This lecture covers the principles and design of wastewater treatment systems focusing on nutrient removal, including the comparison of different treatment technologies such as activated sludge, biofilters, and moving bed systems. It also discusses the operation modes of the Biostyr biofiltration system, design parameters for filtration rates, and processes for nitrogen removal. The lecture further explores the modernization of a wastewater treatment plant in Bern, Switzerland, detailing the challenges, costs, construction phases, and the chosen treatment processes. Various concepts like Actiflo and Biofiltration are explained, along with the criteria for selecting treatment technologies and the risks involved in the renovation process.
