In recent years, accidents of urban sudden water pollution in China are frequent, drinking water safety crisis frequency, people are increasingly concerned about drinking water, and reverse osmosis pure water machine and ultrafiltration membrane water purifier for people to provide high quality drink and gradually by everyone's attention, but reverse osmosis water purifier and ultrafiltration membrane purification machine still have some differences.
The difference of filtration mechanism
Reverse osmosis pure water machine is using reverse osmosis membrane filtration technology, the ph value of its production is lower than the ph value of influent. The reverse osmosis membrane is the selective permeation membrane that removes all the heavy metal ions that dissolve in the water that are harmful to the human body, can also remove other ions dissolved in water, as well as the maximum removal of dissolved and water carbon tetrachloride, chloroform and other harmful organic matter to the human body, water molecules in the original water is retained for drinking, Other including bacteria, viruses, pollutants, scale, etc. have become concentrated water discharged, such as water into the human body, the human body can absorb is retained, can not be absorbed with the urine was discharged in vitro. Therefore, reverse osmosis pure water machine has "in vitro kidney" reputation.
