反渗透设备是膜法水处理设备的一种，反渗透技术是当前制备纯水及高纯水是应用最广的一种设备。在膜设备中，反渗透膜可去除离子级杂质，使出水达到纯水及高纯水的标准。反渗透膜的膜孔径非常小，因此能够有效的去除水中的溶解盐类、胶类、微生物、有机物等(去除率高达97%-98%)。系统具有水质好、耗能低、无污染、工艺简单、操作简单等优点。

Reverse osmosis equipment is a membrane water treatment equipment, reverse osmosis technology is the current preparation of pure water and high purity water is the most widely used a device. In the membrane equipment, the reverse osmosis membrane can remove ion-grade impurities, so that the water to achieve the standard of pure water and high purity water. The membrane diameter of the reverse osmosis membrane is very small, so it can effectively remove dissolved salts, gums, microorganisms and organic matter in water (the removal rate is up to 97% -98%). The system has the advantages of good water quality, low energy consumption, no pollution, simple process, simple operation and so on.
