On-site greywater treatment and reuse in multi-storey buildings.

The paper presents a study of a pilot plant treating light greywater for seven flats. The pilot plant combines biological treatment (RBC) with physicochemical treatment (sand filtration and disinfection). The pilot plant produced effluent of excellent quality, meeting the urban reuse quality regulations, and was very efficient in TSS turbidity and BOD removal: 82%, 98% and 96%, respectively. CO...

Greywater Treatment and Reuse Using a Baffled Constructed Wetland

Water is one of the world’s most valuable resources. However it is under constant threat due to urbanization, explosive population growth and pollution. The most promising efforts to stem water crisis are to treat the wastewater in a sustainable way and reuse for non-potable applications. Grey water (GW) being highly voluminous and relatively less polluted, recycling for non-potable uses like u...

Presence and fate of priority substances in domestic greywater treatment and reuse systems.

A wide range of household sources may potentially contribute to contaminant loads in domestic greywater. The ability of greywater treatment systems to act as emission control barriers for household micropollutants, thereby providing environmental benefits in addition to potable water savings, have not been fully explored. This paper investigates the sources, presence and potential fate of a sel...
