Water purification machine - filter configuration requirements 【 3 m filter.

Now the standard water purification machine for five commonly configuration: 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?

the filters filter is the filter contaminated water to clean to the status of production, life need, also is to make the water reaches a certain cleanliness. Remove the solid particles in the water and kill bacteria, filtering harmful chemical composition.

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 water purification machine of RO membrane before a filter or 1 & mu; MPP cotton is better.

here's why:

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.
