of wastewater treatment in the future. Based on the results, it was found that WH efficiently removed higher PO43-, NO3- and NO2- concentrations compared to WL from the wastewater. Both WH and WL showed the same trend of correlation between the growth rate and sugar content, where the sugar content increased when the plants reached the highest growth rate. The maximum nutrient uptake occurred in 14-17 days, proving that nutrient availability is critical for plant growth. This study concludes that the sugar content of WH and WL are increased with the biomass growth rate, and both plants species are competent in eradicating the nutrient pollution in wastewater. On top of that, this study infers that the maximum harvesting period for WH biomass is on day 18, while WL biomass is on day 21; based on the highest sugar content and biomass weight of each species.

Full textAbstract:
The use of three macrophytes namely Azolla pinnata, Eichhornia crassipes and Lemna minor for the phytoremediation of emulsion paint wastewater was investigated. Samples of the paint wastewater and test plants were collected and analyzed for physicochemical characteristics and heavy metal concentrations before and after phytoremediation for six weeks. The TDS of the treated wastewater was reduced by over 80.0% by each of the test plants while the TSS increased as a result of debris from withered test plants. Dissolved oxygen reduction ranged from 12.5% to 50.0%, COD from 49.5% to 57.1%, BOD from 46.7% to 54.7, heavy metals from 11.0 to 92.5%. A. pinnata appears to have performed significantly better (P < 0.05) than the other plants followed by E. crassipies and L. minor. It can be concluded that the test plants (especially A. pinnata) can be effectively used for the preliminary treatment of paint wastewater.

Batik produced by craftsmen is categorized as a small and medium industry. The problem of Batik production is less attention to the environment because the craftsmen lived in the middle of a residential area that has inexperience. One of less attention to the environment is no treatment of wastewater that reaches up to 95 % (61.9 L each cloth). Thus it polluted the river. This research aimed to treat the wastewater of Batik production by using phytoremediation. In this study, phytoremediation was carried out in three tanks in series using Eichhornia crassipes and Pistia stratiotes which are abundant in Indonesia. The treated wastewater was evaluated for its ammonia and chromium (Cr). The results showed that ammonia reduced 78.36 % by E. crassipes, and 73.13 % P. stratiotes. While E. crassipes reduced Cr by 63.76 % and P. stratiotes by 83.39 %. This research concluded that E. crassipes and P. stratiotes are potential plants to reduce the pollutants in Batik wastewater.

Heavy metal pollution is a major source of pollution in the environment. Heavy metal pollution in ground and surface water threatens human health and the aquatic ecology. Traditional treatment approaches for removing pollutants from wastewater are typically expensive, time-consuming, harmful to the environment and inefficient. Phytoremediation is a low-cost, environmentally sustainable, emerging technology with a long-term application. The most important part of successful phytoremediation is plant species selection. Organic and inorganic contaminants are removed with great efficiency by aquatic macrophytes. Metal accumulator plants such as water hyacinth, water lettuce and duck weed as well as a few other aquatic plants, are commonly used to treat heavy-metal polluted water. In order to show the extensive applicability of phytoremediation, a comprehensive review about the aquatic macrophytes in phytoremediation has been compiled.

Abstract Most of Sasirangan fabric industry in South Kalimantan have not carried out an optimal wastewater treatment effort. In order to improve the quality of the waste, a combination of filtration and phytoremediation using the symbiosis of water hyacinth and Jeringau plants were applied. This study aimed to analyze the effectiveness of the filtration and phytoremediation processes using a combination of the two aquatic plants. The method used in this study was an experimental method with the treatment of a comparison of water hyacinth and Jeringau, namely 1: 3, 1: 1, and 3: 1 (w/w). The research stages are the acclimatization of the two aquatic plants for ten days, filtration with sand, gravel, and coconut fibers, and phytoremediation. The parameters tested in this study were BOD, COD, and TSS. The results showed that the combination of filtration and phytoremediation with the combination of the two water plants was able to improve the quality of sasirangan’s effluent. The best treatment for BOD and TSS was the combination of water hyacinth and Jeringau 1:1 (w/w) with the effectiveness obtained was 75.57% for BOD; and 63.93% for TSS, and the combination of water hyacinth and Jeringau at 3:1 (w/w) for COD with the effectiveness of 87.20% for COD.

Source separation of domestic wastewater into greywater (GW) and blackwater (BW) streams is important in decentralizing treatment due to its different characteristics. GW is generated from bathroom, washing machine,kitchen sink, and vehicle washing. Meanwhile, BW is produced from toilet, urinal or bidet. In developing countries, untreated wastewater is widely used in agricultural and risk to human health and living organisms. The appropriate treatment is required to prevent water degradation. Phytoremediation is a sustainable way to mitigate pollution with using plant. This study was conducted to observe the characteristics of vetiver grass as phytoremediator for GW. There are two factors of treatment. First is growth media (M), i.e. tap water (TW) as control (M0) and GW (M1). The second is vetiver (V), i.e. without (V0) as control and with planting (V1). Three glass aquariums are used for each treatment as replicates. Eight individual stem bases of vetiver were placed at aquarium and allowed hydroponically growing. At harvesting (49th day), vegetative organs were collected and observed separately, i.e. root, stem and leaf. Pollutant removal was calculated by comparing the content before and after treatment of media with vetiver. Cultivation of vetiver in GW (M1V1) could increase the root number, total root length, and total root diameter as much as 54%, 92.2%, and 51%, respectively. Individual root length was in the range of 2.3-78.5cm and root diameter was 0.35-2.10mm. Compared to the initial, stem number increased 99%, while leaf number increased 4 times. Root/Shoot (R/S) ratio was 0.80±0.14. Polutant removal of GW by vetiver achieved 72.86% BOD5; 65.51% COD; 66.55% TN; 67.67% TP; 80.77% Fe; 71.43% Zn; 60% Pb; 65.81% detergent, and 100% phenol. Vetiver could reduced TPC 29.13%, MPN coliform 78.18%, and MPN fecal coli 91.54%. After treated with vetiver, GW complied to criteria of water Class IV that can used for irrigation in agricultural.

Abstract The current study aims to improve the quality of wastewater collected from the secondary sedimentation tank of Hamdan sewage water treatment plant, Basrah, Iraq, using C. demersum L. for phytoremediation potential in the laboratory experiment. The experiments were also designed to establish some toxicological effects of wastewater on plant physiology as a response to wastewater stresses. The selected physio-chemical parameters of wastewater were conducted. Plant analyses were also measured before and after 21st day of exposure. The results showed the efficiency of the plant in improving the water quality in a different ratio. The dilution 1:3 (T3) was the most efficient with a significant difference (p<0.05) between treatment and control for most of the measured parameters. The result showed the efficiency of Ceratophyllum demersum in removing the Total hardness, Ca+2, Mg+2, BOD5, COD, NO3-2, PO4-2, Na+ and Cl- in 1:3 dilution (55.88, 13.27, 89.55, 90, 47.37, 50.65, 48.51, 16.28 and 40.24)% compared with (17.65, 5.42, 27.31, 50, 15.79, 16.30, 13.86, 6.73 and 15.77 )% in control respectively. The Ceratophyllum demersum plant has proven to be effective in improving the quality of wastewater, and therefore it can be considered an effective candidate in phytoremediation technology.
