Reverse Osmosis water is achieved through a process that is essentially the reverse of Osmosis; whereby solvent moves from a region of low solute concentration, through a membrane, to one of high solute concentration, in an attempt to obtain equilibrium.

In Reverse Osmosis, pressure is applied to pre-conditioned mains supply water (the solution) forcing it through a module containing a spirally wrapped semi-permeable membrane that rejects the impurities (the solute), while allowing the purified water (the solvent) to pass through it. These semi-permeable membranes are designed to remove a high proportion of impurities, including up to 98% of inorganic ions, and virtually all colloids, micro-organisms, endotoxins and macromolecules. The impurities are removed from the system in a residual concentrate stream that is run to drain. The technology is extremely efficient, with nearly 70% of the feed-water passing through the membrane as purified Reverse Osmosis water.
