The process of Reverse Osmosis (RO) uses a semi-permeable membrane to remove minerals and dissolved solids from water.

The product water transfers through the membrane while dissolved solids, particulates, and organic matters are flushed to drain as a concentrate or wastewater. 

Not only does the process remove organic molecules and viruses, it also removes most minerals present in the water as well as monovalent ions, resulting in a desalination of water. 

As a result, once water passes through a reverse osmosis filter, it is essentially pure water. Typically, a single pass reverse osmosis system typically removes 97% of the total dissolved solids and 95% of naturally occurring organics with water recovery usually ranging from 65 to 80%.
