REVERSE OSMOSIS

WHAT IS NATURAL OSMOSIS AND
REVERSE OSMOSIS?
Natural or direct osmosis is common in nature, found in places like the semi-
permeable membranes which are part of the vast majority of organisms (e.g. plant
roots, our own body organs, cell membranes, etc ...)
When two solutions of different concentrations of salts (TDS -Total dissolved
solids) are separated by a semi permeable membrane, it naturally produces a flow
of water from the less concentrated solution to the higher concentrated solution.
This flow continues until the concentrations on both sides of the membrane are
equal.
To overcome this tendency, and reverse the natural flow of the system, (in
order to obtain a flow of water from a higher salt concentration solution to a
lower salt concentration solution) pressure is applied to the water on the side of
the membrane with the higher concentration. Pure water is collected from the
lower pressure side of the membrane and this process is what is called reverse
osmosis. Today, reverse osmosis is one of the best methods for improving the
characteristics of water by a physical process (without using chemicals).
