What is a Reverse Osmosis Water Purification System?
Reverse Osmosis Water Treatment (RO) is a process where water (H2O) is demineralized using a semi-permeable membrane at high pressure. Pressure is applied continuously to the feedwater, forcing water molecules through the semi-permeable membrane. Water that passes through the membrane leaves the unit as product water; most of the dissolved impurities remain behind and are discharged in a waste stream. Typically, it takes several gallons of feedwater to make 1 gallon of Reverse Osmosis purified water. In a reverse osmosis drinking water system (often misspelled reverse asmosses), the idea is to use the membrane to act like an extremely fine filter to create drinkable water from salt water and otherwise contaminated water. The contaminated (or salt) water is put on one side of the membrane and pressure is applied to reverse the osmotic process.
