The plate and frame filter press is the most fundamental filter press design, and it has been in use since around 1850. This type of filter press consists of many plates and frames assembled alternately with the supports of a pair of rails. Plates and frames were made of wood and metal until the mid-1900’s when thermal plastic plates were introduced into the market.
The filtrate that passes through filter cloth is collected through collection pipes and stored in the filter tank. Filter cake (suspended solid) accumulation occurs at the hollow frame and is separated at the filter plates by pulling the plate and frame filter press apart. The cakes then fall from those plates and are discharged to the final collection point.
Filterfab manufactures cloths for a plate and frame press in a single piece.
