Abstract:

The Governmental Institute for Sewage and Waste Water Treatment has studied the presence of a number of hazardous substances, selected by the EEC-Commission, in sewage and industrial waste water. The influent, effluent and sludge of six municipal waste water treatment plants and the waste water of 59 industries were sampled and analysed. Volatile chlorinated hydrocarbons in sewage originate mainly from industrial discharges. Chlorophenols, γ-hexachlorocyclohexane, polychlorinated biphenyls (PCB) and polycyclic aromatic hydrocarbons (PAH) appear to be present at a low and constant background in municipal sewage and in many industrial waste waters. The removal in the municipal treatment plants amounts to:-volatile chlorinated hydrocarbons 50–90%-hexachlorobenzene 95%-hexachlorocyclohexanes 40–65%-chlorophenols 20–40%-PCB about 90%-PAH 85–95% This study has given a survey of emissions of these hazardous substances. The total emission of the examined substances in the Netherlands has remained out of the scope of this investigation.

Abstract:

Nowadays environmental pollution is a great threat to us. Water resources are mostly polluted by industrial wastes. Among all other pollutions, water pollution is one of the most vital pollution caused by different sources like industrial, domestic, sewage, hazardous waste, municipal waste, medical waste, manufacturing waste, etc. Public concern over the impact of wastewater has increased. There are several methods for the treatment of wastewater. Among them, techniques like coagulation, adsorption, activated sludge are prominent. The use of aerobic wastewater treatment as a reductive medium is receiving attention for its low cost of operation and low cost of maintenance. The uses of low-cost adsorbents are also effective in wastewater treatment. The aerobic wastewater is effective in degrading the contaminants. There are different electrolytic techniques as well for wastewater treatment. This paper reviews the possible techniques available for the treatment of wastewater to remove contaminants such as halogenated hydrocarbon compounds, heavy metals, dyes, pigments etc. from the wastewater.

Abstract:

The biotreatment of an industrial waste oil condensate has been investigated. The waste is an oily emulsion resulting from chemical processing and condensation of grease trap wastes and industrial waste oils. The oil consists of a complex mix of hydrocarbons with significant fuel oil and lube oil fractions. Currently this waste is disposed of by incineration. The feasibility of using a biological pretreatment process to remove a significant proportion of the hydrocarbons has been investigated. Enrichment cultures produced a stable bacterial consortium. Flask cultures of this enrichment culture were capable of rapid emulsification of the oil. Within 10 days, 40–50% of the oil waste was degraded. Degradation was monitored using gas chromatographic analysis with flame ionisation detector (GC-FID) and by assessment of microbial dehydrogenase activity using triphenyl tetrazolium chloride (TTC) dye reduction. The enrichment culture consisted of 9 component organisms, 7 Gram negative and one Gram positive organisms. Their degradative abilities in monoculture have been investigated. Degradation of the waste using monocultures was monitored using GC-FID analysis of the Pristane:C17 ratio in the waste. The degradation capability of each of the component organisms in pure culture was similar to that of the consortium.

Abstract:

Basing on the theories of Environmental Kuznets Curve,this paper analyzes the relationship between industrial economic growth and waste gas,waste water and solid wastes with the economic and environmental statistics of Chongqing Municipality from 1995 to 2009. The study shows that there is a inverted N-type of environmental Kuznets curve of the industrial waste water with the rising of industrial per capita value, but it lies in the left side of the EKC. There exists a extremely notable relationship between the industrial per capita value and produced volume of industrial solid wastes,but the curve has not come up to the turning point. In order to achieve the harmonious development between industrial economic growth and environmental pollution in Chongqing,we should establish the long-effect mechanism for environmental protection.

