WASS (water treatment selection system)


WASS is a decision-support tool that helps the government, companies and environmental consulting firms in their search for possible combinations of treatment techniques to solve a particular wastewater problem. WASS was developed by the BAT knowledge centre. However, the outcome is not automatically a Best Available Technique (BAT). For this purpose, a global environmental and economic assessment, and a more specific analysis of techniques needs to be made. The technique sheets of WASS can also be consulted in book form. The ‘Guide Waste water treatment techniques - Second version’ can be ordered at Academia Press (orders@academia-press.com).

Click Techniques in the left menu to consult the electronic version of the technique sheets.
