Product Introduction:
Sodium Sulfite is a highly soluble inorganic salt, widely used as a stabilizer for synthetic fibers, textile bleaching agent, photographic developer, deoxidizer for dyeing and bleaching, reducing agent for flavors and dyes, and lignin remover in paper making. In water treatment, it serves as an effective dechlorinating and deoxygenating agent for boiler water, oilfield injection water, municipal, and industrial water systems. It is also used in wastewater treatment to reduce toxic hexavalent chromium to less toxic trivalent chromium and to precipitate and separate metals like silver and mercury.
