WebGravity thickening may be applicable to activated sludge or combined primary and activated sludge. Polymer or other flocculants are generally used in such cases to improve thickening. Dissolved air flotation is generally used for waste activated sludge. Polymers are often used to improve solids capture and degree of solids concentration. WebGravity Belt Thickening. 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 ...

WebThe Flottweg OSE decanter is specially designed for sludge thickening. This enables them to achieve better performance than comparable units. A special scroll design with deep pond and steep cone increases the sedimentation volume in the decanter bowl. This enables a higher output density (10 - 20 percent) and makes the system more efficient.
