An antiscalant is a chemical or substance that is used to prevent or reduce the formation of scale in industrial processes or systems. Scale refers to the deposition of mineral salts, such as calcium carbonate or calcium sulfate, that can build up and cause problems in equipment or piping systems, particularly in areas with hard water or high mineral content. Antiscalants work by inhibiting the precipitation and crystallization of these mineral salts, thus preventing their accumulation and the associated issues such as reduced efficiency, clogging, and corrosion. Antiscalants are commonly used in various industries, including water treatment, oil and gas, power generation, and chemical manufacturing, to maintain the optimal performance and longevity of equipment and systems.
