Reverse Osmosis Equipment is the raw water through fine filter, particle activated carbon filter, compression activated carbon filter, and then through the pump pressure, the use of pore size of 1/10000μm (equivalent to the size of Escherichia coli 1/6000, virus 1/300) reverse osmosis membrane (RO membrane), Make the high concentration of water into low concentration of water, and industrial pollutants, heavy metals, bacteria, viruses and other impurities mixed into the water are all isolated, so as to meet the prescribed physical and chemical indicators and health standards for drinking, to produce clear to pure water, is the best choice for the human body to replenish high-quality water in time.
