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 contaminants are rejected and discarded as wastewater. A comparison of the molecular size to pore size of the reverse osmosis membrane is shown to the right.
