Cleaning and reuse of the sewer-drainage waters

The article gives qualitative and quantitative characteristics of river and sewer-drainage waters of the Aral Sea basin. We investigated their chemical composition in terms of macro- and microcomponents. It was established that due to the discharge of drainage waters the contents of salts and pollutants in river waters increases. We substantiated the expediency of cleaning and reuse of drainage waters for different purposes. The paper showed the possibility of their demineralization by membrane methods.
