Reverse Osmosis is a process for treating water by demineralizing them as they flow under pressure through a semi-permeable membrane. Reverse osmosis is the process or the technology which is used to remove ions, mineral chemicals, and other impurities from drinking water. In this process, greater pressure is applied, forcing the water to travel through the semipermeable membrane in opposition to natural osmosis. Standard water filters will physically screen any dirt and sedimentary particles down to a size of about one micron but cannot remove dissolved chemicals. Reverse osmosis filters and removes dissolved chemicals, salts and minerals. RO filtration ensures that lead, chlorine, fluoride, and other impurities are removed from your drinking water. Reverse Osmosis water filtration is unrivaled when it comes to removing impurities from water in an efficient, cost-effective method.
