Course objectives

Knowledge of advanced water treatment processes for high standards of effluent quality and natural purification processes in rural areas.

Course enrolment requirements and entry competences required for the course

Passed a subject dealt with classical processes of water treatment (Wastewater treatment and / or Industry and Environment)

Learning outcomes expected at the level of the course (4 to 10 learning outcomes)

It is expected that the outcome of learning to provide knowledge about:
- the necessity of the development and application of advanced water treatment processes, with special emphasis on the protection of vulnerable karst aquifer
- types of process, application and advantages of the application of advanced process compared to conventional treatment processes
- analysis of the ecological footprint water treatment facilities
- advanced oxidation technologies in water treatment
- chemical reactions and reaction mechanisms of hydroxyl radicals
- mechanism, kinetics and the performance of the adsorption and ion exchange in water treatment
- biological processes of removing nitrogen and phosphorus, technological performances, removal efficiency
- the application of MBR technology in water treatment and comparison of membrane bioreactor technology with other technologies for biological treatment of wastewater
