Well water pre-filter | pure of days | prefilter

Y-type filter backwash filter backwash copper pre-filter (not connected to the pipe by a plurality of valves opening and closing on the formation of recoil and change the flow direction) Principle: When the filter needs to wash the retentate, manual or By automatically adjusting the filter itself comes commutation multi-way valve to achieve reversal of flow, so that the flow of water from the raw water strainer (core) of the water side of the raw water side, to achieve the purpose recoil. Current common pre-filter backwash normal working conditions are "internal pressure" (because this structure is easier to implement multi-valve design), penetration by water pressure from the inner wall of the filter (core) to the wall, sediment, rust and other particles are trapped in the tube-type impurities within the pre-filter maintenance, open the purge valve is trapped by the filter impurities are washed away prefilter home, if they are relatively poor water quality, the consumer is not a long time wash, blocking the filter holes do not worry. By backwash function, then the formation of "external pressure", then embedded in the filter mesh inside (can not afford to be rushing along) pre-filter impurities in well water, it will be washed away. Backwash filter. While addressing the pipeline of secondary pollution problems and new problems have emerged. Because the pipeline corrosion, sediment and other impurities, not only will lead to brown water and water equipment control failure (such as the problem of dripping faucet valve member currently on the market are made proportional valve faucet with ceramic grinding a short piece of fine particles will result in the failure of the valve element lead-piece ceramic valve grinding dripping) and will lead to a heat exchanger pipes get clogged, rupture. Once the pre-filter impurities precipitate in the pipeline, on the one hand provides a breeding ground for bacteria to breed on the other hand will form an electrical compound quality, can cause corrosion or perforated metal pipe in just a few months, backwash front Filters can even solve such problems.
