Learning outcomes of the course unit

Acquisition of comprehensive knowledge on technological processes of drinking water treatment of surface and ground water sources. Students will gain insight into the water treatment technology, which will enable them to take positions of either technologists in water treatment plants or junior scientists in water research field. Enough effort is devoted to presentation of emerging technologies and trends in water treatment. This is based on both, foreign literture and personal experience of the teacher. Examples of practical solutions of some real problems of water treatment plants in Czech Republic and Slovakia will enhance the scope of the presentations.

Prerequisites

Knowledge from courses Hydrochemistry, Analytical chemistry, Chemical engineering, physical chemistry
