Alumina Refining Solutions and Processing Aids Market

An alumina refinery needed to extend the life of one of its critical red mud washers. The washer, used to recover high-cost caustic soda, required a solution that reduced the formation and growth rate of scale. By introducing SCALE-GUARD™, Nalco Water was able to help extend the life of the washer from 180 to 200 days and reduce the thickness of the scale by 50%, making it easier to clean
