A reverse osmosis water purifier is a common type of water treatment equipment used to remove impurities and contaminants from water to produce highly pure water. Reverse osmosis technology filters dissolved solids, organic matter, bacteria and viruses from water through a semi-permeable membrane. Reverse osmosis-treated water is usually considered safe and pure enough to drink directly.
Reverse osmosis water purifiers work by passing water through a series of filters and semi-permeable membranes to remove impurities and contaminants from the water. The process involves physical filtration and osmosis, where the semi-permeable membrane allows only water molecules to pass through while preventing the passage of other solutes.
