What is Reverse Osmosis?
Reverse Osmosis / RO is a technology used to remove dissolved solids and impurities from water using a semi-permeable RO membrane which allows the passage of water but leaves the majority of dissolved solids and other contaminants behind. The RO membranes require water to be under high pressure (greater than osmotic pressure) to do this. The water that passes through the RO membrane is referred to as the “permeate” and the dissolved salts that are rejected by the RO membrane is referred to as the “concentrate”. A properly run RO system can remove up to 99.5% of incoming dissolved salts and impurities.
