title: Effect of optimized three-component antiscalant mixture on calcium carbonate scale deposition.
abstract: The mixture of 1-hydroxyethane-1,1-diphosphonic acid (HEDP), and polyacrylic acid (PAA) and synthesized hydrolyzed polymaleic anhydride (HPMA) was optimized by using simplex lattice of Design-Expert software through calcium carbonate precipitation method. The optimum mass ratio of HEDP, PAA and synthesized HPMA was obtained at 10/10/80, which showed excellent performance on controlling calcium carbonate deposition. The antiscale efficiency of the optimum mixture was 84% and 95%, respectively, in the calcium carbonate precipitation test and the calcium carbonate scale deposit test. The optimum mixture could disturb the crystal growth of calcium carbonate and then affect the morphology and crystal structure of the calcium carbonate precipitates.
