Clarification Failure Control Strategies
Publication: Journal of the Environmental Engineering Division
Volume 108, Issue 6
Abstract
Two solids inventory control strategies for prevention of clarification failure in the activated sludge process are considered. Recycle rate control is shown to be effective for a certain class of operational situations. This control algorithm, however, is not applicable to situations in which an activated sludge system is experiencing severe hydraulic surges. In such situations clarification failure can be effectively controlled only through the application of the step-feed strategy in which the location of the feed to the aeration basin is shifted downstream in a multipass basin.
