Beschreibung
Zusammenfassung:	Compositions and method for improving inhibition of calcium salt scale formation under the conditions found in chemical pulp processes in which an effective amount of selected phosphonates or phosphonate blends is admixed with the aqueous digester composition in a chemical pulping process during the digestion stage. The compositions and method are especially well suited for use in the Kraft pulping process.
