Fig. B-2: Reverse osmosis principle
In the osmosis process, watery solutions of different concentrations
are separated by a semi-permeable membrane. In keeping with the
law of nature, the concentrations try to equalise. On the side of the
higher original concentration, the so-called "osmotic" pressure is gen-
erated. In case of reverse osmosis, this osmotic pressure is coun-
tered by a higher pressure. The consequence: the process proceeds
in the reverse direction. A particular advantage of the reverse osmo-
sis technology compared to other water treatment processes is the
fact that - apart from the removal of dissolved salts - bacteria, germs,
particles and dissolved organic substances are also reduced.
