Water Treatment Technologies

FCH-MCO_TUVAcad. year: 2012/2013

The properties of natural waters related to drinking water treatment, standards of drinking water quality, classification of water treatment processes, disperse systems and their stability, coagulation and aggregation in water treatment, determination of optimal coagulant dose, coagulation kinetics, separation of suspensions, influence of mixing. Separation processes: sedimentation, flotation, filration, sorption, membrane processes. Removal of iron and manganese. Sludge handling and disposal. Oxidation of organic and inorganic substances in water. Disinfection of drinking water: chlorination, dechlorination, ozonization, chlorine dioxide, UV radiation. Biological methods of water treatment, biological stability of water. Corrosion and corrosion control of water distribution systems, water softening and hardening, removal of carbon dioxide, supervision of technological processes of water treatment.

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

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Lectures are based on extensive use of well documented presentations, which support the theory with additional research and practical information. Because of technological nature of this subject, all themes recall the previously gained theoretical knowledge, especially in aquatic chemistry, hydrobiology and limnology, physical chemistry. As lectures on drinking water concern every human being, the relation with other environmental factors and social relations is also in focus to enable students find mutual influences between different disciplines.
