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.
