The main separation object of reverse osmosis membrane is the ion range in the solution, which requires no chemicals and can effectively remove the salt in the water. The desalination rate of the system is generally more than 98%.So reverse osmosis is one of the most advanced, energy-saving and environmentally friendly desalination methods, and has become a mainstream pre-desalination process.
