The main objective of this study was to evaluate the efficiency of a granular filtration system (GFS) in greywater treatment under arid and semi-arid conditions. Six GFSs were designed, constructed, and monitored for approximately 13 months. Each GFS served a single rural Jordanian home by treating their greywater. Volcanic tuff media were used as the filtration media in three of the GFSs while the remaining three GFSs used gravel media. Results show that the biological oxygen demand, chemical…

Horizontal Flow Constructed Wetland for Greywater Treatment and Reuse: An Experimental Case

A comparison with international recommendations by World Health Organization and European Union is discussed and very high removal yields on turbidity, total suspended solids, and five-day biological oxygen demand are discussed.

Impact of a Sand Filtration Pre-Treatment Step on High Loaded Grey Water Treatment by an Electrocoagulation Technique

Greywater (GW) treatment by the electrocoagulation (EC) technique alone might not meet the required standards in terms of pollutant removal, specifically when GW contains high loads of pollutants. In

Household greywater treatment using phytoremediation technology and CapsNet model

In recent decades, recycling of wastewater has received increasing attention among researchers, because it can satisfy the proliferating demand for groundwater and reduce water shortages in developed

Graywater treatment technologies and reuse of reclaimed water for toilet flushing

It is viable to use graywater purified by MBR for toilet flushing and the water quality of the effluent of MBR-treated GW was better than that of the mixed wastewater, providing a scientific basis for the popularization and application of reclaimed water for toilets flushing.