Abstract:

With the development of metallurgy and chemical industry, with the exploitation of lean ore recourse, arsenic (As) as an associated by-product has been mined with the exploitation of the main elements. For example, we use pro-oxidation to lixiviate As-Au ore, whose particles are difficult to deal with after its exploitation, fragmentation and rubbing, floatation and nrichment; humid gas acid production is produced by As-Cu ore. These lixivium and waste liquid (industrial waste water) have certain concentration of As. According to the concentration of As, industrial waste water is classified by three kinds; Low As industrial waste water with As100mg/L; Medium As industrial waste water with As 100~300mg/L; High As industrial waste water with As300mg/L; High As can be extracted and enriched through low and Medium As industrial waste water, and then be made into single As through electrolysis sediment or hydration deoxidization. This kind of As waste water can be up to national discharge standard. This experiment is mainly about the influence of magnetic field on As industrial waste water.

Abstract:

Membranes are presently used at industrial scale for water and waste water treatment, but still for limited production. More knowledge of hydrodynamic phenomena has recently resulted in significant technical improvements (backflush, unsteady flow). However an experimental study performed at lab scale in a rotating membrane device has shown the complexity of the relationship between operating conditions, rejection and filtrate flux. The need for bettering the quality of the water (low turbidity) and waster water (disinfection) may be in favour of the development of membrane processes if efficient models allowing simultaneous optimization of quality and productivity are made available (as was done years ago for deep bed filtration).

Abstract:

Waste water from industrial sites amount to one third of total waste water discharged into Tolich river and may have serious effects on the river water quality. With the total amount of waste water of factories (Hanoi beer alcohol and beverage joint stock corporation - HABECO, Trang An JSC and Thuong Dinh industrial park) of 45000 m3/day, these factories account for more than a half of total industrial waste water released into Tolich river. The analytic results of waste water from the main factories (HABECO, Trang An JSC, Thuong Dinh industrial park, Hanoi Soap JSC, Sao Vang Rubber JSC, Tool No.1 JSC) show that the parameters of TSS, BOD5, COD, total of nitrogen, total of phosphorus are higher than the Vietnamese standards for industrial waste water QCVN 24:2009/MONRE, column B, because the factory has an effective wastewater treatment system. The heavy metals parameters of waste water from all factories without treatment: HABECO releases 1974 tons of BOD, 766 tons of TSS, 8,4 tons of phosphorus and 52,5 tons of nitrogen annually; Trang An JSC releases 64,8 tons of BOD, 48,6 tons of TSS, 0,6 tons of phosphorus, 1,6 ton of nitrogen and 25 tons of oil and grease; HASO releases 30 tons of BOD, 33 tons of TSS and 5 tons of oil and grease. Thus, if the waste water is not treated, it can lead to a very seriously pollution of Tolich river.

Abstract:

Within this research project a number of high strength organic waste waters was treated in anaerobic-aerobic working bench scale units and in small scale pilot plants. By this study problems with the anaerobic-aerobic technology should be solved, dimensioning parameters should be worked out, and the economy should be focused. For most of the sewages the anaerobic-aerobic treatment turned out to be possible although sometimes technical problems could be observed. Such problems occurred in the final aerobic stage in connection with wastes with a high content of N. They could be solved by a predenitrification stage. Fibreboard sewage was taken as an example for wastes containing persistent substances; different anaerobic processes were tested, it turned out that a twostage anaerobic treatment is necessary to stabilize the process. The economic calculations proved the anaerobic-aerobic treatment to be preferable if some conditions are considered.

Abstract:

The necessity of studying organic waste as a secondary energy resource for a waste-heat boiler with further use of the resulting ash for the adsorption of heavy metal ions is shown. The adsorptive purification of waste water from copper ions by ash of organic waste is considered. The chemical composition and technological characteristics of organic biomass, the characteristics of the boiler and the toxicity of the resulting ash have been determined. The chemical composition of the ash was obtained. The isotherm of adsorption in static conditions and the output curve of adsorption in dynamic conditions of copper cations by ash of organic waste were constructed. The process of wastewater treatment of galvanic production is presented. It is concluded that the use of the adsorption method allows for a high degree of wastewater purification and its possible reuse for the technological needs of the enterprise.

