ABSTRACT:
A threshold scale inhibitor for aqueous solutions containing calcium and magnesium scale forming ions comprises a mixture of three components: a maleic acid or anhydride homopolymer, an organophosphonate and a sulfonated styrene-maleic acid copolymer. Synergism results from the use of such inhibitor. The inhibitor is useful for inhibiting scale formation with seawater distillation apparatus, reverse osmosis apparatus, electrodialysis apparatus, boilers, heat exchange systems, etc. and is employed in small amounts, such as 0.1 ppm to 200 ppm.
