Description
This class will discuss the science and math behind the three principles guiding the control of the activated sludge process: (1) give the mixed liquor just the air it needs, where it needs it, when it needs it; (2) identify and maintain the minimum SRT TARGET that meets the effluent ammonia requirement and gives the best sludge quality; and (3) maintain the lowest RAS flow possible without overloading the secondary clarifier.
