backwashing strainer

Introduction
The ABWF back-washing filter is make up of housing, multi-filter element , back-washing mechanism , electric control box , motor , electric sewage valves and pressure control , pressure relief valve , exhaust valve . Diaphragm within the shell cavity is divided into the two cavities , the cavity is equipped with multiple filter , so that full use of the filter space , significantly reducing the volume of the filter and lower cavity installation of backwash arm and backwash whipsaw . The filter uses a unique backwash design , use main pipe water pressure to backwash , no need to set up a dedicated backwash water , can ensure the machine working non-stop .
backwashing strainer

Use cope:
- An industrial circulating water filtration---water quality equipment such as : cooling towers , rolling mill , continuous casting machine , polishing machine , electric ion exchange , sprayers , heat exchangers , etc . for the drain pipe on the road can be filter out impurities in the water , to prevent parts congestion .
- The original water treatment---filter to remove sand , bacteria , algae , organic matter and so on the surface of the river , lake , reservoir water , well water and groundwater , water filtration for boiler wet dust , for the water filter .
- The cooling water treatment---cooling towers , add water systems , air conditioning system , DC system water filtration , to reduce the generation of sediment in the heat exchanger , to maintain its cooling effect , power plant turbine cooling .
- Such as metallurgy , petrochemical , food and pharmaceutical industries---liquid industrial waste water has been emulsion regeneration and used oil filter processing : casting water , blast furnace , water system , hot-rolled high pressure phosphorus removal system .
- Paper making industry---white water filtration
- Plastics industry---recycling cooling water filter
