Learning outcomes of the course unit

Student will gain knowledge about basic wastewater treatment after graduation this subject. They will obtain theoratical and also practical skills, which this subject contains, for example ion exchange, extraction, stripping, clarification, adsorption, precipitation processes, neutralization, light particles separation, semipermeable membranes, filtration, anaerobic reactors, nitogen and phosphorus removal.

Prerequisites

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

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Education activities in this subject are determined by classical scheme. They are divided into theoretical part, which is presented by lectures and practical part, which is presneted by laboratory sessions. The practice contains calculation of examples which are related to the experiments.

Assesment methods and criteria linked to learning outcomes

A student must complete laboratory sessions, which is confirmed by attendance and consign procotols from particular laboratory excercises. In the end of the term student must complete written midterm test which contains knowledge aquired in laboratory sessions and then they take an examination in the range of knowledge from the lectures.
