A physical-chemical water treatment process in which the pressure applied by a pump forces the water through a semi permeable membrane, removing most of the dissolved salts and contaminants present, producing water with the desired salinity level (drinking water, demineralised, purified, etc).
A water treatment based on the use of capillary or ceramic membranes for the removal of suspended solids, colloids, viruses, bacteria, oil and grease.
A water treatment technology combining ion exchange resins, semi permeable membranes and the application of an electric current. The electric potential generated causes the migration of the ions, which pass through the membranes and are directed to refuse channels. The resulting salt-free water can either be demineralised, purified or highly purified, as required.
