Our wide selection of scale inhibition chemistry can be tailored for any treatment scenario. Learn more at www.wateradditives.com
The highest performing antiscalants on the marketBWA’s scale control products are designed for both exceptional technical performance and environmental responsibility. The maleic, phosphinocarboxylic and phosphonocarboxylic acid technology on which BWA products are based has led to additives which out-perform polyacrylates and acrylic copolymers. Our POCA polymers offer a unique performance profile that cannot be matched by homopolymers or copolymers. BWA’s excellent inhibitor performance is reliable and efficient, which provides better heat transfer and lower energy cost.
