Lesson 11: Sludge Thickening Objective
Sludge must be pre-conditioned with polymer before it is sent to a gravity belt thickener. This conditioned sludge is applied to the belt traveling 2-10 ft/min. This belt speed can vary, depending on the device. Once the sludge is loaded onto the belt, water drains through the belt pores, leaving the dried sludge on the belt surface. This ...
Sludge Thickening
It is widely used in China [7,51] and tends to be the least energy-intensive method of thickening sludge [51]. Water content of thickened sludge is very high (95%), so thickening is generally followed by chemical conditioning and dewatering [7]. Chemical conditioning is a very low-energy process that involves the addition of chemicals to ...
