Entry Knowledge

Student gets the aim of subject under control, i. e. basic processes of wastewater treatment: ion exchange, extraction, stripping, clarification, adsorption, coagulation, neutralization, separation of light particles, separation methods on principle of semi-permeable membranes, filtration, aerobic reactors, elimination of nitrogen and phosphorus.

Aims

Subject is focused on acquiring knowledge of basic chemical and physico-chemical processes of wastewater treatment.
