Reverse osmosis equipment passes raw water through precision filters, granular activated carbon filters, compressed activated carbon filters, etc., and then pressurizes it through a pump, using a reverse osmosis membrane (RO membrane) with a pore size of 1/10000μm (equivalent to 1/6000 of the size of E. coli and 1/300 of the size of a virus) to convert higher concentration water into lower concentration water.

If the reverse osmosis equipment is operated properly, its life span will be greatly extended.
