Planned learning activities and teaching methods
The course uses teaching methods in form of Lecture - 2 teaching hours per week. The e-learning system (LMS Moodle) is available to teachers and students.
Assesment methods and criteria linked to learning outcomes
The exam consists of written and oral parts. Written part consists of two running tests during semester. Results of written tests and oral exam are evaluated.
Language of instruction
1. Waste water sources. Characterisation of wastewater flow and composition. Requirements for wastewater discharge.
2. Wastewater sewerage and sewerage networks.
3. Municipal wastewater treatment lines.
4. Physical and physical-chemical processes of wastewater treatment (mechanical pretreatment, bar racks and screens, grit chambers, primary sedimentation).
5. Hydraulic regime in continuously flow systems.
6. Biological wastewater treatment processes. Classification of processes (ORP, biomass form, reactor configuration).
7. Aerobic wastewater treatment processes. Activated sludge and activated sludge process. Kinetics of microorganisms growth and substrate removal. Kinetic selection of microorganisms.
8. Principal operational parameters. Influence of principal process variables and parameters on treatment efficiency.
9. Biomass and activated sludge mass balance and production. Activated sludge sedimentation characteristics, causes and prevention of sludge bulking. Oxygen requirement and supply.
10. Technological configurations of activated sludge processes. Stabilisation of sludge.
11. Anaerobic biological processes, mechanisms and influencing factors. Granular biomass. Anaerobic wastewater treatment processes. Anaerobic sludge digestion. Anaerobic bioreactors.
12. Nutrient removal from wastewater. Nitrification and denitrification, enhanced biological phosphorus removal. Biochemistry and kinetics of processes. Metabolic selection of microorganisms. Technological modification of nutrient removal processes.
13. Attached biomass systems. Theoretical background of biofilm processes. Kinetics of processes. Trickling filters. Rotating biological contactors. Expanded bed and fluidised bed bioreactors.
14. Treatment, storage and disposal of waste water treatment sludge. Benefits and restrictions of wastewater treatment sludge utilization.
The aim of the course is to get the students acquainted with requirements for quality of discharged waste water, to provide information about sewarage and waste water sewer system, about specification of amount and composition of urban wastewater, about effluent quality requirements, processes and technologies for waste water and sludge treatment.
Specification of controlled education, way of implementation and compensation for absences
Attendance at lectures is recommended, but not monitored. An integral part of teaching and combined form of teaching is a e-learning tutorial course, divided into blocks, within which are available to students learning support including electronic textbooks, presentations, lectures, and other complementary materials.For students in combined form of study are organized consultations to subjec matter. Consultations are also provided to full-time students on request.
