Title: Using Tagged Polymers as Phosphonate Replacements in Water Treatment Applications
Water treaters often use multicomponent formulations, which include polymers and phosphonates to prevent calcium carbonate and calcium phosphate scale formation and provide dispersancy in their systems. With phosphonates in short supply, polymers are being more heavily relied upon to provide scale control. Water treaters can benefit from the ability to detect active polymer to ensure their systems are well protected when formulation changes are necessary. Using fluorescent-tagged polymers, water treaters can determine the amount of available polymer and ensure that there is enough polymer to control scale, even when system upsets or disruptions result in stressed conditions. Unlike conventional polymers, tagged polymers provide constant feedback, whether the polymer is working or not, thus taking the guesswork out of the equation. This paper will provide information on phosphonate replacement including field trial data for tagged polymers in both alkaline pH systems and neutral pH/stabilized phosphate systems.
