WebbThe thickening tank is equipped with slowly moving vertical paddles built like a picket fence. Sludge is usually pumped continuously from the settling tank to the thickener … Webbbatch 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 ...
