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. |
