Reverse osmosis water purifier is a kind of equipment that filters water through reverse osmosis membrane, which is mainly used to remove pollutants and impurities in water and provide clean and safe drinking water.

The working principle of reverse osmosis water purifier is to force water through the reverse osmosis membrane through high pressure, so that water molecules pass through the membrane hole, and pollutants and impurities are trapped outside the membrane, so as to achieve water filtration and purification.

Specifically, the filtration process of the reverse osmosis water purifier is as follows: 1. Pretreatment: First, the raw water is initially filtered through the pre-filter to remove large particle impurities and suspended matter in the water. 2. High pressure pumping water: The pre-treated water is pressurized through the high pressure pump to push the water through the reverse osmosis membrane. 3. Reverse osmosis membrane filtration: Water flows through the reverse osmosis membrane after being pressurized by a high pressure pump, and only water molecules smaller than the diameter of the membrane hole can pass through the membrane hole, while most of the pollutants are trapped outside the membrane. 4. Discharge wastewater: After filtration through reverse osmosis membrane, part of the water flow becomes clean water, and the other part becomes waste water, which contains a large number of concentrated pollutants and needs to be discharged and treated. 5. Collect clean water: The water is stably stored in the tank after filtration, and can be used for drinking or other purposes.

The filtration process of reverse osmosis water purifier mainly realizes the purification and filtration of water through the reverse osmosis membrane. The filtration accuracy of reverse osmosis membrane is very high, which can effectively remove microorganisms, heavy metals, organic matter, colloids and other pollutants in water to ensure the safety and health of water quality.

In general, the reverse osmosis water purifier is an efficient water purification equipment that filters water through the reverse osmosis membrane to achieve the removal of pollutants and impurities in the water and provide clean and safe drinking water.
