AbstractGreywater (GW) has attracted global attention as an alternative water source over the last few decades. GW treatment andreliable reuse require the overall qualitative characterization of samples from different sources. This paper represents aninvestigation of household-generated GW in the Northern Great Plain Region of Hungary. Modern and reliable analyticaltechniques and instruments (ion chromatography, microwave plasma atomic emission spectrometry, Zetasizer Nano Z analysis,etc.) were ...

The objective of the present study was to (i) compare different treatment options for greywater (GW) reuse, (ii) assess the potential of treated GW for reuse, and (iii) select the optimal treatment option by using Analytic Hierarchy Process (AHP). Raw GW was settled for 2 h. Five different treatment options were investigated simultaneously in parallel using the same influent (settled GW). The treatment options were (1) sand filtration, (2) sand/brick bat filtration, (3) alum coagulation/floc...

In the light of water shortages, frequently affecting many regions worldwide, domestic rainwater harvesting, and greywater reuse systems represent an alternative source of water. This study fits this framework providing a hydraulic/hydrological model developed by means of the EPA’s Storm Water Management Model. The model has been applied to a case study, which consists of an apartment building located in the city of Bologna and equipped with a hybrid rainwater-greywater recycling system. C...

Greywater reuse is widely accepted as a suitable response to the increasing demand of fresh water in urban areas. On the other hand, strict environmental regulations have obligated the development and implementation of membrane separation technologies for production of municipal potable water, in industrial water supply and in wastewater treatment. Potential energy crisis in the future has highlighted the importance of using renewable source of energy for membrane separation processes. This r...

Water shortage is one of the most worrisome issues around the globe, especially with the increase in the human population. Nowadays, attention has been drawn towards the reuse of greywater because of its large volume and low contaminants. In the present research, greywater samples were collected from different sources including; households, restaurants, mosques, laundries, guest houses and sport clubs in Mansoura city, Egypt. The counts of total coliforms, Escherichia coli, Enterococcus sp., Ps...
