Reverse Osmosis, commonly referred to as RO, is a process of removing water or deionized water by pushing water through a semi-permeable reverse osmosis membrane under pressure. To understand the purpose and process of reverse osmosis, you must first understand the natural processes of infiltration. Next, Reverse Osmosis Systems Manufacturer will take you through the specifics of reverse osmosis.

Infiltration is a naturally occurring phenomenon and one of the most important processes in nature. This is a process in which a weaker saline solution tends to migrate into a strong salt solution. An example of infiltration is that the roots of plants absorb water from the soil, and our kidneys absorb water from the blood.

Lower concentration solutions have a natural tendency to migrate to solutions with higher concentrations. For example, if you have a container filled with water with a low salt concentration and another container filled with water with a high salt concentration and separate them with a semi-permeable membrane, the water with a lower salt concentration will begin to migrate towards Water container with a higher salt concentration.

A semipermeable membrane is a membrane that allows some atoms or molecules to pass but does not allow other atoms or molecules to pass through. A simple example is a screen door. It allows air molecules to pass through anything other than pests or holes larger than the holes on the screen door. Another example is the Gore-tex apparel fabric, which contains an extremely thin plastic film in which billions of small holes have been cut. The pores are large enough to allow water vapor to pass through but small enough to prevent liquid water from passing through.

Reverse osmosis is a reversal of the infiltration process. Although osmosis occurs naturally without energy, in order to reverse the infiltration process, you need to apply energy to the salt solution. Reverse osmosis membranes are semipermeable membranes that allow water molecules to pass through rather than mostly dissolved salts, organics, bacteria, and pyrogens. However, you need to “push” water through the reverse osmosis membrane by applying a pressure greater than the natural osmotic pressure to desalinate (demineralize or deionize) the water during the process, allowing pure water to pass through while blocking most of the contaminants.
