1. Experimental purpose:
Activated sludge method is the most widely used aerobic biological treatment method. Many new sewage treatment processes are developed based on the traditional activated sludge method. In the past, they were designed and operated based on empirical data. In recent years, many studies have been done on the dynamics of activated sludge.
