Aquafeed^® 600 Antiscalant is an aqueous anionic polyelectrolyte solution for use in reverse osmosis (RO) applications. Aquafeed^® 600 Antiscalant inhibits the formation and growth of alkaline earth carbonate and sulfate scales. Aquafeed^® 600 Antiscalant also disperses suspended solids and colloids. The recommended Aquafeed^® Antiscalant for an RO system depends upon brine water chemistry, regulatory requirements, and membrane compatibility.
