Dosing Guidelines

Typical dosing: 10-150 mg/L as Al₂O₃. Lower doses required compared to conventional alum. Optimal pH: 5.0-9.0.

How It Works

PAC works through a combination of charge neutralization and sweep flocculation. Pre-polymerized form provides faster reaction and larger floc formation.

Usage Tips

Can be fed directly without dilution. Store above 0°C to prevent crystallization. Compatible with most treatment systems.

Frequently Asked Questions

What does 'PC 30' mean in the product designation?
PC 30 indicates Polyaluminum Chloride with approximately 30% aluminum oxide (Al₂O₃) content. This concentration provides optimal balance between handling characteristics and coagulation efficiency.
Can PAC crystallize during storage, and how can this be prevented?
PAC can crystallize at temperatures below 0°C or during extended storage. Maintain storage temperature above 5°C and use products within 6 months. Gentle warming can redissolve crystals without affecting performance.
How does PAC performance vary with water temperature?
PAC performs well across a wide temperature range (1-40°C). Cold water may require slightly higher doses and longer flocculation time, while warm water typically shows faster kinetics and better floc formation.
Is dilution required before feeding PAC?
Liquid PAC can be fed directly without dilution, which simplifies handling and reduces labor. For very precise dosing or low flow applications, 2:1 dilution may improve accuracy and reduce chemical consumption.
What equipment materials are compatible with liquid PAC?
Use PVC, CPVC, polyethylene, or FRP materials for storage and piping. Avoid aluminum, carbon steel, and galvanized components which can corrode and affect product quality. Stainless steel 316L is acceptable for pumps and valves.
