Problems solved by technology

[0002] Reverse osmosis is an efficient water purification method, which has the advantages of high efficiency, low cost, no phase change, easy integration, modularization and automation, etc. It is widely used in the preparation of high-purity water in the electronics industry, medical water preparation, seawater desalination, In many fields such as water desalination and sewage recycling, with the shortage of global fresh water resources and the increasingly serious water pollution, reverse osmosis technology is playing an increasingly important role in purification. In the prior art, reverse osmosis membranes lack operating pressure Low, large water production, raw materials environmental protection, high desalination rate advantages, the present invention proposes an ultra-low pressure reverse osmosis filter and its preparation method
