What is a Filter Press? 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

Filter Press Pilot Testing Guidlines Introduction The goal of filter press pilot testing is to collect the data required to accurately size a full scale filter press system Typical data collected includes cake solids, cake density, total processing time, if desired filtrate suspended solids, slurry feed solids, slurry pH, actual chemical conditioning dosages, and maximum operating pressure

Filter presses use air to control the hydraulic opening and closing and for the air blowdown sequence Since air is already used during these processes, an air operated diaphragm pump is the best choice to operate a filter press

Tube presses The Tube Press, because of its unique design, will automatically and economically dewater most slurries to produce a clear filtrate No thermal drying needed making this hard, surface dry cake convenient to handle for immediate storage or for disposal
