Introduce several kinds of water treatment filter

1, activated carbon water treatment filter

to a lot of material has a strong adsorption, activated carbon is mainly used to remove the color and odor, residual chlorine in the water, can change the taste of water.

granular filter: basic composition is filling in a particular scaffolding of the granular activated carbon. Composition is simple, low cost, but vulnerable carbon leakage, service life and the effect is not stable, commonly used to do all sorts of household water purification equipment diode filtering. Activated carbon filter: compression than granular activated carbon filtration ability. Longer service life and do all sorts of household water purification equipment commonly used three pole filter. Rear bacteriostatic activated carbon filter: traces of silver ions on activated carbon to upload, do final stage filter, is a few steps further removed filter did not get rid of the impurities or newly introduced, at the same time to kill, to suppress the regeneration of bacteria in water, prevent the secondary pollution of purified water, make water safer.

2, ultrafiltration water treatment filter ( UF)

with polypropylene hollow fiber, are hollow capillary membrane, the membrane wall with aperture is 0. 1 - - 0. 3 micron pores, can filter all of the bacteria, intercept the water of the tiny suspended solids, colloid, macromolecular material such as particles, bacteria, and filter the water can be born after drinking. Can be used repeatedly washing cycle.

3, reverse osmosis water treatment filter membrane filter ( RO)

is the most advanced: RO reverse osmosis. Reverse osmosis membrane made from cellulose acetate or aromatic polyamide, etc, its aperture can reach 0. 0001 microns, through high pressure pumps, to water pressure, the high concentration of water molecules from membrane side penetration of low concentration, and the inorganic ion and bacteria, fungi, viruses cannot pass, along with the waste water discharge, so as to remove the water of bacteria, viruses, heavy metals, pesticides and other harmful substances, can be directly drinkable. Due to ro pure water machine filter of reverse osmosis membrane pore size is very small, easily blocked by impurities and lose, to prolong the service life of ro membrane, must carry on the pp cotton and activated carbon filter, such as pretreatment, reverse osmosis filtration core is common used in the fourth.

4, and other water treatment filter

ion exchange resin filter: can be divided into two categories, cationic resin and anion resin, can respectively with the cations such as calcium, magnesium and sulfate in the water and anion ion exchange, water softening and ion, but it does not filter out bacteria, viruses and other impurities. Heavy metal filter core: such as KDF filter, it is a kind of high purity copper, zinc alloy filter material, which can effectively remove heavy metal ions, and the chemical pollutants such as chlorine, organic matter; Propagation of inhibition of bacteria in water, to prevent the secondary pollution of water, at the same time increase the content of zinc minerals beneficial to human body.
