Filter Press

A Filter Press is a highly efficient, compact, dewatering device for separating solids from liquid slurries in the form of compressed cake. Its major components are a structured framework, filter chambers (formed by recess portion of Recessed plate system, or frames in plate and frame system), and filter cloth.
Filter Press technology although very basic in nature, but its application is as important to the various processes it serves, as is a simple wheel to the motive machines. Filter Press are separation devices used for solid or liquid separation that work on feed pressure or squeeze pressure to reduce liquid content in process or waste slurries or to reduce solid content in a product.
A Filter Press consists of a series of horizontally arranged vertical filter elements (Filter Plates in recessed plate system, or plates and frames arranged in 1232 sequence, in plate and frame system), each covered with paper, felt medium or synthetic woven material. A mechanical structure called skeleton is used to support the Filter Plates and a closure mechanism provides the required force on the sealing faces of the plates to counteract the applied force of filtration(squeezing).
The hydraulic cylinder controlling the follower plate presses the plates together creating a sealed unit. Each face of each plate is covered with a filter medium to form a series of perforated chambers into which process material is introduced under pressure.
