   pre-filter backwash What is the principle? A look at the introduction of small series now.




is a first pre-filter passage crude whole house water filter device that can filter tap water sediment, rust and large particulate matter, mainly pipes, taps, electrical protection. The following small series will introduce a pre-filter and backwash principle.


backflush filter when the filter works belong in the normal operating state "internal pressure", is to allow permeation of water with its own pressure by the inner wall to the outer wall of the filter, sediment , rust and other impurities are trapped in the particle-tube cleaning when flushing valve is opened so that the filter is trapped impurities are washed away, if they are relatively poor water quality, the user no longer flush, do not worry when the blockage. By backwashing operation switch to the lower portion of the piston, to change the direction of water flow to "external pressure" so embedded in the surface of the filter can not afford cis rushing away impurities.


through these presentations, I believe you know the pre-filter backwash knowledge of the principles of the bar. You also promise that you will ask: home pre-filter must be installed small advice you do not blindly, need to decide according to their own home water quality, water quality standard is actually based on what family does not need to drink small knowledge base?.
