Why can the hepa filter of the vacuum cleaner be washed and the air purifier not work? Different materials,In fact, HEPA can't be washed,The materials of the foreign industrial vacuum cleaner HEPA are mostly blended with glass fiber, polyurethane and other materials,Water washing will have a certain impact on the material,Originally, HEPA did efficient filtering,Washing will reduce the accuracy,Therefore, it is not recommended to wash water (it is not excluded that some HEPA that can be washed is not HEPA at all,BIA certification certificate can be requested for verification ).There is a paper filter for air purification,After washing, it will deform,Lose precision.HEPA precision H14 standard (BIA certification): 0.3 micron filtration efficiency D.O.P99.999%, 0.18 Micron D.O.P99.95%,Compared with the general air purification filter HEPA accuracy is higher.Industrial vacuum cleaners (imported,Nylon bag filter,It is mostly configured on machines that absorb flaky objects and silk (such as special in
Process flow of iron and manganese removal filter The well water of the aeration device enters the aeration device after being pressurized by the self-suction pump,It is mainly to make the well water fully contact with the oxygen in the air;The process of oxidation of low-cost iron ions and low-cost manganese ions in water into high-priced iron ions and high-priced manganese ions and rapidly precipitate.The sedimentation tank reaches the sedimentation tank after oxygen exposure.(It mainly acts as a buffer,Let the water have enough time to precipitate) the precipitated water enters the iron and manganese removal system after being pressurized by the booster pump,It mainly removes sediment, rust, manganese, red worms, algae, some metal substances, various suspended solids and other solid substances in the water,The normal operation conditions of the system are as follows: the operating pressure is 0.3Mpa, the average filtering speed is 15 m/hr.1.When the iron concentration in groundwater is 5 ~ 10 mg/l,The conc
