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

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...

Performance of UV disinfection and the microbial quality of greywater effluent along a reuse system for toilet flushing.

This paper examines the microbial quality of treated RBC (Rotating Biological Contactor) and MBR (Membrane Bioreactor) light greywater along a continuous pilot-scale reuse system for toilet flushing, quantifies the efficiency of UV disinfection unit, and evaluates the regrowth potential of selected microorganisms along the system. The UV disinfection unit was found to be very efficient in reduc...

Greywater, a New Alternative Approach for Domestic Wastewater Separation and Reuse in Iran

Assessment of the reliability of an on-site MBR system for greywater treatment and the associated aesthetic and health risks.

This study analyses the reliability of an on-site MBR system for greywater treatment and reuse. To achieve this goal simulation was performed based on the IWA ASM1 model which was adapted to describe biological and physical mechanisms for MBR greywater treatment based systems. Model results were found to agree well with experimental data from an on site pilot greywater treatment plant, after wh...

Greywater Characteristics and Reuse in Tower Gardens in Peri-Urban Areas – Experiences of Kawaala, Kampala, Uganda

This study was undertaken to create an understanding of greywater characteristics and to demonstrate a low cost reuse option involving application of small tower gardens for Greywater treatment and reuse in a peri-urban settlement, Kawaala in Kampala city, Uganda. To realise this, field surveys, greywater and soil sampling and analysis and, tower garden installation at selected households were ...
