When the electricity does not work, can the water in the water filter be drunk?
4, reverse osmosis filtering aperture in 0.0001-0.001 micron range, typical application of reverse osmosis membrane, the ion can be filtered out, only water molecules to pass through, but need more energy consumption, waste water; drinking water machine sold on the market are generally ultrafiltration and reverse osmosis machine machine, ceramic machine, have different characteristics, can be purchased according to your needs: 1, whole house water purification: buy ultrafiltration machine, low cost, no energy consumption, long service life, purification of large amount of activated carbon after drinking; 2, drinking: suggested using reverse osmosis machine, but the need for power pressure, wastewater accounted for 7 into.
Can be divided into: 1, 0.2-20: microfiltration filter aperture in the micrometer range, a typical application of PP cotton, activated carbon, can filter sediment, algae and bacteria; 2, ultrafiltration: filter aperture in 0.005-0.2 micron range, particularly pressure and internal pressure of two, typical applications of PP film, PVDF film, PS film. Can filter most viruses, including microfiltration, organic matter; ultrafiltration membrane is a new material, is widely used in the water treatment industry, in particular PVDF (polyvinylidene fluoride) ultrafiltration membrane with strong acid and alkali resistance, aging resistance, large flux and easy cleaning features, 3, nano filter: filter aperture in 0.001-0.02 a typical application of micrometers, PP cotton, activated carbon, can filter most of the organic matters
Can refer to, depending on your filter is what kind of filtering method, if it is reverse osmosis, no longer straight drink, need to boilCurrently on the market a variety of water filter is various, like PP cotton, activated carbon, ultrafiltration, reverse osmosis, ceramics etc., can effectively filter the impurities and bacteria, water and minerals, the filtering process of professional knowledge is more complex, I tell you to do a presentation, in fact, according to the classification of aperture,
