What is Reverse Osmosis ?
Reverse Osmosis is the process of forcing a solvent from a region of high solute (dissolved substance) concentration through a semi-permeable membrane to a region of low solute concentration by applying a pressure in excess of the osmotic pressure. In simpler terms, reverse osmosis is pushing a solution through a filter that traps the solute from one side and allows the obtainment of the pure solvent from the other side. A household system usually filters water through a four-stage process. 1) Raw water flows through a sediment filter to remove solid objects, typically 5 micron or larger. 2) Water then flows through a carbon block filter to remove 98% of the organics in the water. 3) The next stage removes approximately 99% of the dissolved contaminants. The reverse osmosis cartridge is responsible for this function. The remove contaminants are washed down the drain leaving only the high quality product water which is stored in the systems accumulator tank. 4) Lastly, when the product
Reverse Osmosis (RO), is a non-thermal fluid purification process. It is the finest filtration method known to man that is capable of removing particles as small as dissolved individual ions from a solution. Although RO is used to purify a host of different types of fluids, the most common application is to produce drinking water from seawater or brackish water.
