What is the difference between activated carbon filter and quartz sand filter? In the water quality pretreatment system,The activated carbon filter can absorb residual chlorine that cannot be removed in the previous stage filtration to prevent the later stage reverse osmosis membrane from being oxidized and degraded by it,At the same time, it also absorbs polluting substances such as small molecule organic matter leaked from the previous stage,It has obvious adsorption and removal effect on odor, colloid, pigment and heavy metal ions in water,It also has the effect of reducing COD.Can further reduce the SDI value of RO water intake,Guarantee SDI
Is it necessary to install the pre-water purifier? In general, it is best to install. this is the first layer of protection and the most basic filtration. unless the quality of municipal water can be guaranteed, it is basically impossible in China, the installation of the front water purifier has a long life and high cost performance. It can protect and extend the life of PP cotton or other first-class filter elements of the terminal water purifier. The better pre-filter water purifier will basically filter out the water quality much better. for example, the type of pre-filter with the Ryder West level can basically put most of the water impurities (such as rust, aquatic animals and plants, residue, etc.) is filtered out in the first line of defense, which is the first barrier protection for domestic water. It is also the most important one. At present, the environmental water quality pollution situation is quite not optimistic. it is recommended to install it. it is necessary for the sake of physical health.
