Industrial Applications in Bangladesh
Bangladesh Market Context: The most economical primary coagulant and reducing agent used in high-volume Bangladesh dyeing and denim washing ETPs (dosed with lime/caustic at pH 8.5–9.5 or with H2O2 in Fenton towers).
- Primary coagulation and reductive decolorization of reactive, sulfur, and vat dye effluent in textile ETPs
- Catalyst in Fenton reagent (Fe2+ + H2O2) advanced oxidation for refractory COD destruction
- Phosphate removal, cement chromate reduction, and agricultural micronutrient fertilizer
