Filter mainly divided into the following:
PP cotton (polypropylene melt-blown filter):
The use of this filter is usually life of 3 to 6 months, generally do a variety of household water purification equipment, a filter, the tap water pretreatment, filter out water sediment, suspended solids, colloids, organic matter, impurities and so on.
Activated carbon life of 6 months, it is a lot of substances have a strong adsorption, mainly used to remove the water color and smell, chlorine, can change the taste of water. One of the granular filter composition is simple, low cost, but vulnerable to leakage of carbon, life and the effect of instability, commonly used to do a variety of household water purification equipment, two-pole filter. The Ceramic filter
Ceramic filter life of six months to a year, it is formed by diatomite, high temperature sintering and made, and its purification principle and activated carbon similar, but the relative filtering effect is good, long life. 0.1 micron pore size can effectively filter out the water in the sediment, rust iron, some bacteria and parasites and other microorganisms. Filter easy to regenerate, can often brush rinse, sandpaper polished.
UF (ultrafiltration filter)
It is used for three years, the use of polypropylene hollow fiber made in the capillary wall, the distribution of the pore size of 0.1-0.3 micron microporous, able to filter all the bacteria, cut off the water in a very small suspension Substances, colloids, particles, bacteria and other macromolecules, filtered water can drink raw.
RO (reverse osmosis membrane)
RO (reverse osmosis membrane) for three years, it is made of cellulose acetate or aromatic polyamide, its pore size can reach 0.0001 microns, through the high pressure pump, to tap water pressure, the water molecules from the membrane concentration Of the side of the infiltration to the low concentration of the side, and inorganic ions and bacteria, fungi, virions and so can not pass, with the waste water to remove the water in the bacteria, viruses, heavy metals, pesticides and other harmful substances, to achieve direct drinking purposes.
