RO membrane continues to increase in demand with the growth of the water treatment sector. However, fouling and scaling are its major drawbacks. Fouling occurs in both cellulose-based and thin-film composite membranes. There are four types of fouling, namely, biological, colloidal, scaling, and organic. The saturation of salts on the surface of the membrane is core reason for scaling in the desalination plants and the fouling results in reduced flux and life span of the membrane. Fouling can be controlled to some extent by using disinfectant, anti-scaling, and other pre-treatment, which add to the cost of operation. The fouling persists and remains a key area for improvement in the quality of the membrane, which has hampered the RO membrane market growth.
