An antiscalant is a chemical or pre-treatment chemical that prevents the formation of scale, or crystallized mineral salts, commonly used in water purification systems, pipelines and cooling tower applications. Antiscalants are also known as scale inhibitor agents. Scale formation occurs when the concentration of dissolved salts in water exceeds their solubility limits, leading to the precipitation of these salts onto surfaces as hard deposits. Antiscalants dissolve the substances accumulated near the membrane surface and reduce the rate of fouling.[1] They play a crucial role in preventing scale formation, thus improving the efficiency and longevity of industrial equipment and processes.
