Buyer intent coverage
Aluminium sulfate (alum) — what it is, where it is used, how it is chosen
Aluminium sulfate is the workhorse inorganic coagulant of water treatment, supplied as a solid (kibbled, ground or slab) or as a clarified liquid solution. It destabilises suspended colloids so they flocculate and settle, and it is equally central to paper sizing chemistry, where it fixes rosin and retention aids to the fibre.
Primary uses
- Coagulation and turbidity removal in drinking-water treatment
- Phosphorus removal in municipal wastewater
- Rosin sizing and retention control in paper manufacturing
- Colour and organics removal from surface water
Applications
- Municipal drinking-water and wastewater plants across Canadian provinces
- Pulp and paper mills in the Quebec, Ontario and British Columbia forestry clusters
- Industrial process-water clarification and effluent polishing
- Textile and dyeing effluent treatment
- Lake and pond phosphorus inactivation programmes
Advantages
- Long-established, well-understood dose-response in conventional clarification
- Lower unit cost than most speciality polymeric coagulants
- Liquid form eliminates on-site dissolving and dust handling
- Effective on both turbidity and phosphorus with a single chemical
Limitations to consider
- Consumes alkalinity and depresses pH, often requiring a companion alkali
- Performance falls off in cold water compared with polyaluminium chloride
- Generates a higher sludge volume than some alternatives
- Solutions are corrosive to unprotected mild steel and concrete
How to choose the right grade
- Run a jar test on your own raw water before switching coagulants
- Decide between solid and liquid based on storage, dosing equipment and site handling capability
- Confirm the alumina content basis so offers can be compared on active strength
- For drinking water, confirm the potable-water certification your regulator requires
Typical grades
- Solid kibbled or ground, iron-free and standard
- Liquid solution at standard alumina strength
- Paper-grade alum
- Drinking-water certified grade
Comparable materials — how Aluminium sulfate (alum) sits against alternatives
- Polyaluminium chloride for cold-water and lower-sludge performance
- Ferric chloride or ferric sulphate for phosphorus removal
- Organic polymer coagulants as a partial replacement
Comparable-material reference. Grade selection is confirmed at RFQ against your process.
Procurement coverage
How to specify, order and receive Aluminium sulfate (alum)
Written for procurement, quality and technical buyers in Canada and the United States. No numeric price, MOQ, stock or lead-time value is published — those are confirmed per shipment in the quotation and against the confirmed batch.
How buyers specify at RFQ
- Alumina content and free acid
- Iron content and insoluble matter
- Solid form and particle size, or solution density and strength
- Potable-water certification where required
Packaging options (industry-standard)
- 25 kg bag or FIBC bulk bag for solid grades
- IBC tote for liquid solution
- Bulk tanker delivery for municipal plants with tank storage
- Packaging options and available pack sizes are confirmed with each quotation.
Storage & handling
- Store solids dry; the material is hygroscopic and hardens if exposed
- Use corrosion-resistant tanks, pumps and containment for solutions
- Protect liquid storage from freezing, which causes crystallisation in lines
Documentation available
- Technical data sheet (TDS) for the offered grade
- Safety data sheet (SDS) in the format required for Canadian import
- Certificate of analysis (COA) against the confirmed batch
- Drinking-water certification documentation where the grade supports it
- Documentation is confirmed per batch at quotation; availability depends on the grade and supplier offered.

Technical & procurement detail
Where aluminium sulfate is used+
Aluminium sulfate is a widely used inorganic coagulant supplied in solid and liquid forms. Alumina content and form are confirmed with the supplier at quotation.
Application areas are quoted separately+
Municipal water, industrial process water, wastewater, boiler and cooling water, reverse osmosis and swimming pool applications are treated as distinct specifications. Products supplied for one of these duties are not presented as interchangeable with another. State the intended application in your enquiry so the correct specification is reviewed with the supplier.
How specifications are confirmed+
Allzone does not publish assumed purity, concentration, active content, packaging, origin, certification or regulatory approval values. The grade, specification and documentation are confirmed in writing against supplier technical data sheets and safety data sheets before an order is placed. Request the technical data sheet and safety data sheet for the exact grade under consideration.
Frequently asked questions
