Removal of detergents in car wash wastewater by sub-surface flow constructed wetland

Suspended substances in car washes can often be easily removed by physicochemical processes. The main problem is to remove dissolved such as detergents from the water. In this study, a biodegradable substance Sodium Lauryl Sulfate (SLS) was wash wastewater use of Phragmites australis subsurface constructed wetland. For 4 plexiglass reactors having an effective volume 10.8 L with dimensions 15cm×45cm×20 cm were used. experiments conducted vegetation which called SCW and without named control group (CG), two groups. A serial connection performed for each group. Up 90% detergent removal observed loading rate 75 L/(m2.d) effluents quality showed that treated water reused carwash or irrigation landscaping.
