Filter press equipment are sludge dewatering in wastewater treatment plants and mechanical machines which make solid-liquid separation in industrial filtration applications.

The sludge may be pumped to the filter press with high pressure monopomp, piston pump or air diaphragm pumps. A higher rate of dryness is achieved by adding cationic polyelectrolyte to the filter press equipment over the sludge pumped.
