Filter press with alternating diaphragm squeeze chamber plates and filtration chamber plates

摘要

A filter press (10) and method for separating solids from a slurry. The filter press includes a plurality of plates which are held in a sealed and contacting relationship with one another to form a plate stack. The plate stack includes alternating diaphragm-type squeeze plates (68) and cloth-type chamber plates (17) whereby two adjacent plates form a filter chamber therebetween for filtering the slurry. The diaphragm-type squeeze plates (68) include a thin liquid impermeable diaphragm or membrane having a uniform thickness for greater flexibility and heat transfer.
