Abstract
This is the seventh lecture in the course Water Technology dealing with the activated sludge process used in the secondary treatment of wastewater. This is a PowerPoint lecture which is free to use and modify. It was designed to be used in conjunction with the course text Gray, N.F. (2017) Water Science and Technology: An Introduction, published by CRC Press, Oxford. In the lecture the following are explored: Activated sludge; process control, sludge age, sludge residence time; MLSS; sludge loading rate; f/m ratio; sludge settleability, SSVI, sludge volume index; ecology; filaments; bacteria; filament assessment; bulking; foaming; nitrification; protozoa; ciliates; oxidation ditch; process design; biological nutrient removal; sequencing batch reactors
