Several on-site greywater treatment systems are under development including biofiltration, whose efficiency is influenced by the filter media. Therefore, main objective of this study was to evaluate influence type media and their grain size in removal organic microbial pollutants from greywater. Hence, three types local different were used for pre-treatment Their potential clogging time evaluat...

These days, many countries have a water shortage and limited access to clean water. To overcome this, new treatment is emerging, namely, the photocatalytic processing of greywater. Photocatalytic processes remove organic matter from different greywater sources are critically reviewed. Their efficiency in degrading scrutinized along with factors that can affect activity photocatalysts. Modified ...

The current study analyses the performance of deep sand filtration of greywater from an office building and the performance of a combined physicochemical process comprising of coagulation, sedimentation and filtration. Raw greywater quality exhibited very high variability with average turbidity of 35 NTU, and TSS, COD(t), and BOD of 45, 240, 75 mg/l respectively. The stand-alone filter removed ...

Abstract The goal of our research is to study the treatment possibilities laundry water fraction domestic greywater as an alternative source, well apply a complex method with which we obtain purified greywater. This treated can be used during household tasks that do not require drinking water. By optimizing each step, determined process following steps: coagulation- quartz sand filtration-oxida...

To meet the increasing global water demand, local solutions, such as reuse of greywater, are becoming greater importance. While greywater reclamation has been implemented, full-scale adaptation limited by occurrence micropollutants in treated effluent. reduce risks posed micropollutants, advanced post-treatment is required. One promising technology implementation hollow fiber nanofiltration, wh...

Household wastewater, especially from conventional septic systems, is a major contributor to nitrogen pollution. Alternative household wastewater management technologies provide similar sewerage management services but their life cycle costs and nitrogen flow implications remain uncertain. This paper addresses two key questions: (1) what are the total costs, nitrogen mitigation potential, and c...
