Selection criteria - pure water machine in the filter 【 3 m filter.

Pure water mechanism of pure water relative to the bottled water is more fresh, more health, more security, it has a very wide range of USES, can drink, also can bring to a boil water, in this outstanding characteristic is the kettle or electric thermos would never 'scale; Convenience of pure water for cooking, more health, more delicious; Wash in pure water, can remove impurities in the skin, moisturize skin, have the effect of the natural beauty; Can be provided to the humidifier, steam iron, hairdressing instrument required for small home appliance such as water, never appear, let people hate white powder; With ice machine, made of ice crystal clear, no peculiar smell.
now standard pure water machine configuration is commonly 5:5 & mu; MPP cotton - - Granular activated carbon - - 1μ MPP cotton - - - - - - - RO membrane - - - - - - - After the activated carbon. Some manufacturers and this is the third level configuration to block compression or sintering CTO of activated carbon, the third level filter is 1 & mu; MPP cotton good or block compression is suitable for activated carbon?
it is well known that the former triple filter is in the service of the RO membrane, as the pretreatment of raw water, in order to increase the service life of RO membrane, the pure water machine of RO membrane before a filter or 1 & mu; MPP cotton is better.
for three reasons:
a, can effectively prevent internal activated carbon powder into the RO membrane, protect the RO membrane decrease as far as possible the entry of activated carbon powder, prolong its service life. Because before installing the activated carbon filter we wash and clean, also can have charcoal powder flow out, before the RO membrane with a 1 & mu; M filter can have barrier effect, greatly reducing the possibility of man-made pollution of RO membrane.
2, 1 & mu; MPP cotton is 1 micron filtration precision, greater than 1 & mu; M of sediment particles, bacteria, scale and other harmful substances can roundly eliminate, in the first 5 & mu; M still can rise to protect the RO membrane filter loss effect, reducing the probability of RO membrane contaminated.
3, if the third level is the massive compression or sintering CTO of activated carbon, five three filter is activated carbon filter, activated carbon filter for repeated use, not only waste resources, also increase the cost and lose its proper role.
and the second level is generally granular activated carbon, installation time need to wash, often cause a lot of blackwater, and easy to wipe clean. If activated carbon to compress the blackwater problem is solved, does not increase the burden of the third grade PP cotton.
raw water by the three leading preprocessing filter filter. The first level PPF 5 micron filter, purify water, greater than 5 micron suspended solids and other substances. 2 granular activated carbon adsorption odor of raw water, chlorine and chlorine byproducts such as organic matter.
3 1 micron PPF removing water is greater than 1 micron suspended solids and other substances. After three pretreatment of water, into the high-pressure pump pressurized into 4 reverse osmosis membrane, as a result of the reverse osmosis membrane aperture only 0. 0001 microns, & ndash; Shrink to four thousand times more bacteria, and infectious virus will shrink more than 200 times to pass, so all the subtle impure water impurities, soluble solids, bacteria and viruses can not seep through high-precision reverse osmosis membrane. Reverse osmosis membrane separation, water and other impurities and pollutants pests by thick shuikou automatic discharge, water pressure within the barrel to spare. When water open gooseneck faucet water after the first five bacteriostatic activated automatically outflow can be safe to drink.
