As we all know, the process of purifying water purifier is to rely on a variety of filter products to achieve. At present, reverse osmosis and ultrafiltration cartridge filter purification equipment on the market is the largest share. Wherein the ultrafiltration membrane can not produce waste water, ultrafiltration water only filter out relatively large molecules harmful substances, does not remove heavy metals and other hazardous substances. So for the relatively poor northern places where the water, RO membrane machine is preferred.
the public to buy a water purifier, it does not waste too much attention to the tail water. In fact, a large part of people do not understand the working principle of water purifier, the installation will not interfere, general installer will draft tube directly into the sewer line along the row away.
