application | calcium sulfite can remove residual chlorine in water, including chemical residual chlorine NH2CL,NHCL2 and NCL3 and free residual chlorine CLO-,HOCL,CL2, etc. Compared with traditional activated carbon, the chlorine removal effect is more efficient, safe, high temperature resistant, and no bacteria breeding, it is widely used in various water to remove residual chlorine in Southeast Asian countries and regions such as Japan, South Korea, Malaysia, and Taiwan. |
Use | Used as analytical reagent, also used in textile, papermaking and sugar industries, etc. Used as analytical reagent, also used in making calcium and plastic materials, and also used as cellulose products Bleaching dechlorination agent, food preservative, fermentation fungicide, etc. |
