Drinking Water Grade PAC

High-Purity Coagulant for Safe & Efficient Potable Water Treatment

    Drinking Water Grade Polyaluminium Chloride (PAC) is an advanced inorganic polymer coagulant manufactured under strict pharmaceutical-grade standards. With a high Al₂O₃ content ( 29%- 30%) and ultra-low impurity profile, it meets the standards of pre-hydrolyzed structure enables faster flocculation than traditional alum, reducing sludge by 40% while ensuring zero heavy metal risks.

How to choose drinking grade PAC?

✅ Choose white PAC when:

①The terminal water quality needs to be colorless and transparent (such as baby water/high-end bottled water)

②The process includes membrane filtration (RO/UF/MF) and the inlet water iron>0.1 ppm

✅ Choose light yellow PAC when: 

①Water plants that treat surface water/reservoir water (color <30 TCU)

②Cost-sensitive projects (daily processing capacity>10,000 tons)

③Activated carbon/ozone at the back end to ensure color meets the standard

Instruction of drinking grade PAC 

1. Before use, add PAC to tap water at a concentration of 5%-10% and stir it to be fully dissolved .

2. The dosage can be determined by lab test based on the properties of the raw water and the amount of alum flowers formed.

3. Generally, it is used on the same day of preparation. It is normal to have a slight sediment.

Package of drinking grade PAC

PAC is easy to absorb moisture,so it should be stored in cool and dry place, avoid from rain and sunlight, at the temperature no higher than 40 ℃.
