Review of the technological approaches for grey water

Friedler et al. (2005) studied a low strength grey water treatment system, which combined RBC, sand filtration and chlorination. The RBC step was preceded by a fine screen for the removal of gross solids and hairs larger than 1 mm and followed by a sedimentation step in a sedimentation basin to separate sludge from the effluent.
