WASS

WASS is a decision guidance system that can help in the initial screening of possible techniques for the treatment of industrial waste water. The objective of WASS is not to automatically propose the Best Available waste water treatment technique based on the input data, but rather to select a number of possible techniques from which the expert can select the Best Available Technique. The decision guidance system itself can only be consulted in Dutch. The technical descriptions of the techniques are available in English as well.
