Usage Guidelines

1. 1.Dissolution:
   • Dilute powder in water (recommended ratio: 1:10 to 1:20 depending on application).
   • Stir vigorously to achieve complete dissolution (avoids clumping).
2. 2.Dosage:
   • Drinking Water: 5-20 mg/L (adjust based on turbidity and target residual Al³ levels).
   • Wastewater: 50-200 mg/L (higher for industrial effluents with high COD).
3. 3.Compatibility:
   • Works synergistically with polyacrylamide (PAM) for enhanced flocculation.

 

Advantages of Solid vs. Liquid PAC

Feature	Solid PAC	Liquid PAC
Storage	Longer shelf life (2 years)	Shorter stability (6 months)
Transportation	Lower cost (no water weight)	Higher freight costs
Dosing Flexibility	Requires dissolution step	Ready-to-use
AlO Concentration	Higher (30%±)	Lower (10%-12%)

 

Safety & Handling

• Risks:
  • Dust Inhalation: Wear N95 masks to avoid respiratory irritation.
  • Skin/Eye Contact: May cause irritation (use gloves and goggles).
• Storage:
  • Keep in dry, ventilated areas (<30°C) away from alkalis and moisture.
  • Avoid direct sunlight to prevent degradation.
• GHS Label:
  • H315: Causes skin irritation.
  • H319: Causes serious eye irritation.
