Industrial Water Treatment Antiscalants

Industrial Water Treatment Antiscalants
The highest performing antiscalants on the market
BWA’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.
Our wide selection of scale inhibition chemistry can be tailored for any treatment scenario.
