Description

Product Detail

Aluminium Sulphate (Alum) 17% Industrial Grade

Aluminium Sulphate, commonly known as Alum, is an inorganic aluminium salt widely used as a coagulant in water and wastewater treatment and as a process chemical in several industrial applications.

Our Aluminium Sulphate is supplied for industrial and commercial applications where controlled coagulation, floc formation and suspended-solid removal are required. The product is available in solid form and can be supplied in standard industrial packaging suitable for bulk transportation and storage.

The principal chemical identifier is CAS 10043-01-3, with the chemical formula Al₂(SO₄)₃.

Product Highlights

Aluminium Sulphate based industrial coagulant
Al₂O₃ content: 17% minimum
White to off-white crystalline solid
Suitable for water and wastewater treatment applications
Available in bagged and jumbo-bag packaging
Suitable for bulk industrial supply
Batch-specific COA available according to commercial arrangement
TDS and SDS documentation available subject to product specification

Water Treatment

Aluminium Sulphate is commonly used as a primary coagulant in water-treatment processes. When added to water under controlled treatment conditions, aluminium species hydrolyze and participate in coagulation and flocculation, helping destabilize suspended particles and promote their aggregation.

This makes Aluminium Sulphate suitable for applications involving turbidity reduction, suspended-solid removal and clarification.

Dongkwang Poland's public water-treatment portfolio similarly describes Aluminium Sulphate (Alum) as a primary coagulant for turbidity removal in municipal and industrial water-treatment applications.

Industrial Applications

Depending on grade and customer requirements, Aluminium Sulphate is also used in:

Pulp and paper processing
Paper sizing
Textile processing
Dyeing processes
Leather processing
Industrial wastewater treatment
Municipal wastewater treatment
General coagulation and clarification processes

Application suitability should be confirmed against the customer's process conditions and required regulatory/quality standard.

Product Quality

Each commercial shipment should be supplied against the agreed product specification. Batch-specific Certificate of Analysis documentation can be provided where applicable.

Customers requiring a specific specification for aluminium oxide content, iron content, water-insoluble matter, pH or trace metals should state their requirements before order confirmation.

Supply & Packaging

Aluminium Sulphate can be supplied in 25 kg and 50 kg bags as well as larger jumbo-bag formats, subject to order quantity and packaging availability.

Packaging should be kept intact during transportation and protected from moisture.

Commercial Supply

Available for bulk B2B supply on FOB and other agreed international trade terms.

Pricing depends on specification, packaging, quantity, loading port and current market conditions.

* Molecular weight shown for anhydrous aluminium sulfate; commercial products may contain water of crystallization and should be specified accordingly.

** These are proposed commercial listing limits, not a claim about an actual batch. Replace them with the manufacturer's approved specification before publishing.

Recommended higher-quality version if supported by your actual COA

Parameter	Target Specification
Al₂O₃	≥17.0%
Fe₂O₃	≤0.10%
Water Insoluble Matter	≤0.10%
pH, 1% solution	≥3.0
Appearance	White crystalline powder/granules

Use the second table only if your supplier's actual TDS/COA supports these values.

ECHEMI listings demonstrate that commercial Aluminium Sulphate specifications commonly distinguish Al₂O₃, iron, water-insoluble matter and pH, with some current listings showing approximately 16–17% Al₂O₃ and limits for Fe and insoluble matter.

5. Leather Processing

Used in selected tanning and processing applications.

6. Industrial Processing

May be used wherever an aluminium salt/coagulant is required, subject to process-specific requirements.

Important compliance wording

Do not state:

"Approved for drinking water"

"Potable water certified"

"Food grade"

"FDA approved"

"EU approved"

unless you possess the specific supporting certification for the exact product and market.

PACKAGING & STORAGE

Packaging

Standard commercial options:

25 kg PP woven bags with PE inner liner
50 kg bags
500 kg jumbo bags
1,000 kg jumbo bags
Other packaging subject to commercial agreement

Storage

Store in a cool, dry and well-ventilated area.

Keep containers tightly closed and protect the product from moisture and water exposure.

Keep packaging intact during storage and handling.

It is a chemical agent used in water purification, the pH regulation of garden soil, and other commercial or industrial applications. Medically, it is primarily used as a coagulating agent in minor cuts and abrasions as well as deodorant. Aluminum (Al) is ubiquitous and represents the third most common element in the Earth’s crust. It most commonly exists in a combined state with various other elements. Al is found in materials used in the pharmaceutical industry, and in manufactured foodstuffs, cosmetics, and tap water. By overcoming the body barriers, Al may infiltrate into the blood and lead to toxic effects in liver, bone and the central nervous system.|Aluminum Sulfate Anhydrous is an aluminum salt with immune adjuvant activity. This agent adsorbs and precipitates protein antigens in solution; the resulting precipitate improves vaccine immunogenicity by facilitating the slow release of antigen from the vaccine depot formed at the site of inoculation.
