Solids Thickening in Wastewater Treatment Plants

Solid thickening (sludge thicking) is the important part of the pre-dewatering of wastawater treatment plants. Usually project managers don't give required attention, because of this dewatering machines come up against operational failures.

Solid thickening achives the reduction of the total volume of solids and this gives ease for process.

Nowadays sludge thicking includes gravity belt thickeners, rotary drums, centrifugal thickeners and gravity thickeners.

Primary datas for solid thickening units the following play an important roles;

- Solid loading rate
- Overflow rate
- Underflow solid concentration
- And odor controls
