Reverse osmosis

Reverse osmosis (RO) is a desalination process in which a concentrated salt solution (sea water or brackish water) is being pumped through a dense membrane at high pressure. Depending on the membrane and the conditions, either potable or demineralized water can be produced. This set-up is able to handle pressures of up to 70 bar, and solutions with particles of up to 400 µm.

RO is able to separate wastewater into a main clean and reusable water fraction and a smaller but concentrated fraction containing all organic and inorganic contaminants.
