medium. The diaphragm filter press operates like a recessed plate press, at pressures between 690-1,040 kPA (100-225psi) (USEPA, 1987). However, higher pressure is achieved by expanding the diaphragms, reducing the volume of the chamber by squeezing out more water. Diaphragm filter presses often result in a cake with a higher solids content.

Filter Press Diaphragm Pumps | Buy New Pumps from Met-Chem

Air operated diaphragm pumps are used with filter presses to pump sludge from the bottom of the sludge holding tank into the filter press. These pumps are ideal because they can handle the slurry which is generally about the consistency of a milkshake. The diaphragm pump usually starts out slowly and gradually ramps up. Once the pump starts to slow back down, (30-60 seconds between thrusts ...

Filter Presses

Another common use for a filter press is as a "variable volume" filter that uses a filter plate known as a diaphragm or membrane plate. This type of plate has a flexible drain-field which when sealed around the edges forms an integral bladder or diaphragm that may be inflated to physically press additional liquid from the filter cake.