Abstract:

Application of the precipitation process using Fe and Al salts or lime, which is the main process used in Germany for phosphorus removal may lead to problems, such as an increase of the anion concentration of the water and recovering the phosphorus from the precipitation sludge. Therefore two processes for phosphorus removal from waste waters were developed which avoid these disadvantages:A process especially suitable for low phosphorus concentrations (≤1 mg/L P) employing Activated Alumina for the removal of the phosphate by adsorption.Phosphorus removal by means of direct precipitation of calcium phosphate induced by calcite as seeding material for the treatment of higher concentrated waters (≥20 mg/L P).

Abstract:

Industrial water usage results in large volumes of liquid wastes rich in organic pollutants. Waste waters from certain industrial chemical operations (e.g. organic synthesis, perfume industry) will sometimes contain organic solvents at relatively high concentrations. The presence of organic solvents is undesirable in the sewerage system and so must be removed from the industrial effluent. Anaerobic treatment of many of these organic solvents is possible, in which the organic material is converted ~90% to volatile substances -carbon dioxide and methane gas- and ~10% to new bacterial cells (solids). Industry will be using less water in the future. Increased water charges will lead to more precise control and integrated processes will reduce wastage. The smaller volumes of more concentrated waste will be ideal for anaerobic digestion. In order to evaluate the optimum conditions for the anaerobic digestion of propan-2-ol (iso-propanol) the kinetic parameters of the Monod rate model, namely, maximum growth rate (µm), yield (Y), half velocity constant (Ks) and endogenous decay coefficient (Kd), were determined at the temperature range 25°-40°C, inclusively. The regulatory role of molecular hydrogen was investigated and discussed, and also its possible use as a monitor feature in the anaerobic digestion.

Abstract:

This paper compares and discusses the results of two solid waste surveys done by CETESB, the State of Sao Paulo environmental control agency, in the São Paulo Metropolitan Region. The objective is to get an idea of the accuracy of the results, as well as to establish points that can be considered in an industrial solid waste control policy for the region. The results of the two surveys were consistent with each other. The results were also checked against the amount of non-domestic waste that is disposed of in the sanitary landfills operated by the city of São Paulo, to verify the accuracy of the estimates. It was estimated that in the Region 3,250,000 t/year of industrial solid waste were generated in 1988, 376,000 t/year being hazardous. The recycling ratio is high, 27% for the hazardous waste, but the recycling industry is formed by small companies which are causing a lot of environmental problems. The municipal landfills receive relatively small amounts of hazardous wastes. There are large amounts of these wastes being disposed of in particularly dangerous forms: soil infiltration, impoundments and open dumps. Storage in drums is the second method used to dispose of hazardous wastes. Finally it is recommended that the State authorities take into account the above points in formulating the industrial waste control policy for the Region.

Abstract:

Nanomaterials play a vital role in healthcare, electronics, manufacturing industries, biotechnology, and security systems. One such material is graphene and its oxides are specifically used for recycling industrial waste water. Graphene, a single layer in honeycomb cross section, provides excellent attention because of its significant optical, mechanical, and physical properties. GO was utilized to decrease the acidic or essential centralization of the mechanical wastewater into reusable water for the modern reason utilizing graphene channels. In this paper, sample solution (waste water) is taken from paper industry. Graphene channels can be created from the pencil graphite. Graphene has the high goals of separating capacity, and graphene is considered as “a definitive RO film” in light of its stronger, thinner, and more chemically safe nature than the polymer layers. Graphene oxide layers are likewise to be used in the desalination plant in place of the RO membrane.

Abstract:

In an underground R.C. Tunnel constructed as conduit for SS Pipes carrying industrial waste liquid, heavy ingress of ground water was witnessed and had to be overcome. Industrial wastes are to be carried through pipes in pipe system with an outer casing of a 200 mm dia SS pipe. Continuous contact of ground water with the casing SS pipe will deteriorate the pipe with the consequence of mixing of waste with the ground water. To avoid this, tunnel was sealed by enclosing the casing pipe with self-compacting concrete (SCC) for preventing ingress of ground water into the tunnel. As sustainability comprise Economy, Environment and social impact, the use of SCC take care the above factors by utilizing fly ash which replaces cement ,thereby, protecting the environment from industrial waste to produce socially accepted concrete and ensuring sustainable construction.

