Belt Filters Solid Liquid Separation

Maintenance. Across the filter, the thickness of the cake may taper in one direction causing uneven cake washing. The alignment across the filter is particularly important for thin cakes since a 0.5% slope on a 2 meter wide belt and a 20 mm cake reduces cake thickness on one side from 20 to 10 mm.

Biosolids Technology Fact Sheet Belt Filter Press

Some belt filter press models separate from the rest of the unit to increase pressure on the biosolids. This produces a drier cake, an important factor for plants that incinerate the final product or face high end use or disposal costs. A biosolids management plan should evaluate the advantages and disadvantages of a high performance belt filter press.
