    摘要: Method for inhibiting scale deposits in an aqueous system. The method may include at least one of adding and forming anti-scalant in the aqueous system such that an amount of anti-scalant in the aqueous system is up to about 1000 ppm, wherein the anti-scalant comprises at least one of polyvalent metal silicate and polyvalent metal carbonate, wherein the aqueous system has a pH of at least about 9, and wherein a mean particle size of the anti-scalant is less than about 3 microns. The method may also include at least one of adding and forming anti-scalant in the aqueous system such that an amount of anti-scalant in the aqueous system is up to about 1000 ppm, wherein the anti-scalant comprises at least one of polyvalent metal silicate and polyvalent metal carbonate, and wherein the aqueous system has a pH of at least about 9; and adding dispersant to the aqueous system. The method may involve forming anti-scalant in the aqueous system such that an amount of anti-scalant in the aqueous system is up to about 1000 ppm, wherein the anti-scalant comprises at least one of polyvalent metal silicate and polyvalent metal carbonate, and wherein a mean particle size of the anti-scalant is less than about 3 microns. The method may further include at least one of adding and forming anti-scalant in the aqueous system, wherein the anti-scalant comprises at least one of polyvalent metal silicate and polyvalent metal carbonate; and adding at least one protein to the aqueous system. Compositions therefor.