Abstract:

At Vinh Loc industrial zone, people exploit well-water for domestic purpose. Pleistocene and upper Pliocene aquifers have been exploited primarily because of their qualities. The authors carried out a survey of surface water and ground water quality at the industrial zone to clarify the effect of waste- water to running water. Well-water samples were collected at both two aquifers and arranged toward underground flow. In addition, some of waste-water samples were also collected. The results showed that well-water quality is good, however, ammonia, iron, coliform, suspended solid were found in waste- water and exceeded the standard. The authors accessed influenced ability of waste-water to ground water by studying hydrological geology features of this area. Some of well-water samples had iron, ammonia content that exceeded the standard. It may be due to waste-water from the industrial zone. The surface water received the waste-water and geological features were the favorable conditions for polluted substances that can be flow to aquifers for time.

Abstract:

A study on the adsorption of copper (II) ions from the aqueous solution on waste wool had been carried out to analyze the adsorption capacity of waste wool, thereby aiming towards mitigation of metal ion pollution in industrial waste water. The effect of varying concentration of copper ions and varying time period, was studied on fixed weight of waste wool. The initial and final concentration of copper ions was measured by conductometric and spectrophotometric methods. Adsorption data were modeled with the langmuir and freundlich adsorption isotherms. The isotherm and first order equation were found to be applicable. Removal of metal ions using industrial waste wool is found to be favourable. Thus the work can be extended to study various physico-chemical parameters for removal of copper (II) ions from industrial effluents using waste wool. A later work can be involved where the waste wool adsorption parameter can be further utilized for composite ceramic products.

Abstract:

Industrial wastes generally pumped into water bodies and soil that would pollute the atmosphere. As a control measure, industrial wastes products utilized as waste building materials. In the present research, waste products from various industries like illuminate sludge and glass bottle powder used in different dosages as a replacement for fine aggregate and metakaolin used as a cement replacement. Split tensile strength and compressive strength of the concrete samples examined for M30 grade. Fine aggregate is substituted by glass bottle powder (i.e. 10 to 40%) and illuminate sludge (i.e. 10 to 30%). Metakaolin substituted for cement replacement (i.e. 4 to 12%). Glass bottle does not pollute the atmosphere, but the disposal of waste glass results wastage of land. Thereby glass bottle powder can be utilized as a cement replacement in the construction industry. Then the metakaolin and illuminate sludge are the waste products from the titanium product. The experiment performed to assess the strength properties by incorporating various industrial wastes in different dosages. Physical tests of all three products have carried out according to the code requirements. Three specimens have been tested for each industrial waste products ratio to examine the tensile and compressive strength of concrete at 7th day, 14th day and 28th day and eventually to cure to achieve the optimum strength of concrete. Addition of these industrial wastes into the concrete showed an outstanding improvement in modulus of rupture, split tensile strength and compressive strength at an early and later ages.

Abstract:

It is, clearly, a Government responsibility to enact laws and promulgate regulations for control of industrial pollution. The main techniques for soil industrial wastes disposal, namely, landfarming and landfilling, profit from the extensive knowledge acquired, in past decades, in the field of water and air pollution control and must be analysed within a comprehensive system for hazardous waste management, with its legal and administrative aspects. This paper presents some general principles of a Hazardous Waste Management System, which are broadly applicable, regardless differences between States or Countries. Finally, it discusses the specific case of Hazardous Wastes Management in the State of Bahia, Brazil and makes some suggestions for its improvement.

