The importance of sullage (grey-water) treatment for the restoration and conservation of urban streams

Sullage (grey-water) is one of the major point pollution sources, which is discharged from residential and commercial areas into the rivers without any treatment. This study was conducted to determine the pollution characteristics of sullage from a 6.14-hectare residential area where it is discharg...
