Application
Calcium sulfite can remove residual chlorine from water, including combined residual chlorine (NH2Cl, NHCl2, and NCl3) and free residual chlorine (ClO-, HOCl, and Cl2). Compared with traditional activated carbon, it has a more efficient chlorine removal effect, is safer, more resistant to high temperatures, and does not breed bacteria. It is widely used in various water treatments for residual chlorine removal in Southeast Asian countries and regions such as Japan, South Korea, Malaysia, and Taiwan.
