Why Does Solid PAC Have Different Grades?

Poly Aluminum Chloride (PAC) is a highly effective coagulant used in water treatment for industrial wastewater, drinking water, and food processing.

Due to varying water quality requirements across industries, PAC is classified into industrial-grade, drinking-water-grade, and food-grade to ensure safety and efficiency.

Industrial-Grade PAC

Applications: 

Industrial wastewater treatment, municipal sewage, paper mills, textile factories, etc.

Features:

-Higher heavy metal content (meets industrial standards but unsafe for humans).

-High treatment efficiency and low cost.

-Not suitable for drinking water or food processing.

Drinking-Water-Grade PAC

Applications: 

Tap water purification, drinking water treatment, swimming pool cleaning, etc.

Features:

-Extremely low heavy metal content (complies with GB 15892-2020 standards).

-No harmful residues, ensuring safe drinking water.

-Excellent flocculation effect for clear water.

Food-Grade PAC

Applications: 

Food processing water, beverage production, pharmaceutical water, etc.

Features:

-Highest purity, almost free from heavy metals and impurities (meets GB 25571-2010 food safety standards).

-Suitable for high-hygiene water treatment needs.

-Higher cost but offers the best safety.

How to Choose the Right PAC Grade?

-Industrial wastewater → Industrial-grade PAC (cost-effective)

-Drinking water treatment → Drinking-water-grade PAC (safe & compliant)

-Food/pharmaceutical water → Food-grade PAC (highest standard)

Choosing the correct PAC grade improves water treatment efficiency and avoids safety risks.
