Polyether polyamino methylene phosphonates, which possess high calcium tolerance and have been found to give excellent inhibition of the formation, deposition and adherence of scale-forming salts, especially calcium carbonate, in aqueous systems involving severe conditions which include elevated pH, high dissolved solids content, and high saturation levels of calcium carbonate, are degraded by the oxidizing biocides bromine and chlorine used to control microbial growth in such aqueous systems. It has been found that organic sulfonamides provide excellent protection against such degradation when they are added to the aqueous system along with the polyether polyamino methylene phosphonate scale inhibitors.
