Description

This lecture covers the biological processes involved in nutrient removal in wastewater treatment plants, including denitrification and phosphate removal. It discusses the implementation of denitrification using organic matter and the importance of carbon sources. The lecture also explores biological phosphate removal methods, such as the A/O process and the PhoStrip process. Additionally, it delves into the chemical phosphorous removal process using coagulants like iron chloride and aluminum sulfate. The dimensioning of biological reactors for activated sludge systems with nitrification, denitrification, and chemical dephosphatation is also explained, focusing on sludge age, specific sludge production, and safety factors for nitrification.
