The role of filter element in pure water machine and installation design profile - 【 3 m filter.

Filter determines the output water quality of pure water machine, pure water machine, the choose and buy must pay attention to the filter shows effectiveness in filtered water. The pure water machine technology most using activated carbon filter filter, microporous ceramic filter, membrane separation, etc. But with the increase of using time, filter the ability to work with the processing of water decreases, you need to change in time filter.

ceramic filter purification principle and similar to that of activated carbon, but relatively good filtering effect, long service life, but also can't completely in addition to bacteria, etc. Membrane separation filter type, mainly include microfiltration, ultrafiltration, such as fine filtration and reverse osmosis process.

ultrapure water machine filter technology introduce

1, 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.

triple filter before pure water machine is do pretreatment for reverse osmosis membrane, as the pretreatment of raw water, in order to increase the service life of reverse osmosis membrane, reverse osmosis membrane so pure water machine before a filter or 1 & mu; MPP cotton is better.
