With the rapid development of modern industry, more and more brine is generated. If brine is directly discharged into the nature, it will not only pollute the environment, but also affect human health. Therefore, it is necessary to recycle and utilize the brine. The current treatment of brine is to discharge the brine directly into the reaction tank for neutralization reaction, which not only causes a waste of water resources, but also the recycling effect of brine is average.

[0038] Through the above structural design, the reverse osmosis equipment can remove inorganic ions, bacteria, viruses, organic substances and colloids in the raw water, so as to obtain high-quality pure water.
