Polymerized Aluminum Chloride (PAC) Usage Guidelines

Polymerized Aluminum Chloride (PAC) Usage Guidelines
PAC Use Methodology:
1. Prior to use, conduct a small test with water sample and PAC to determine the optimal dose for your specific water quality.
2. Always prepare fresh PAC solution as needed. Install a dissolution device and control unit (made of corrosion-resistant materials).
3. Mix 5% solid product into clean water and stir for approximately 10-30 minutes until the medication is fully dissolved.
4. For water turbidity levels between 100-500mg/L, administer 10-50g of PAC per liter or 10-50kg per ton of water. Start with a low dose and adjust based on water characteristics.
5. Ensure that PAC is exclusively prepared in pure water without pollutants or oil wastewaters.
6. Monitor and adjust the dosage accordingly considering initial testing results, site water volume and quality variations.
7. During operation, check and adjust if there are insufficient feces, high turbidity, or excessive dosage.
