Effect of dosage of coagulant on the color removal efficiency. [Display omitted] ► Color removal was enhanced by AS–SA, which performed better than AS. ► AS plus SA exhibited an obvious improvement on floc size and floc growth rate. ► At low AS dose, flocs formed by AS–SA had a better restoration ab...
