Multi-medium FilterOverview:It is always a pretreatment device for raw water in water treatment system. The multi-medium filter which is a medium filter uses two or more mediums as filtering layer is used to remove impurities and adsorbed oil in sewage in industrial circulating water treatment system to make the water quality meets the requirements of recycling. The filtering with the main function of removing suspended and colloidal impurities can efficiently remove tiny particles and bacteria which cannot be removed by precipitation technology,Website:http://www.dhpetrotools.com, and give a certain level of removal efficiency on BOD and COD.Operating principle:Multi-medium filter mainly utilizes one or more filtering mediums to remove suspended particles and mechanical impurities in water for reduction of the effluent turbidity by making water through the mediums under certain pressure. The effluent turbidity can be under 3° if the influent turbidity is under 20° in general case.It is used to remove the suspended and solid particles in water. Suspended solids are colloidal solid materials that do not dissolve in water, and they may precipitate at the suitable conditions. When the filter is intercepting suspended solids, the weight difference before and after the interception by filtering medium is deemed as the basis for measuring the filter function. The single-layer, double-layer and multi-layer filtering can be adopted according to the impurities in water that could meet the quality requirements of deep purification.Scope of Application:  1.Pretreatment for systems of reverse osmosis, electrodialysis, ion exchange and ultrafiltration;  2.Preliminary filtration treatment on raw water of power generation, chemical industry, papermaking and beverage;  3.Decolonization and removal of organic matter for water supply of chemical plant;  4.Pretreatment on domestic water;  5.Industrial water treatment, removal of suspended particles and solids in industrial sewage;  6.Swimming pool water treatment;  7.Circulating water bypass filtering system;  8.Turbidity lowering and color removal;  9.Wastewater treatment;10.Softening of ion exchange method and pretreatment equipment for desalination system, as well as equipment for swimming pool circulating treatment system and cooling circulating water purification system.Technical parameters:  Main technical parameters:  Working pressure: 0.1MPa~0.6MPa  Working temperature: 5℃~90℃ (custom-made for special temperature)  Unit discharge: 0.5m/h~125m/h  Operation mode: manual or automated control  Product specification: ф167~ф3200  Filtering rate: 5m/h~12m/h, max.15m/h  Simplified materials: 304, 316L, Q235 rubber lining or epoxy painting  Tank selection (reference flow with tap water as the filtering medium)Specifications and Models:specificationsCodesc-7sc-15sc-30sc-45sc-49sc-70sc-80Water yield (T/H)7153045497080Access hole DN0450450500500500500500Inlet water DN180100125125125150150Outlet water DN280100125125125150150Backwash entering DN380100125125150200200Backwash discharge DN480100125125150200200Wash discharge DN580100125125125150150H2880347036104020402043804450H02080260026103040304033803450H1150150190190190220220H2800800800800800800800H31100120012001300130014101410H41160131014601590159016201620L1629.5870882.51032.51032.51178.51280L2750100012551500150017501920L33505608101100115013501450Ф1000150020002400250030003200Ф1985135018602250236028203100M180180250300350400400N125140200300300350350Weight (kg)910195028354838521277568216
