    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.

    Static thickening tests will be conducted on each distinct sample. The effect of feed solids concentration, flocculant dosage, underflow density and other controllable physical parameters (within flowsheet constraints) will be examined. Compression zone data, important in high rate thickener sizing, is also gleaned from static tests.
