  • Stabilization of aqueous systems that include scale-forming salts and inorganic particulates involves a variety of mechanisms. Inhibition is one conventional mechanism for eliminating the deleterious effect of scale-forming salts.

[0060] Another stabilization mechanism is the dispersion of precipitated salt crystals. Synthetic polymers having carboxylic acid groups function as good dispersants for precipitated salts such as calcium carbonates. In this mechanism, the crystals stay dispersed rather than dissolving in the aqueous solution.
