Zakres tematyczny

Lecture programme: Physico-chemical properties of groundwater, surface water and infiltration water. Requirements for water intended for human consumption: microbiological, chemical, radiological, organoleptic and physico-chemical aspects. Technological systems for the treatment of groundwater, surface water and infiltration water. Physical, chemical and biological processes used in technological systems for the treatment of water intended for human consumption. Mechanism of the coagulation process. Coagulants and their properties and effectiveness in removing contaminants from water. Methods of coagulation: volumetric, contact and surface coagulation. Coagulation aids. Removal of suspended solids by sedimentation or flotation. Mechanism of the filtration process. Characteristics of slow and hasty filters. Removal of contaminants in slow and hasty filtration by different filter beds. Adsorbents used in water treatment and their characteristics. Adsorption of organic pollutants on activated carbon. Physical and chemical methods of water deacidification. Removal of iron from groundwater: occurring as inorganic compounds or in combination with organic compounds.  Methods for the removal of manganese from groundwater. Disinfection of water: physical and chemical methods. Side products of disinfection. Causes of secondary water contamination in the distribution system and prevention of secondary water contamination.
Laboratory exercise programme: Selected exercises on: Determination of the physico-chemical composition of raw groundwater, surface water and treated water. Influence of coagulant dose and pH on the efficiency of contaminant removal from water. Removal of micropollutants from water by sorption on activated carbon. Removal of iron and manganese from groundwater by worked bed filtration. Water deacidification.  Water softening. Determination of the length of the filtration cycle.

Programme of design exercises: Technological design of a groundwater and/or surface water treatment station.

Warunki zaliczenia

roject: the basis of obtaining credit is the submission of properly executed project documentation on time, demonstration of knowledge of the unit processes used in water treatment and the principles of designing technological systems for the treatment of groundwater and surface water of a specified pollution degree.

Laboratory: The basis of the assessment is the completion of all laboratory classes provided in the programme, the successful completion of the theoretical knowledge of the classes, and the submission of correctly completed reports on time. The final laboratory grade is the arithmetic mean of the grades obtained from the theoretical knowledge tests in the range of the performed exercises.

Lecture: exam - the prerequisite for taking the exam is a pass mark in the design and laboratory exercises, the exam is in written and/or oral form.Grading scale: Points/Grades obtained: 0 - 50%/ insufficient; 51 - 60%/ sufficient; 61 - 70%/ sufficient plus; 71 - 80%/ good; 81 -90%/ good plus; 91 -100%/ very good.
The basis for determining the final grade is the weighted average obtained by adding: 0.6 of the grade from the lecture, 0.2 of the grade from the laboratory exercises and 0.2 of the grade from the design exercises. The weighted average is rounded to two decimal places. The final grade is determined on the basis of the weighted average according to the rule: below 3.24 - sufficient, from 3.25 to 3.74 - sufficient plus, from 3.75 to 4.24 - good, from 4.25 to 4.74 - good plus, from 4.75 - very good.
