Understanding Polyaluminium Chloride (PAC) Specifications, Grades and Supplier Selection

Choosing the right Polyaluminium Chloride (PAC) (聚合氯化铝) comes down to reading the specification sheet correctly. This guide explains the numbers that matter and how to select a supplier you can trust.

Key Specifications of Polyaluminium Chloride (PAC)

As an PAC coagulant, the product is defined by a small set of parameters:

• Molecular formula: Al2Cln(OH)6-n
• CAS No.: 1327-41-9
• Appearance: Golden yellow, earthy yellow, brown powder
• Packaging: 25kg bag (inner plastic, outer PP woven)
• Standard: GB/T 22627-2022

Grade and Quality Considerations

Not all industrial water plant treatment chemicals are equal. For Polyaluminium Chloride (PAC), confirm active content, moisture and impurity limits against the cited standard. A reputable PAC coagulant supplier provides a Certificate of Analysis (COA) per batch and supports third-party testing.

Selection Checklist

1. Match the application: Purification of drinking water, domestic wastewater, various chemical wastewater, industrial production.
2. Confirm packaging matches your handling (drum vs. bag, 25kg bag (inner plastic, outer PP woven)).
3. Verify the standard (GB/T 22627-2022) and request documentation.
4. Check lead time and container-load options for export.

Storage and Handling

Store Polyaluminium Chloride (PAC) in a dry, ventilated area away from incompatible substances. Follow the MSDS for PPE and spill response. Many buyers combine this product with Calcium Chloride in a single sourcing plan to reduce freight and admin cost.
