Students will be able to: apply basic microbniological and biochemical principles together with the knowledge of reactor engineering to the description of biological wastewater treatment and reactors used for the treatment; put together flow scheme of wastewater treatment plant; uderstand basic arrangements of activated sludge processs for organic pollution removal, nitrification and denitrification and phosphorus removal, both biological and chemical; define and calculate basic technological parameters of activated sludge process for its control and design; find proper control measures for activated sludge separation problems and aply this knowledge also for construction and design of secondary clarifiers. design processes of tertiary treatment for different purposes of wastewater reuse |
