Reverse osmosis is the finest level of filtration available.
The RO membrane acts as a barrier to all dissolved salts and
inorganic molecules, as well as organic molecules with a molecular
weight greater than approximately 100. Water molecules, on the
other hand, pass freely through the membrane creating a purified
product stream. Rejection of dissolved salts is typically 95% to
greater than 98%. The applications for RO are numerous and varied,
and include desalination of sea water or brackish water for
drinking purposes, wastewater recovery, food and beverage
processing, biomedical separations, purification of home drinking
water and industrial process water.
