• Antiscalants are a family of chemicals designed to inhibit the formation and precipitation of crystallized mineral salts that form scale.
• Antiscalant chemicals are used to prevent the scaling & fouling of the RO membranes.
• Scale may consist of mineral fouling such as calcium sulfate, calcium carbonate, barium sulfate, silica, calcium fluoride, and strontium sulphate
• Some common membrane foulants and Scalants include calcium carbonate, calcium sulfate, barium sulfate, strontium sulfate, calcium fluoride, iron, colloidal material, silica and other organic contaminants.
