【Introduction】
Multi-media filter refers to the use of different size layers of quartz sand, anthracite, or ceramic filter media, such as equipment, mainly used to remove silt, suspended solids, humic substances, colloidal and other large particulate impurities. Pass filter is a multi-media filter bed, suspended solids removal flakes cohesion and precipitation can not remove the adhesive resin material. Mainly used for softening, desalination, water pretreatment system is also used as a less demanding industrial water supply rough filtering. The situation by using the filter, mechanical filter can be divided into single-and dual-media filter devices and control multi-media devices. Dual-media device for the raw water turbidity of less than 60mg / L of sediment water filter, filter device used only as a single raw water turbidity of less than 15mg / L of sediment water filtration. Mechanical filter effluent turbidity control in general 3mg / L or less.

【Applications】
Multi-media filters, mechanical filters, according to the type of control can be divided into manual-and automatic-type, press materials can be divided into the glass tank steel cans, steel cans, steel cans, tin wall required to do according to the epoxy used Anti-corrosion coating or rubber lining.
