Abstract:
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.

Abstract:
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

Abstract:
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

In this study, we reviewed greywater characteristics and various treatment technologies with the aim of coming up with the schematic of greywater recycling system designed specifically for restricted agricultural irrigation reuse. Characteristics of greywater are highly variable; greywater amount varies from 50% to 80% of the wastewater volume produced by households. All types of greywater show good biodegradability in terms of COD: BOD5 ratios. The ratio of BOD5/COD in greywater ranged from 0.31 to 0.71.

Abstract The recycling of greywater for non-potable water applications, such as toilet flushing or irrigation, is a potential solution to reduce potable water consumption. To estimate the quality of raw greywater samples, we measured several physical, chemical and biological parameters. We used Hygiene Monitor test kits to determine microbiological presence in the samples. The greywater samples showed a high variability for all the measured parameters. In general, we found that greywater sources had lightly alkaline character with a considerable inorganic and organic content. About half of the

Abstract:
There is an increasing trend to use greywater for irrigation in households. This is partly due to the notion that greywater is of better quality than wastewater and therefore does not need extensive treatment beyond addressing public health issues. The aim of the study was to evaluate the environmental impact and health risks associated with the use of greywater for irrigation on a small private farm. Over a three-year period, each of three plots on a farm was irrigated with either freshwater, fertilized water, or greywater. Irrigation water and soil from the plots were analyzed for a wide ran

Abstract Greywater, comprising household wastewater excluding toilet waste, represents a significant portion of daily wastewater. Effective greywater treatment is crucial to mitigate environmental pollution, especially when greywater flows directly into water bodies without clear controls, discharge limits, and treatment requirements. Nature-based solution (NBS) approaches, such as green roofs, are gaining popularity for their urban benefits and potential for greywater treatment. However, in Malaysia, the application and literature on green roofs are limited, primarily focusing on stormwater m

Second, to determine whether irrigation water that has percolated through a green walls soil matrix can be further recycled and reused.

The imported water has a large carbon footprint due to using grid power for water transport.
