The concepts of water conservation and the stringent wastewater discharge regulations have dictated today's cooling water systems running at higher and higher cycles of concentration. Under such severe water conditions, scale/deposit control has become quite complicated involving a variety of scaling species. Categorically speaking, maleate
based polymers/copolymers, along with phosphonates, are used to control calcium carbonate while sulfonate based polymers/copolymers are used to control calcium phosphate, iron, and other particulate. Presented here is a new single polymer designed to deliver comprehensive antiscaling performances collectively provided by these two classes of polymers.
