Polyaluminum Chloride is an inorganic polymer aluminum salt commonly referred to as PAC, polyaluminium chloride, or basic aluminum chloride, all representing the same industrial coagulant material. Identified by CAS 1327‑41‑9, it consists of polymerized aluminum hydroxy complexes that promote charge neutralization and particle aggregation during treatment processes. In industrial operation, it is primarily used in water treatment coagulation, where it facilitates suspended solids removal and clarification in municipal and industrial water treatment systems.
For industrial supply, this product is offered with competitive factory pricing, customized specifications, and full documentation including MSDS, TDS, COA, supporting bulk supply for continuous treatment operations.

Industrial-grade polyaluminum chloride is an inorganic polymer coagulant with large molecular weight and high charge produced by the bridging of hydroxide ions and the polymerization of polyvalent anions.
Industrial grade polyaluminum chloride is mainly used for the purification of drinking water, production water, various wastewater and sewage purification treatment and special water quality treatment. It has the effects of deodorizing, sterilizing, color removal, and corrosion removal. It has significant effects in treating industrial wastewater containing iron, chromium, manganese, zinc, phenol, sulfur, fluorine, etc.
FAQ - Technical & Supply Chain
-
Q:
Does CAS 1327-41-9 specifically identify Polyaluminum Chloride?
A: Yes, CAS 1327-41-9 is the standard registry number for Polyaluminum Chloride (PAC), covering various grades of this inorganic polymer coagulant. -
Q:
How does Polyaluminum Chloride function in water treatment coagulation processes?
A: Polyaluminum Chloride provides polymerized aluminum species that neutralize surface charges on suspended particles, allowing them to aggregate into larger flocs for efficient separation during clarification.
