The process uses the principle of pressure drive, as provided by a slurry pump. Among other uses, filter presses are utilized in marble factories in order to separate water from mud in order to reuse the water during the marble cutting process.Sewage treatment - WikipediaSewage treatment is the process of removing contaminants from municipal wastewater, containing mainly household sewage plus some industrial wastewater. Physical, chemical, and biological processes are used to remove contaminants and produce treated wastewater that is safe enough for release into the environment. A by-product of sewage treatment is a semi-solid waste or slurry, called sewage sludge. The sludge has to undergo further treatment Some results are removed in response to a notice of local law requirement. For more information, please see here.
Dewatering Sludge Through a Filter Press Helps Eliminate , how a sewage treatment filter press works
Based on these results, Rocco's management elected to purchase a 1200mm recessed chamber filter press to dewater the sludge generated by the chemical treatment of their average wastewater flow of 750,000 gpd.

The machine runs continuously, with a high degree of automation, energy saving, high efficiency, and maintenance.Industrial Wastewater - Belt Presses - Hydroflux IndustrialBelt Presses. The belt press works by introducing flocculated sludge into a gravity zone where free water is allowed to drain thus reducing the volume of slurry to be dewatered. This thickened slurry is then squeezed between 2 belts under high pressure to produce a spadable cake. In industrial applications, a belt filter press will generally, how a sewage treatment filter press works

Filter presses operate on feed pressure and can be used for high volume separation of solids from slurries, utilizing recessed or membrane plates. When the wastewater passes through the filter plates the discharge system and the filter medium retain the solid particulates.
The system of the filter is designed with an internal fitting done with an inlet distributor and bottom collecting system while the external fitting is done with isolation valves and frontal pipe work. Working of the filter is processed with the activities performed by the sand and the anthracite wherein sand removes the suspended particles and the odor and color is removed with the help of anthracite.Sludge Dewatering Equipment - Wastewater Treatment PlantFilter presses are used for sludge dewatering in wastewater treatment plants. The sediment has minimal humidity after passing through the filter press, which simplifies its disposal. There are filter presses of various designs: frame, chamber vertical and horizontal, band, drum, screw (auger).How Does Sewage Treatment Work? - Scientific American
