pre-filter What is the role? I believe many people know, it is to remove large particulate matter.
As the pre-filter water treatment technology in general can not and water purifier, water softener compared to so many people feel no need to install a pre-filter. The fact is it really? How to install a pre-filter What is the role of it?
First, solve the problem of secondary pollution
for urban water supply pipelines, because the use of time are generally more long, so are older, more pipeline sediment, rust and other impurities, water will flow through a certain amount of pollution. And the prefilter filtration accuracy of about 5-100 microns, can be filtered out as sediment, rust and large particles of suspended matter and other impurities, can help prolong the life of the device associated water.
Second, to reduce scale and corrosion of pipes
prefilter may prevent calcium and magnesium ions combine with carbonate ions so that generation of scale may function to soften water. In addition, pre-filter may also form a protective film on ecological inner wall of the tank, to prevent corrosion of the pipe wall and repair.
Third, the protection device downstream of the water
As a first pre-filter filtration apparatus, may function to protect the downstream water purifiers and other devices can be used instead PP cotton that require frequent replacement of the pre-processor, to become a more robust pre-pre-processor device.
through these presentations, I believe you know the pre-filter What is the role of the knowledge of it. You also promise that you will ask: home pre-filter must be installed small advice you do not blindly, need to decide according to their own home water quality, water quality standard is actually based on what family does not need to drink small knowledge base?.
