The Membrane Separation Process

The membrane separation process utilizes a high-pressure feed to forceRO-Reverseosmosis" water through a semi-permeable barrier. As the water passes through the membrane, contaminates are rejected and eventually flushed to the waste stream. The concentration of the contaminants is crucial to determine the design and operation of the membrane system. During normal operations, membranes can become fouled by colloidal material, inorganic oxides, biological matter, and scaling salts.

Fouling involves the entrapment of material in the feed water or deposits on the membrane surface. These deposits can accrue until they cause a reduction in flow, increase in feed pressure requirements, loss of salt rejection, or all three.
