    As we all know, reverse osmosis membrane technology is a membrane separation and filtration technology that uses the pressure gauge difference as the power, and reverse osmosis element membrane can effectively remove impurities such as inorganic salts, heavy metal ions, organic matter, colloids, bacteria, and viruses in the raw water. Reverse osmosis equipment not only needs reverse osmosis element membrane, its stainless steel membrane shell is also one of the main components. Stainless steel membrane shell is a pressure vessel with stainless steel head, which is manufactured by spiral winding production process, with excellent characteristics, high toughness and light weight. application.
