Entry Knowledge

Physical properties of water, chemical balance in the water, characteristic composition of water, gases in water, pH, neutralisation capacity, calcium-carbonate equilibrium, water hardness, the living conditions of microorganisms in water, biochemical processes in the waters, natural ways of wastewater treatment, inorganic nomenclature, basic organic nomenclature, compiling chemical equations, stoichiometric calculations, concentration and its expression.

Aims

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

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.
