Reverse osmosis is a scientific application where dissolved contaminants in water are physically removed by passing it under pressure through a special membrane. The process is similar to the way your body's cells absorb water. Reverse osmosis will remove up to 98% of dissolved contaminants such as; minerals, salts, metals and organic matter that may be present in a water supply.
Pores in the reverse osmosis membrane are so small that only water molecules pass through. The comtaminants are rejected and drained away. A comparison of molecular size to the pore size of the reverse osmosis membrane is shown to the right.
