Difference Between drinking water and sewage treatment of NACLO
Sewage Treatment: Sodium chlorite is a highly efficient oxidant. Alkaline sodium chlorite solution is stable to light. It can react with chlorine gas in an acidic environment to release chlorine dioxide. Chlorine dioxide is a strong oxidant and is also a good water treatment and disinfection As a fourth-generation disinfectant, chlorine dioxide is very effective in industrial water treatment, and its sterilization and disinfection ability is about three times that of chlorine.
Drinking Water: The optimal concentration of chlorine dioxide prepared from sodium chlorite in drinking water purification is between 0.1 and 5.0 mg/l. Compared with chlorine, it also has better treatment functions (reducing trihalomethanes in treated water, controlling smell, etc.), no residual chlorine odor. It can also dephenolize and purify water contaminated by phenol or phenolic compounds, and remove phenol and phenolic compounds.
