Reverse Osmosis (RO) is the most effective filtration technology available. The RO process works by separating contaminants from water by forcing the water through a semi-permeable membrane. This membrane acts as a physical barrier to almost all molecules with a molecular weight greater than 200 grams/mole.
For example, the membrane may allow passage of water molecules, but blocks molecules of dissolved salt or other harmful contaminants. Unwanted molecules are blocked and discarded by the membrane while the ultra-pure water continues on for use or further treatment.
This process takes any unwanted molecules retained by the membrane and sweeps them away to your drain. This filtration process prevents the membrane’s surface from clogging, thus allowing the filter to last long.
