0887H C-1530 TITLE OF THE INVENTION MONOFLUOROPHOSPHATE FOR CALCIUM CARBONATE SCALE CONTROL AND IRON AND MANGANESE STABILIZATION ABSTRACT OF THE DISCLOSURE Monofluorophosphate salts, especially sodium monofluorophosphate (Na2P03F), when added to various industrial water systems in concentrations between 0.1 mg/L and 50 mg/L, significantly reduce the amount of calcium carbonate scale which is formed on heat exchange and other metallic surfaces of such systems. Monofluorophosphate salts, especially sodium monofluorophosphate, when added to various water systems in concentrations between 0.1 mg/L and 50 mg/L also stabilizes soluble manganese ion and its reaction products, i.e., primarily MnO2, in desirable forms and reduced particle sizes. Monofluorophosphate salts, especially sodium monofluorophosphate, when added to various water system in concentration between 1 mg/L and 500 mg/L also stabilizes soluble iron ion and its reaction products, i.e., primarily Fe203.
