Reverse Osmosis is best known for its use as a water filter method for turning sea water into drinkable water. However, it is also an extremely effective way to treat water for organic and inorganic particles. It can reduce the number of contaminates that are commonly found in water.

The key to the reverse osmosis water filtering method is the semi-permeable membrane that is only permeable to water. The reverse osmosis membranes will repel contaminates based on their atomic weight or molecule size. Organic matter, such as bacteria and some viruses, and inorganic matter, such as mineral salts and metals, can separated from the water supply. The pressure of the water feed forces unprocessed, possibly contaminated, water through the membranes, and as a result, only clean and filtered water passes through the membrane. Impure particles are trapped, and flushed away. (The temperature of the feed water can greatly affect the rate of water filtering production, the lower the water temperature, the lower the rate of production. Accordingly, the higher the water feed pressure, the better quality of filtered water.)

At Online Water Parts, we carry industrial reverse osmosis water filters & water filter parts. RO membrane products include membranes manufactured by Osmonics or Hydranautics, and membrane cleaners from Avista. Our selection includes 2" to 8" membranes. Operating pressures range from 30-225, depending on manufacturer and make. Our largest 8" RO membrane has a 10K GPD flowrate. We have access to all makes and manufacturers of membranes.
