What is Reverse Osmosis?
Reverse Osmosis membranes have a pore size around 0.0001 microns.
Reverse Osmosis (RO) is a membrane separation process in which water is forced through a semi-permeable membrane. Reverse osmosis was developed in the 1950s as a method of desalinating sea water. RO is highly effective in removing many impurities from water, including total dissolved solids (TDS), turbidity, asbestos, radium, lead and other toxic heavy metals. In addition RO reduces microbes and virtually all dissolved substances, as well as many organic chemicals.
Today, Reverse Osmosis is used in numerous applications that require ultra-refined water as well as to provide water in homes and offices for drinking. RO water is considered to be the most convenient and thorough method of membrane filtration.
How it Works
Osmosis is the process by which water molecules pass through a semi-permeable membrane, flowing from the side of low solute concentration to the side of high solute concentration. By applying an external pressure to the side of higher concentration this flow is reversed and Reverse Osmosis is achieved.
The membrane is the workhorse of the RO system. It is responsible for rejecting up to 98 percent of the total dissolved solids in water. Reverse osmosis is only one stage of a typical RO system. Sediment and carbon pre or post filtration are normally included with an RO system to help address additional contaminants. The effectiveness of an RO system depends on the initial levels of substances that cause water supplies to be unhealthy or unappealing (foul tastes, smells or colors). RO also reduces many additional contaminants, which if left untreated can add to adverse health effects or decreased desirability.
What type of contaminants will reverse osmosis remove?
|Contaminant||Normal Rejection %||Contaminant||Normal Rejection %|
|Copper||96-98||Ca, Mg (Hard.)||93-97|