Abstract:

The clean river is very important for human life and river’s biota. However, many rivers are polluted from both domestic and industrial waste today. Domestic waste comes from households and industrial wastes from nearby industrial activities. One of the biotas of the river is the fish. The objective of the research was to evaluate pollutant and pollutant index in the watershed and the present of Pb in fish in the watershed. The location of this research was a long Garang watershed Semarang, namely from upstream to downstream of the river. The sampling area was divided into 7 segments based on Central Java Governor Regulation No. 156/2010 based on water designation. The studied parameters in this research were heavy metal in fish and water quality. The studied fish was Nila fish (Oreochromis sp.). Results show that Cu was the main pollutant in water river class 1, 2, 3 and 4. DO exceed the limit parameter in water river class 3 and 4. Finally, the highest heavy metals found in fish were found in Pb, while the water pollution index was due to exceeding Cu, all of which came from industrial waste.

Abstract:

AbstractThe adsorption by different silicate minerals of some heavy metals, present in industrial waste water, has been studied. These adsorbents (mainly clay minerals) are readily available, inexpensive materials and offer a cost-effective alternative to conventional treatment of wastes from the metal finishing industry. The results show that some mineral species are suitable for the purification of such residual waters down to the limits prescribed by current legislation concerning industrial wastes. The Langmuir model was found to describe such adsorption processes best. Sepiolite (Orera, Spain) has an adsorption capacity of 8.26 mg g-1 for Cd2+, the capacities depending on the metal adsorbed in the order: Cd2+ > Cu2+ > Zn2+ > Ni2+. This mineral shows the highest sorption capacity relative to the other minerals studied. Factors in the reaction medium such as pH and ionic strength influenced the adsorption process.

Abstract:

Abstract Nitrogen and phosphorus belong to most important biogenic macro elements and both are required for the growth of microorganisms. Sewage waste waters and industrial waste waters from nitrogen production are important sources of organic and inorganic nitrogen compounds in water. Surface water predominantly contains nitrogen in a form of ammonium cations (NH4 +). This knowledge could be used in waste water treatment. The paper deals with a potential application of ozonation in waste water treatment to treat waste water polluted with excessive amounts of organic compounds, primarily containing nitrogen and its subsequent co-application with advanced oxidation processes (AOPs).

Abstract:

The object of the study is the water supply and sanitation system of an industrial enterprise. Currently, many enterprises do not use the treated industrial waste water in the water supply cycle. Therefore, the use of treated wastewater is of practical importance. The scheme of thermal treatment of waste water for obtaining pure condensate by evaporation is proposed. The main results of the study are the technical solution for the development of the enterprise's wastewater treatment complex. Pure condensate is obtained in an instant boiling evaporator. The research method is based on the calculation of energy costs in wastewater treatment for different types of waste water. The results of the study allow us to determine the optimal set of energy equipment for obtaining pure condensate and its further use. The specific practical significance lies in the development of a technical solution that helps the treatment of wastewater and the reduction of emissions into the water basin.

Abstract:

Abstract The reuse of pollutant solid wastes produced in distinct industrial activities (avian eggshell waste and welding flux slag waste) as a source of alternative raw material for producing soil-cement bricks for civil construction was investigated. Soil-cement bricks containing up to 30 wt% of industrial solid waste were uniaxially pressed and cured for 28 days. Special emphasis is given on the influence of solid waste addition on the technical properties (as such volumetric shrinkage, water absorption, bulk density, durability, and compressive strength), microstructure and mineral phases of soil-cement bricks. Microstructural evolution was evaluated via confocal microscopy. The experimental results showed that the solid wastes behave as charge material and influenced both technical properties and microstructure of the soil-cement bricks. It was found that up to 15 wt% of welding flux slag waste and up to 30 wt% of avian eggshell waste could be added into the soil-cement bricks for use as building material.

