Abstract

A method of treating hardness present in boiler waters which are in contact with heat transfer surfaces to prevent and remove scale caused by such hardness which comprises treating such waters with a water soluble anionic vinyl polymer containing at least 30% by weight of carboxylate functionality with said polymer having a molecular weight within the range of 500 50,000 and with the amount of such polymer being within the range of 1 - 30 ppm per ppm hardness present in such waters. In a preferred embodiment, the boiler waters are simultaneously treated with the water-soluble anionic vinyl polymers containing carboxylate functionality and another watersoluble anionic vinyl polymer which has dispersing properties.
