Industrial Applications in Bangladesh
Bangladesh Market Context: Combined with PAC and Anionic PAM in a 3-stage dosing train, this decolorizing agent enables Bangladesh dyeing mills to achieve crystal-clear ETP discharge (<150 Pt-Co color units) at minimal dosage (30–100 ppm).
- 95%+ color removal from high-colority cotton reactive, indigo, acid, and disperse dye house wastewater
- Simultaneous 50%–70% COD reduction when dosed alongside Poly Aluminium Chloride (PAC)
- Pulp & paper effluent decolorization and printing ink wastewater treatment

Other ETP & Water Treatment Chemicals Sourced from China
PAC (Poly Aluminium Chloride) 28%–30% Spray-Dried
Spray-dried 30% Al2O3 Poly Aluminium Chloride (PAC) with high basicity (70%–90%) and <0.3% water insolubles for rapid coagulation of textile dyeing effluent and industrial water clarification.
PAM (Polyacrylamide — Anionic APAM & Cationic CPAM Flocculant)
Ultra-high molecular weight Anionic PAM (12–22M Da for rapid ETP clarifier floc settling) and Cationic PAM (20%–60% ionicity for screw-press and belt-press sludge dewatering).
Ferrous Sulphate Heptahydrate 98% (ETP & Industrial Grade)
Dry, free-flowing Ferrous Sulphate Heptahydrate 98% (Fe2+ ≥ 19.7%) for cost-effective physico-chemical ETP coagulation, sulfur/reactive dye precipitation, and Fenton oxidation.
