Syllabus of lectures:

Water Quality

1. Use of water and requirements for its quality. Natural composition of surface freshwaters - cycles of basic elements, processes and natural factors.

2. Water pollution I - types of pollution, their properties and effects (pollution causing oxygen depletion, nutrients, suspended solids, toxic substances, plastics)

3. Water pollution II - types of pollution, their properties and effects (water acidification, thermal pollution, pathogenic microorganisms, pollution affecting organoleptic properties)

4. Sources of pollution - point and non-point sources, sources related to surface runoff, accidents

5. Lakes and reservoirs - ecosystem, stratification, eutrophication, modelling, protection measures

6. Special lecture on humic substances and manipulation with drinking water reservoirs

7. Special lecture on eutrophication and biomanipulation of reservoirs

8. Streams and rivers - ecosystem, self-purification, modelling of transport and transformation processes, protection measures

9. Measurement and monitoring of water quality - temporal and spatial aspects, physical-chemical monitoring, biomonitoring, hydromorphological monitoring. Classification of surface water quality in the Czech Republic.

10. Special lecture on micropollutants as a new type of pollution

11. Legislative approaches to water protection – EU and Czech legislation

12. Field trip Biomonitoring of streams

13. Conclusions and Discussion

Water Management:

1. Legislation, history of water treatment, water sources, water quality

2. Water treatment methods, design of water treatment plant

3. Treatment of groundwater – CO2 removal, iron and manganese removal, filtration, disinfection, ion exchange

4. Treatment of surface water - mechanical pre -treatment, preoxidation, disinfection

5. Treatment of surface water - clarification, dissolved air flotation

6. Treatment of surface water - filtration, adsorption, stabilization, membrane processes, sludge management

7. Water demand - calculation

8. Pump stations

9. Water tanks - functions, calculation, pressure zones

10. Distribution of water - design parameters and requirements

11. Distribution of water - pipe materials, fittings, constructions

12. Distribution of water - maintenance

13. Conclusions and Discussion

Syllabus of tutorials:

Water Quality:

1. Characterization of the chemical composition of waters.

2. Mass balances, substance transformation. Rivers - transformation of pollution.

3. Rivers - transport of pollution: tracer, pulse.

Water Management:

1. Evaluation of the pumping test

2. Design of pressure zones

3. Design of the discharge system

Study Objective:

Water Quality: The goals of the study are to understand natural processes and human influences on the quality of surface waters and to master the basics of water quality modelling.

Water Management: The goals of the study are to understand drinking water treatment processes and and the issue of drinking water distribution from the source to the consumers.
