Resumen

Abstract In our research we pre-treated synthetically produced greywaters with filtration on various filters. We characterised the quality of greywater samples using several parameters. We investigated these parameters on the untreated and pre-treated samples as well. We evaluated the efficiency of the treatments by measuring the characteristic parameters. It was shown that the most effective pre-treatment for the greywater’s preparation for reuse is filtration on silica sand or activated charcoal and silica sand combined filter media.

Resumen

Greywater, a type of domestic wastewater, is a potential solution to global water shortages, which are expected to affect 2.7 billion people by 2025. Greywater is safer to handle and treat than black water, making it suitable for non-potable uses like toilet flushing and landscaping. It also promotes ecologically sustainable development by reducing freshwater extraction, energy use, and chemical pollution. The process of processing greywater involves considering factors like biological oxygen demand, surfactants, oil and grease, and detergent residues. This study was evaluated greywater’s phys

Resumen

Greywater refers to wastewater generated from domestic activities, which do not contain fecal contamination. Therefore, this study aims to treat greywater in Makassar city to speed up the water cycle and enable reuse, as an environmental conservation strategy. The water parameters measured were pH, Turbidity, Total Suspended Solid (TSS), Biological Oxygen Demand (BOD), and Chemical Oxygen Demand (COD). According to the results, the greywater’s BOD, COD, and TTS contents were 49.98 to 54.88 mg/L, 509 to 655 mg/L, and 404.40 to 464.65 mg/L, respectively, all of which exceed WHO wastewater qualit

Resumen

Greywater normally represents the largest fraction of wastewater generated in buildings and may be suitable for non-potable reuse after on-site treatment. Conventional technologies for greywater treatment include sequencing batch reactors, membrane filtration, and membrane biological reactors. Even though these can be very effective, they are highly energy consuming and may negatively impact the energy balance of the building where they are installed. Microbial fuel cells (MFCs) have emerged as a sustainable technology for contaminant removal and energy production from a variety of substrates.

Since Tacna is a hyper-arid region, greywater is a potential alternative water source. This study aimed to quantify and characterize greywater in a university building with 732 students, as well as assess their perception of greywater reuse. Water meters were used to calculate greywater quantity. To assess untreated greywater quality, physical–chemical and microbiological parameters were analyzed. Questionnaires were used to measure students’ acceptance regarding greywater reuse using a Likert scale. The greywater quantity recorded in this study was 426.85 L/d, which is less than reported in p

Resumen

The reuse of greywater is steadily gaining importance in South Africa. Greywater contains pollutants that could have adverse effects on the environment and public health if the water is not treated before reuse. Successful implementation of any greywater treatment process depends largely on its characteristics in terms of the pollutant strength. This study investigated the physico-chemical characteristics of greywater from different sources within 75 households in a community in Durban, South Africa.

The benefits of greywater reuse have been identified to include the protection of water resources, recovery of nutrients for agriculture, savings in fresh water usage, reduction in volumes of wastewater discharged into wastewater treatment works, groundwater recharge and sustainable water resource management. An understanding of public attitude and perceptions towards the reuse of greywater will help to facilitate a positive reaction to the promotion of such concepts.

Resumen

Water scarcity is a growing concern in many metropolitan area, especially in Nigeria. As a result, non-potable uses like irrigation are increasingly depending on alternative water sources. A potential resource for urban gardening is greywater, which is wastewater from domestic tasks like laundry, bathing, and dishwashing. This is especially true when it comes to growing indigenous herbs that have nutritional, therapeutic, and cultural significance. Despite its potential, the acceptance and awareness of greywater reuse for irrigation remains limited. Therefore, this study documents knowledge an

Abstract The characteristics of greywater generated in two rural areas (“Barkoundba” and “Kologoudiessé”) located in the Sahelian region in Burkina Faso were assessed through observations in selected concessions, sample collection and laboratory analyses. The study aimed at characterizing the qualitative and quantitative characteristics of greywater in order to evaluate its reuse potential for gardening in rural areas. The results showed that greywater is generated from 3 to 4 main sources with average daily productions of 8 ± 1 L•capita‑1•d‑1 in “Barkoundba” and 13 ± 3 L•capita‑1•d‑1 in Kolog

Resumen

Increased production of greywater prompted by the rise of urbanization and increased population in the industrial era is a growing environmental concern exacerbating the apparent water insecurity. Treatment and reuse of greywater is a promising solution to this problem since it will divert the use of limited freshwater resources to unavoidable consumptive uses. This study reviewed the various methods used to treat greywater and the progress made in taking up the practice in Kenya.

The world population has topped 8 billion and water scarcity is rising because of the effects of climate change. The addition of plants to interior and exterior spaces has positive emotional, but questionable environmental, benefit when potable water sources are used for maintenance. To preserve potable water for human use, nonpotable resources, such as greywater, may be used as an alternative for the growth of ornamental plants.

Abstract The aim of our research was to investigate the detergent content and several micro and macro elements in greywater samples, a necessary step in determining the water quality for the further reuse of the greywater. We determined the anionic detergent content of synthetic greywater with a two-phased titration method prepared in laboratory conditions. The current study leads to a new suggestion for a more accurate and reliable titrimetric method for determination of anionic detergent content of synthetic greywater samples. Following these investigations, we also examined the metal conten

Global water scarcity is becoming an increasingly critical issue; greywater reuse presents a promising solution to alleviate pressure on freshwater resources, particularly in arid and water-scarce regions. Greywater typically sourced from household activities such as laundry, bathing, and dishwashing, constitutes a significant portion of domestic wastewater. However, the reuse of greywater raises concerns about the potential risks posed by its complex composition. Despite the growing body of literature on greywater reuse, most studies only focus on specific contaminants, thus there is a limite

However, the health risk associated with the microbial contents of these waters limits their utilization. Many techniques have been developed and used to generate a high microbiological quality of greywater. The main problem in the treatment of greywater lies in the nature of pathogenic bacteria in terms of their ability to survive during/after the treatment process.

On-site greywater recycling and reuse is one of the main ways to reduce potable water requirement in urban areas. Direct membrane filtration is a promising technology to recycle greywater on-site. This study aimed at selecting a tubular nanofiltration (NF) membrane and its operating conditions in order to treat and reuse greywater in buildings. To do so, a synthetic greywater (SGW) was reconstituted in order to conduct experiments on a reproducible effluent. Then, three PCI NF membranes (AFC30, AFC40 and AFC80) having distinct molecular weight cut-offs were tested to recycle this SGW with a co
