WHAT IS A FILTER PRESS AND HOW DOES IT WORK?

A filter press is a piece of equipment used in liquid/solid separation. Specifically, the filter press separates the liquids and solids using pressure filtration, wherein a slurry is pumped into the filter press and is dewatered under pressure.

The four main components of a filter press include the frame, filter plates, manifold (piping and valves), and filter cloth, a key ingredient for optimizing filter press operations.

The working principle of filter presses is that slurry is pumped into the machine such that solids are distributed evenly during the fill cycle. Solids build up on the filter cloth, forming the filter cake; the filtrate exits the filter plates through the corner ports into the manifold, yielding clean filtered water.
