The membrane separation process utilizes a high-pressure feed to force water through a semi-permeable barrier. As the water passes through the membrane, contaminants 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 that stay behind. 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 the feed pressure requirements, loss of salt rejection, or all three. RO chemicals are needed to counteract the effects of contaminants fouling the membranes within the system.
