reverse osmosis system，also known as the reverse osmosis pure water equipment, is composed of a single group of RO membranes and sand tanks. The carbon canister, after fine filtration, directly enters the RO host, and the separated pure water is supplied to the system directly used by the production water point. When the primary reverse osmosis pure water equipment works, the raw water pump pressurizes the raw water through the quartz sand filter, activated carbon filter, precision filter, etc., and then pressurizes the raw water through the high-pressure pump with an aperture of 1/10000 μ M (equivalent to 1/6000 of the size of E. coli and 1/300 of the virus) reverse osmosis membrane (RO membrane),
