The course is designed to provide undergraduate students in Environmental Engineering with the necessary background for a meaningful understanding of the general principles of wastewater treatment. The course provides a quick overview of the basic concepts of aqueous chemistry (concentration units, chemical equilibrium, reaction rate, chemical kinetics, chemical thermodynamics) and examines in depth: Wastewater quality characteristics (Quality of untreated wastewater, Organic chemical characteristics, Theoretical determination of oxygen demand, Biochemical oxygen demand, BOD measurement methods), Wastewater treatment processes (Basic processes, Selection of processes, Primary treatment, Sedimentation), Biological treatment of wastewater (Principles of microbiology, Microorganisms growth, Activated sludge systems, Ventilation reservoirs, Oxygen mass transfer, Operational problems, Secondary sedimentation tank design), Biofilm reactors (Trickling filters, Rotating biological contactors), Biological removal of nutrients (nitrification, denitrification, biological removal of phosphorus), disinfection of treated wastewater (disinfectants, chlorination, ozonation, UV).
