Reverse Osmosis and Removal of Minerals in Drinking Water

June 18, 2013

OMICS Publishing Group holds the distinction of publishing peer-reviewed, world-class scientific literature at free of cost without any need to subscribe to our journals. OMICS Group provides online free access to its journals and all the articles are highly qualitative and are peer-reviewed.

Reverse Osmosis, defined as the water treatment method traditionally known for removing salt from seawater, is also used to purify the water by forcing the organic water molecules through a semi-permeable membrane or filter. The membrane layer blocks contaminants and the impurities are subsequently expelled from the environment. The result is unpolluted drinking water.

Working of Reverse Osmosis:

reverse osmosisThe Reverse Osmosis membrane has a tight pore structure (less than 0.0001 micron or 500,000 times less than the size of a human hair) that effectively eliminates up to 99% of all contaminants and impurities such as total dissolved solids, substances, malware and bacteria from the water. Anti-microbial filters used in Reverse Osmosis also help to remove unwanted odors, colors and tastes from the water. Reverse Osmosis filtering system technology is so effective that it is used by most of the leading water bottling plants.


  • Pure, the water that is clean and ice cubes
  • Removal of unnecessary odors or tastes
  • More robust tasting drinks that are mixed with reverse osmosis are to be treated with the water (coffee, tea, etc.)
  • Needs minimal maintenance
  • While not practical for cleaning public drinking water, an in-home reverse osmosis system can be affordable when compared to other home purification methods

PureLux – A Unique Approach to Reverse Osmosis:

A typical Reverse Osmosis filtration includes a sediment or chlorine eliminating pre-filter, a semi-permeable membrane, a storage container and a triggered carbon as well as post-filter. However, these home purification systems only tend to operate at 5-20% of performance, significance for every ten gallons of the water handled, only one gallon of pure water is obtained. Also, the holding container used in many of the standard units can become a breeding for bacteria and other impurities after the purification process.
