The technology of tap water filtration in our country mainly depends on bleaching powder. Although it has good bactericidal effect, bleaching powder itself is accompanied by some toxic substances. When filtering tap water, there will be some residual substances, which gradually form residual chlorine as we know. Residual chlorine will be detected in domestic tap water. I believe that many families have deeply realized it and let us understand the filtering effect of sewer.
Can the water purifier effectively filter residual chlorine in tap water? What technology does the water purifier use to filter out residual chlorine in tap water? What technology can remove chlorine from tap water?
The first PP cotton filter core and the third compressed carbon filter core adopt the plugging and decontamination technology, and plug the pollutants larger than the filter core pore size in tap water by setting the filter core pore size; however, the residual chlorine and water molecules are closely integrated, and the removal effect of conventional filter core is not good.
The second and fifth stages of activated carbon filters adopt the principle of adsorption and filtration. Through the adsorption of activated carbon, the odor of different colours in water can be removed, which can improve the irritating odor of residual chlorine to a certain extent. This is only to remove odor, but also to remove a small part of residual chlorine, which can not be completely purified.
The four-stage ultrafiltration membrane is the most precise filter element in the water purifier. Its pore size is 0.01 micron. It has a good barrier effect on residual chlorine in tap water larger than the pore size of the membrane. However, some residual chlorine may be less dense than the pore size of ultrafiltration membranes, which can not achieve the effect of complete purification.
Regarding the way of removing residual chlorine from tap water, the neutralization system considers that the reverse osmosis membrane in the water purifier has a good purification effect, and the reverse osmosis membrane adopts the reverse osmosis water purification technology. The pore size is 0.001 micron, 10 times thinner than UF membrane, and the decontamination rate is over 95%. It can completely remove residual chlorine in tap water.
