Belt Press Filter Test Kit

Pretreated (chemically conditioned) feed sludge is introduced to the gravity drain deck where furrowing plows move the sludge to allow free water to drain. As the sludge travels along the belt filter, the sludge is fed into a low pressure wedge zone where the sludge is trapped between the upper and lower belts. As the belts converge on the initial contact point of the first pressure roll, the sludge is dewatered by the increased pressure. Final dewatering occurs in the high pressure zone as the trapped sludge travels through a series of smaller diameter rollers with sharp turns.
