As we all know, different types of reverse osmosis element membrane are also used for different water quality conditions. Therefore, it is necessary to have a detailed understanding of the influent water quality, water production and other parameters before selection.
The desalination rate depends on the relative density of the thin desalination layer on the surface of membrane for ro water purifier. The denser the desalination layer, the higher the desalination ratio and the lower the water production. The key to the desalination rate of membrane for ro water purifier for different chemical substances is the structure and relative molecular mass of the chemical substances. The desalination rate of high-valent cations and complex cations exceeds 99%. The desalination rate of price cations such as potassium ions, calcium ions, and chloride ions is slightly lower, but it can also exceed 98%, and the relative molecular weight can reach 98% if it is lower than 100. , But the sludge load of organic compounds with a relative molecular mass of less than 100 is low. When selecting the type of reverse osmosis membrane, you should fully grasp the desalination rate of the selected membrane type and the required desalination rate, and select the type according to the matching of the two.
