There are several factors that will affect the operation of the gravity thickener, including: the type of sludge being treated. Gravity thickeners can only be used on primary sludge, since secondary sludge doesn't settle well due to the high water content. sludge age. Older sludge will denitrify (remove nitrogen) and cause settling issues.

This is more than four times the rate typically used for conventional clarifiers. In addition, the CONTRAFAST unit produces sludge with as much as 10% solids by weight, eliminating the need for a gravity thickener. The combination of the high rise rate and the elimination of the separate thickener reduces the total process footprint.

Laboratory testing with a high rate thickener has shown the importance of feed solids control to thickener and flocculant performance (Table 4). In the preoxidation as well as CCD thickeners, testing has demonstrated that an optimum feed solids level can be attained which will maximize thickener performance while minimizing flocculant consumption.
