Gravity Thickening Factsheet - US EPA

2021-6-25 · Nearly static conditions are required in gravity thickening tanks in order to induce settlement. Therefore, the tank design must ensure a smooth, continuous flow of liquid at the center well, the weirs, and the solids removal point. Gravity thickener designs usually include circular tanks, 3-4 m (10-13 ft) deep and up to 25 m (82 ft) in diameter.
