Diminishing use of heavy metal corrosion inhibitors and increased reuse of water has demanded the implementation of alternate treatment techniques for cooling water. This paper discusses the development and use of unique polymer technology capable of effectively controlling calcium phosphate precipitation. Patented chemistry utilizes functional groups that provide polymer stability in stressed cooling water systems while exhibiting calcium phosphate inhibition at low treatment levels. Polymer function is not affected by aqueous iron (II) and demonstrates significant performance as an iron inhibitor and iron oxide dispersant.
