Biosolids Technology Fact Sheet Gravity Thickening

Gravity thickener designs usually include circular tanks, 3-4 m (10-13 ft) deep and up to 25 m (82 ft) in diameter. The dimensions are based on prediction of settling due to gravity alone. To assist solids transport, gravity thickener bottoms are constructed with a floor slope between 1:6 and 1:3.

🚧 Sludge treatment − gravity belt thickening Sludge ...

Jun 18, 2020  How gravity belt thickening works. Gravity belt thickening (GBT) increases the sludge solids concentration (i.e. thickens the sludge) by allowing the water (or filtrate) to drain from the sludge under gravity through a permeable medium (a moving belt) on which the sludge sits.. There are two types of belt-based processes for increasing sludge solids concentration.
