What Type Of Membranes Are Used In Reverse Osmosis (RO)?
Reverse osmosis (RO) is a process for deionizing or purifying water by forcing it through a semi-permeable membrane at high pressure. The RO membrane is a thin layer of filtering material that removes contaminants and dissolved salts from water. A polyester support web, a micro porous polysulfone interlayer, and an ultra-thin polyamide barrier layer make up the three layers. These membranes can be used in manufacturing processes as well as in the production of potable water.

The demand for reverse osmosis
membrane was driven by the fact that a large number of countries use seawater
desalination, which relies on the RO process to remove excess salt from water
and make it ready for use.
The governments of various countries
are raising public consciousness about water-borne diseases and encouraging the
use of water filtration systems, which is driving demand for reverse osmosis
membrane filtration lines.
