Film water purifier 5 can remove organic matter and coloration in water, remove the hardness of water, part removes dissolubility salt, by NF membrane
Water purifier 5(Nanofiltration is a kind of screening process using membrane separation technique, using the pressure difference of film both sides as driving force, with NF membrane
For filter medium, under pressure, when stoste flows through film surface, the densely covered many tiny micropores of nanofiltration film surface are only
Allow water and small-molecule substance by by become permeate, and volume is more than the substance of film surface micropore diameter and is then trapped in stoste
In the liquid feeding side of film, become concentrate, thus realizes the purpose to the purification of stoste, separation and concentration)Treated, and moisture is
Concentrated water and clear water, concentrated water are entered by diversion pipe 22 in waste water tank 8, and clear water enters anti-penetration water purifier 6 by conduit(Its work
It is to apply certain pressure to water as principle, hydrone and the mineral matter element of ionic state is made to pass through reverse osmosis membrane, and is dissolved in
Most inorganic salts (including heavy metal) in water, organic matter and bacterium, virus etc. can not penetrate reverse osmosis membrane, to make
The pure water that the penetrates and condensed water that can not be penetrated is stringent separates)In, after being handled by anti-penetration water purifier 6, it can incite somebody to action
Salt ion in water is sloughed, and the rate of sloughing is up to 98 percent, since ultrasonic humidifier 7 wants water in the process used
It asks very high, if the calcium and magnesium plasma contained in fruit water is excessive, is susceptible to humidifier white powder phenomenon(Humidifier white powder phenomenon is exactly
Since water accumulates a kind of phenomenon to be formed by the calcium ions and magnesium ions after 1-5 microns in water are broken into)Over time, equipment can be influenced
Service life, therefore the calcium and magnesium plasma in water removal is removed with nanofiltration membrane water purifier 5 and anti-penetration water purifier 6, while can also remove it
