    Reverse Osmosis (RO) Chemicals

    Reverse osmosis (RO) is an efficient method for purifying water, but to maintain operational efficiency, it is crucial to keep the plant, especially the membranes, clean. Failure to do so results in rapid fouling of the membranes, leading to decreased output and the costly necessity of replacement.

    To address these challenges, various products have been developed specifically for the membrane and reverse osmosis markets. The first line of defence against fouling involves the correct application of reverse osmosis anti-foulants and anti-scalants. These products work to reduce fouling in the initial stages. Additionally, membrane cleaning products are essential for removing fouling from the membranes. The choice of cleaning products should be based on the type of fouling that occurs. In cases where biofilms form on the membranes, biocidal products become necessary components of the membrane treatment regime.

    By employing a combination of anti-foulants, anti-scalants, membrane cleaning products, and biocidal treatments, operators can maintain the efficiency of reverse osmosis plants, ensuring consistent water quality and prolonging the lifespan of membranes.
