What are the three stages of filter element of water purifier

1 polypropylene melt blown filter element (ppcotton)
It is often used for one pole filtration of various domestic water purification equipment, pretreatment of tap water, filtration of sediment, suspended matter, colloid, organic matter, impurities, etc.
2 active carbon filter element
Activated carbon has a strong adsorption on many substances, mainly used to remove the color and odor of water, residual chlorine, can change the taste of water.
Granular filter element: the basic composition is the granular activated carbon filled in a specific support. The utility model has the advantages of simple composition, low cost, easy damage and carbon leakage, unstable service life and effect, and is commonly used for the two pole filtration of various household water purification equipment,.
Compressed activated carbon filter element: better than granular activated carbon. The utility model has longer service life and is commonly used for three pole filtration of various household water purification equipment.
Post bacteriostatic active carbon filter element: a micro amount of silver ion is added to the active carbon, which is often used as the final filter element to further remove the impurities not removed or newly introduced in the previous steps of filtration, kill and inhibit the regeneration of bacteria in the water, prevent the secondary pollution of purified water, and make drinking water safer.
3 ceramic filter element
Ceramic filter element is made of diatomite by molding and sintering at high temperature. Its purification principle is similar to that of activated carbon, but it has good relative filtration effect and long service life. The pore size of 0.1 μ M can effectively filter the sediment, rust iron, some bacteria and parasites in the water. The filter element is easy to regenerate. It can be washed with a brush and polished with sandpaper.