Abstract:

This paper was aimed to examine the removal of oil from water by photocatalytic advance oxidation under solar light. A pH of 11 has shown a higher oil removal efficiency. Oil remove efficiency levels at pH 11 have been found 75% within 230 minutes’ oily water effluent, studies have shown that Langmuir isotherm has been the best-fit one of the isotherms for the removal of oil. Data have shown a higher adsorptive capacity. Also we have studied another parameter like (catalyst concentration, initial oil concentration and pH). While the treatment of waste-water is dependent upon a great level of quality for the processed industrial water, the nature of wastes that are added throughout the utilization, and the treatment degree that has been received by the waste-water. Then, the data of the waste-water quality that has been measured rou-tinely and it was reported at the plants of the waste-water treatments are mainly for disposal of the treated effluent or the necessities of the discharge in terms of the gross pollution parameters.

Abstract:

A microbial fuel cell (MFC) is a device that converts bio-chemical energy into electrical energy during substrate oxidation with the aid of microorganisms (bacteria). The energy contained in waste water is converted to the electrical power by the action of bacteria. The principle of MFC is to transfer electrons from the microorganisms to electron acceptor at a higher electrochemical potential. An experimental study was performed to find the most efficient industrial waste water that can produce highest and stable electrical power by the MFC and to determine the removal rate of pollutant from the waste water by the MFC. Two MFC, namely one PEM MFC and two PEM FMC, has been fabricated for this study. The three different waste water samples used were Dyeing Waste Water-1 (DWW-1), Dairy Industry Waste Water (DIWW) and Dyeing Waste Water-2 (DWW-2). The highest rate of voltage generation is achieved when the MFC was operated with DWW-1 (1.06 V), DIWW (0.95 V) and DWW-2(0.644 V), respectively. Based on the graph pattern the DWW-1 provided the best record in terms of electrical energy generation.

Abstract:

The pharmaceutical industry produces a various toxic wastes. Generated waste increases the risk of environmental and ecosystem pollution. It is necessary to have proper waste management to prevent waste pollution to the environment. In 1999, WHO published “Guidelines for the Safe Disposal of Unwanted Pharmaceuticals in and after Emergencies”, that contain treatments and safe disposal method, which is appropriate for any country. Many countries had developed and published regulations and guidelines on waste management. This article aimed to review the handling of pharmaceutical industrial waste in five countries in Asia. This review included studies from ProQuest, Crossref, and Google Scholar. The pharmaceutical industries in Indonesia, India, Japan, Thailand, and China has their own state regulations in order to protect the environment. They also had implemented pharmaceutical industrial waste management following their regulation and guidelines. The method used to treat the waste is similar with WHO guideline. Some factors affecting the country regulations are the insufficient of land and waste management facilities, lack of awareness, low penalties, limited infrastructures, lack of waste testing facilities. The challenge in the future to handle pharmaceutical waste are increasing waste volume, decreasing land for waste management, sewer methods may contaminate water, possible air pollution due to incineration, so it is necessary to have more advanced methods in waste management that are safe for the environment and humans.Keywordz: Industry, Pharmaceutical, Waste Regulation, Asia

Abstract:

Abstract Biodegradability of pollution contained in examined industrial wastewater was assessed according to methodology based on Zahn-Wellens (OECD 302B) test. The following kinds of wastewater were examined: - metal industry wastewater from aluminium pressure foundry; - wastewater from industrial waste treatment processes, such as: filtration waste, chemical reagents, coolants, water emulsions, oil wastes and other industrial wastes, galvanising waste treatment processes sludge. Samples COD value decrease in the subsequent days of the experiment proves that organic substances contained in the examined wastewater undergo gradual biodegradability in aerobic conditions. The highest biodegradability degree of aluminium pressure foundry wastewater equal 65.7% was noted during 28 day of the experiment. However, the minimum biodegradability degree equal 80% after 13 aeration days, which in Zahn-Wellens test allows to determine the examined substance to be biodegradable, has not been achieved. Meanwhile, Zahn-Wellens test conducted for wastewater from industrial waste treatment processes showed that in the day 14 of the process, high (87.1%) organic substance degradation degree, measured with COD value decrease, was achieved. Further aeration of the samples did not increase biodegradability, which equalled 87.9% after 28 days.
