What impurities are mainly removed from tap water by microfiltration membrane of water purifier?

Microfiltration membrane: Microfiltration membrane removes all kinds of visible objects/dust and impurities from tap water. These particles come from pipeline aging, rust, secondary pollution of roof water tank and so on. The first stage: microfiltration membrane: microfiltration membrane removes all kinds of visible objects/dust and impurities from tap water. These particles come from pipeline aging, rust, secondary pollution of roof water tank and so on. Second stage: compressed carbon: compressed carbon removes chlorine and organic impurities, such as harmful pesticides. It can also absorb the odor, color and smell produced by organic matter in water, which come from disinfection by-products of tap water. The third stage: ultrafiltration membrane: ultrafiltration membrane can remove bacteria, viruses and spores from water. The fourth stage: filter life indicator: the device adopts gear structure design. With the passage of water, the rotation of the gear makes an inner shaft move upward until the water outlet is blocked and the water cannot pass through, that is, the total amount of water passing through the water purifier is calculated through the designed stroke, thus ensuring the safety of the water outlet.
