ETP Treatment Steps & Best Chemicals Used

1. pH Correction

pH control is the first and most important step in any ETP.

• Chemicals Used: Caustic Soda (NaOH), Lime, Soda Ash, Hydrochloric Acid (HCl)
• Purpose: Neutralization & preparation for coagulation
• Ideal pH: 6.5 – 7.5

2. Coagulation

To destabilize suspended particles, oil, grease, colour molecules.

• Best Coagulants:
  • Alum
  • Ferric Chloride
  • PAC (Poly Aluminium Chloride)
  • Ferrous Sulphate
• Dosage Method: 50 – 500 ppm (based on jar test)
• Action: Breaks colloidal bonds & settles sludge bottom.

3. Flocculation

To form big flocs after coagulation for fast settling.

• Flocculants:
  • Anionic Polyelectrolyte
  • Cationic Polyelectrolyte
  • Non-ionic Polymer
• Dosage: 0.1 – 1.0 ppm (Highly concentrated — cost saving)
• Purpose: Settling efficiency increase 5×

4. Colour Removal (Textile / Dyeing / Chemical Units)

• Decolourants:
  • Polyamine
  • Decolourant DCD
  • Anionic colour remover
• Action: Removes 80–95% colour

5. COD/BOD Reduction

• Chemicals Used:
  • Hydrogen Peroxide + Catalyst
  • Fenton’s Reagent
  • Copper-based oxidizers
  • Biological enzyme boosters
• Result: COD reduction from 2500 → 350 mg/L

6. Sludge Management

• Sludge thickener chemical
• Polymer for dry cake
• Drying bed improvement
