Mechanical filter (Quartz sand filter)

Mechanical filter is also called quartz sand filter or pressure typr filter Application Pretreatment of ion-exchanger and desalination system. Pre-filtration in RO system. Filtration of civil life water, sewage and waste water of industry Coarse filtration of feeding water in industry and pool water. Features Reasonable structure Anti-corrosion: Epoxy resin inside and outside to avoid .pollution Easy for using and repairing Types (method of inlet water ) Uniflow type: water flows from top to bottom. Double flow type: water flows in both from top and bottom, flows out from middle outlet. Working principle membrane filtration— Osmosis filtration— Contact coagulate— other procedures.
