An antiscalant is dosed continuously into feed water to keep dissolved minerals from crystallizing into hard scale on membranes, pipework, and heat-transfer surfaces. Reverse-osmosis desalination plants, industrial water-treatment systems, cooling towers, and boilers all depend on this function: without it, scale gradually blocks membranes and fouls surfaces, cutting throughput and raising energy use until the equipment is cleaned or replaced. The right antiscalant and dose depend on the feed water's own mineral content, so operators typically confirm both from a water analysis before dosing begins.
