Does CAS 1327-41-9 define one fixed Polyaluminum Chloride grade?

No. Polyaluminum Chloride is a family of polymerized aluminum coagulants. Products under CAS 1327-41-9 can differ in liquid or powder form, Al2O3 concentration, basicity, sulfate content and impurity limits, so the grade must be specified separately.

What is Polyaluminum Chloride used for?

It is used as an inorganic polymer coagulant in drinking-water, process-water and wastewater treatment, and for color, turbidity, iron, manganese and organic removal. The selected grade and dose depend on the raw water, pH, solids loading and applicable water standard.

Which PAC values should be stated when requesting a quotation?

State liquid or powder form, Al2O3 content, basicity, pH, water-insoluble matter, iron and required heavy-metal limits, together with the applicable standard and test basis. For liquid PAC, also confirm specific gravity and delivered concentration.

Can wastewater-grade PAC be used automatically for drinking-water treatment?

No. Potable-water use requires compliance with the applicable local drinking-water standard and tighter impurity controls. Confirm regulatory acceptance first, then use jar testing on the actual raw water to select grade and operating dose.

What should an RFQ include for Polyaluminum Chloride?

State CAS 1327-41-9, liquid or powder form, Al2O3 content, basicity, impurities and applicable standard, quantity, packaging and destination. Confirm drum or bulk handling, shelf life and storage conditions before ordering.

Polyaluminum Chloride CAS 1327-41-9

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. Polyferric Sulfate (PFS) is an iron-based coagulant alternative for treatment-program comparison.
For industrial supply, this product is offered with 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 to purify drinking water, process water and various kinds of wastewater and sewage, and for special water-quality treatment. It provides deodorizing, sterilizing, decolorizing and impurity-removal effects, and is highly effective for industrial wastewater containing iron, chromium, manganese, zinc, phenols, sulfides and fluorides.
