Water treatment
Forms and semester of classes: Lecture 15 hours, Laboratory Exercises 30 hours, 5th semester (winter).
Program contents:
Principles of sustainable water management; quality requirements that water supplied to consumers should meet. Physicochemical parameters of water as characteristics of quality water: transparent, colorless, odorless, pleasant and refreshing taste, must not contain pathogenic bacteria and excessive amounts of manganese, iron, chlorides, nitrates, nitrites, sulfates and calcium. Water treatment processes: physical, chemical and biological, aimed at, among other things: removing iron and manganese compounds, softening, improving taste and sanitizing. Unit processes used for water treatment: aeration, coagulation, sedimentation, flotation, filtration, straining, ion exchange, chemical precipitation, sorption on activated carbon, chemical oxidation, membrane processes, disinfection, infiltration, etc. Secondary water pollution.
Issues of laboratory exercises:
Selected water treatment processes to demonstrate the course and conditions of the process and determine the content of selected water quality parameters by analytical method after the experiment. Exercises include the following processes: removal of iron compounds from water by physicochemical method; water treatment by reverse osmosis; removal of phosphorus compounds by volumetric coagulation; removal of water hardness by ion exchange; advanced methods of oxidation of organic pollutants; disinfection of water.
