Abstract
The present invention is directed a multifunctional polymer capable of inhibiting both calcium carbonate and calcium phosphate scale. The multifunctional polymer contains at least one monomer unit from each of four groups: dicarboxylic acids, mono-carboxylic acids, nonionic monomers, and sulfonated or sulfated monomers. The polymer also inhibits many other alkaline earth scales, such as calcium sulfate scale and provides stabilization of minerals such as iron, zinc and manganese. The polymer is especially effective in highly stressed systems that contain high electrolyte concentrations and have a high number of cycles of concentration.
