WebA GRAVITY THICKENING Lesson Descriptian This Tesson deals with the basic operation of the gravity thickener. It covers the theory of operation and describes the comonents found in a typical thickener. Consideration is then given to the parametei-s which must be understood in optimizing the operation of the thickener. AttentiOn Webbatch processes. Gravity thickeners are essentially settling tanks with or without mechanical thickening devices (picket fence type). Plain settling tanks can produce solids contents in sludges of up to 8.0 percent for primary sludges and up to 2.2 percent for activated sludge. Activated sludge can also be concentrated by resettling in primary chris litchford
