Is Aluminium Sulfate CAS 10043-01-3 the same material as alum?

Not always. “Alum” is used broadly and may refer to aluminium sulfate or to an aluminium–potassium double salt. Identify the offered material by its product name, CAS number and stated commercial form or grade.

Aluminium Sulfate CAS 10043-01-3

Aluminium Sulfate CAS 10043-01-3, also known as aluminum sulfate or dialuminium trisulfate, is an inorganic coagulant used in industrial and municipal water clarification, wastewater treatment and paper manufacturing. Polyaluminum Chloride (PAC) is a related coagulant option where the treatment specification calls for polymeric aluminium chemistry.

Industrial solid grades are supplied as white powder, granules or kibbled material in 25 kg PE-lined woven bags. COA, TDS and SDS are available for the offered form and lot.

Product Introduction

Aluminium Sulfate (CAS 10043-01-3), also called Aluminum Sulfate, filter alum or papermaker’s alum, is supplied as an industrial coagulant and process chemical. We offer it for water clarification, wastewater treatment, paper manufacture and selected textile or chemical-process applications. The quoted form and active-content basis are confirmed for the actual process requirement.

Applications

Industrial and municipal water treatment where aluminium sulfate is specified as a coagulant.
Wastewater clarification and suspended-solids removal in an approved treatment program.
Paper manufacturing for sizing, retention and process-control uses that specify alum.
Textile dyeing, finishing and selected pH-adjustment or chemical-formulation processes.
Raw material for aluminium-based industrial chemical formulations.

Offered Grade and Documentation

Commercial aluminium sulfate can differ in hydration state and physical form, so we confirm the agreed Al₂(SO₄)₃ basis, iron and insoluble-matter limits, available form, packaging and test method before supply. A batch COA, with the applicable TDS and SDS, is available for the offered grade.
