Reverse Osmosis: Water Treatment Process

Reverse Osmosis (RO) is a water purification methodology that removes ions, molecules and other larger particles from drinking water using a semipermeable membrane. The process of removing salt from seawater or desalination is done by reverse osmosis.

History of Reverse osmosis:

The process of Reverse Osmosis by using semipermeable membrane was observed first in 1748 by a French clergyman and physicist Jean Antoine Nollet.

University of California at Los Angeles was the first to investigate in 1950, desalination of seawater using semipermeable membranes. In 1950s, researchers from both University of California and University of Florida successfully produced fresh water from seawater.

Cape Coral, Florida in 1977 became the first municipality in the US to use the reverse osmosis process on a large scale.

By the end of 2001, around 15,200 desalination plants came into operation worldwide, out of which 20% of them were in the U.S.
