Reverse Osmosis (also known as ‘RO’)
It is the process by which water molecules are forced through a 0.0001 micron semi-permeable membrane by water pressure. Long sheets of the membrane are ingeniously pressed together and rolled up around a hollow central tube in a spiral fashion. This rolled-up configuration is commonly referred to as a spiral wound membrane or module.
For the membrane to be usable, it must be in some type of container (membrane housing) so pressure can be maintained on its surface. It is this pressure that supplies the energy to force the water through the membrane, separating it from unwanted substances. Metals, organic compounds, and other contaminants are either too large or due to their chemistry are unable to pass through the reverse osmosis membrane. The substances left behind are automatically diverted to a waste drain so they don’t build up in the system. This is accomplished by using a part of the unprocessed water (feed water) to carry away the rejected substances to the drain, thus keeping the membrane clean.
When used with sediment and activated carbon pre-filters, reverse osmosis systems can effectively remove up to 99% of all contamination making water safe and potable.
Reverse Osmosis Contaminant Removal List
|E.coli bacteria||> 99.9%|
|Fecal bacteria||> 99.9%|
|Sodium Nitrate NaNO3||97-99%|
This list represents only a few of the contaminants removed or reduced by Reverse Osmosis. Results may vary depending upon water conditions, temperature, pressure.
