Pressure Filtration Test Kit

In filter press dewatering, high pressure is directly applied to the sludge against a porous media supported by a plate. Typical pump pressures range from 100 psi to 225 psi. As the pump develops pressure, the sludge is forced onto the media lined plates. The filtrate flows through the media and exit through channels. After a pre-set pressurized time (cycle time), the sludge pump(s) are stopped, the feed line drained, and the press begins to unload. The moving end of the unit retracts and separates the plates, allowing the filter cakes to fall from the plates.
