Reverse osmosis membrane is a kind of membrane with selective permeability performance, which can effectively separate water molecules and dissolved solids, organic matter, inorganic matter and other impurities. The working principle of reverse osmosis membrane is to make use of the selective permeability of semi-permeable membrane to separate seawater or contaminated water from fresh water under high pressure, so that the fresh water passes through the semi-permeable membrane, while the salt, organic matter, microorganisms and other impurities in seawater remain on the other side of the membrane.


The advantage of reverse osmosis membranes is that they can efficiently remove salts and impurities from seawater to produce high-quality fresh water. Compared with traditional desalination methods, reverse osmosis membrane technology has the advantages of low energy consumption, low cost and easy operation. In addition, reverse osmosis membrane can also be used in the field of wastewater treatment, water softening, drug separation, etc. JX-SWRO has the characteristics of high desalination rate and high water yield, which is crucial.


The development of reverse osmosis membrane can be traced back to the 1950s, when American scientists first discovered the phenomenon of reverse osmosis. With the continuous development of materials science and membrane technology, the performance of reverse osmosis membrane has been greatly improved, and the scope of application is also expanding. At present, reverse osmosis membrane has become one of the mainstream technologies in the field of seawater desalination.


However, reverse osmosis membranes also have some problems and challenges. For example, the life and stability of reverse osmosis membranes are still important factors restricting their application, and problems such as membrane contamination and membrane failure need to be further solved. But JX-purification's seitan solves this problem, our membrane warranty of three years is no problem, and the membrane sheet has NSF certification. jx-swro is benchmarked with LG.


Overall, reverse osmosis membrane is an important seawater desalination technology with broad application prospects. With the continuous development of technology and cost reduction, reverse osmosis membrane technology will play an increasingly important role in the field of seawater desalination.
