Reverse Osmosis
A water treatment process that removes undesirable materials from water by using pressure to force water molecules through a semipermeable membrane. The process is called "reverse" osmosis because the pressure forces the water to flow in the reverse direction (from the concentrated solution to the dilute solution) to the flow direction in natural osmosis (from the dilute solution to the concentrated). RO removes ionized salts, colloids, and organic molecules down to a molecular weight of 100. May also be called hyperfiltration.
