FFM Inc\'s High-Rejection membrane element is the most widely used reverse osmosis membrane for desalination of brackish water, which is specially used for desalination and desalination of brackish water. It has the characteristics of low operating pressure, good desalting performance, not easy to be polluted and blocked, stable technical performance, good water quality, high water yield, good anti pollution and so on. It shows high comprehensive superior performance of the system in the use process. Membrane elements are suitable for desalination of well water and surface water sources with salt content less than 5000ppm, pre desalination before drinking water purification and ion exchange system. They are mainly used for industrial pure water of various scales, boiler make-up water of power plants and other industrial water, and can also be used in brackish water application fields such as high concentration saline wastewater and beverage water manufacturing.
