Environmental impact of irrigation with greywater treated by recirculating vertical flow constructed wetlands in two climatic regions

by IWA Publishing  (Jun. 25, 2014)

Reuse of greywater (GW) has raised environmental and public health concerns. Specifically, these concerns relate to onsite treatment operated by non-professionals; systems must therefore be reliable, simple to use and also economically feasible if they are to be widely used. The aims of this study were to: (a) investigate GW treatment efficiency ...
