Aluminium Sulphate (Alum) Supplier in Malaysia
- Also known as
- Aluminium Sulfate
- Aluminum Sulfate
- Al2(SO4)3
- Filter Alum
Aluminium sulphate supplier for water treatment, paper, textile, latex and industrial buyers in Malaysia. Also called alum, aluminium sulfate and filter alum, formula Al2(SO4)3, this coagulant salt is selected where plants need turbidity and colour control with a conventional aluminium sulphate dose.
Commercial supply covers water-treatment grades often specified around 17% Al2O3, plus solid flakes, kibbled lumps, granules, powder and separately specified liquid solutions. Forms do not share one packing or assay by default, so name the grade and feed method you run.
In water, aluminium sulphate hydrolyses to aluminium hydroxide floc that supports clarification ahead of settling and filtration. Paper mills use it for sizing and retention, textile dyers as a mordant, latex processors as a coagulant, and some construction formulations as an accelerator or waterproofing additive. It is not PAC, potash alum or aluminium oxide.
Send the required form or grade, target specification, quantity and delivery location with your enquiry. Availability, packing, documentation and delivery timing are confirmed with the quotation.

Aluminium Sulphate grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Water-treatment grade aluminium sulphate (17% Al2O3) | flakes, kibbled lumps, granules or powder as quoted | typically specified around 17% Al2O3 for water-treatment grades | Coagulation and clarification in drinking-water and industrial effluent plants where a water-treatment aluminium sulphate grade is specified. | Confirm the required pack format with the quotation. |
| Aluminium sulphate flakes | solid flakes | — | Dissolution and plant make-up where flake feed is preferred for handling, storage or batch charging. | Confirm the required pack format with the quotation. |
| Kibbled or granular aluminium sulphate | kibbled lumps or free-flowing granules | — | Continuous or batch dosing after dissolution where coarser solid forms suit plant feed equipment better than fine powder. | Confirm the required pack format with the quotation. |
| Aluminium sulphate powder | fine free-flowing powder | — | Faster dissolution and dry-charge applications where fine particle size supports make-up or formulation. | Confirm the required pack format with the quotation. |
| Liquid aluminium sulphate solution | aqueous solution, strength as separately specified | — | Ready-to-dose coagulation where a liquid aluminium sulphate grade is named on the plant specification rather than a solid form. | Confirm the required pack format with the quotation. |

Aluminium Sulphate applications
Safety and handling
- Classification
- irritant
Store solid material sealed in a cool, dry place and protect from moisture; damp product cakes. Keep solutions away from mild steel where practical, as aluminium sulphate solutions are acidic. Control dust and splash, and use gloves, goggles and suitable respiratory protection when handling.
Common questions about aluminium sulphate
Are aluminium sulphate, alum and filter alum the same product?
Yes. Alum and filter alum are common trade names for aluminium sulphate used in water treatment and industrial coagulation. They are not poly aluminium chloride (PAC), potash alum or aluminium oxide. State the form and any Al2O3 grade requirement in the enquiry.
What does aluminium sulphate 17% mean?
Water-treatment grades are often described by Al2O3 content, commonly around 17% Al2O3. That figure is a grade basis for the selected solid or liquid product, not a single universal composition for every form. Confirm the required assay with the specification you already use.
Which form should I request, flakes, granules, powder or liquid?
Flakes, kibbled lumps and granules are common solid feeds for dissolution. Powder dissolves faster and suits some dry-charge duties. Liquid solution is chosen when the plant specification names a ready-to-dose aqueous grade. Forms and strengths are quoted separately, so name the preferred form and dosing method.
How does aluminium sulphate differ from poly aluminium chloride (PAC)?
Both are aluminium-based coagulants, but they are different products with different dose behaviour and plant performance. If your specification names aluminium sulphate, alum or filter alum, enquire against that identity rather than substituting PAC.
Is aluminium sulphate used for water treatment and paper sizing?
Yes. Buyers use aluminium sulphate as a coagulant in drinking-water and industrial effluent treatment, and as a sizing or retention aid in papermaking. Textile mordanting, latex coagulation and selected construction formulations are other common uses. Describe the process so the suitable form and grade can be quoted.
What details are needed for an aluminium sulphate price enquiry?
Provide the form or grade, target Al2O3 or other specification, application, quantity, delivery location and any documentation or packing preference. Availability, commercial terms and delivery timing are confirmed with the quotation.
