Powder or granular?
Fast dissolving
Dissolves quickly in batch tanks. Best where alum is made into solution on site and dust can be controlled.
Low dust, free flowing
Easier to handle and suitable for dry feeders. Slightly slower to dissolve than powder.
What Is Aluminum Sulfate (Alum)?
Aluminum sulfate, spelled aluminium sulphate in British English, is an inorganic salt with the formula Al₂(SO₄)₃. In trade it is sold as a hydrate and graded by its aluminium oxide (Al₂O₃) content: solid alum at 17% Al₂O₃ is about Al₂(SO₄)₃·14H₂O (≈ 594 g/mol). It is made by dissolving aluminium hydroxide or bauxite in sulfuric acid. Most of the world's supply goes into drinking water and wastewater treatment as a coagulant, followed by papermaking.
| Property | Value | Why it matters |
|---|---|---|
| Appearance | White to off-white powder or granules | A yellow or brown tint usually means higher iron |
| Solubility in water | ≈ 36 g per 100 mL at 20 °C | Dissolves readily to make dosing solution |
| pH of 1% solution | About 3–3.5 | Acidic: consumes alkalinity and needs acid-resistant equipment |
| Moisture behaviour | Takes up moisture from air | Keep bags closed and dry to avoid caking |
| Thermal behaviour | Hydrate melts ≈ 86.5 °C; anhydrous decomposes ≈ 770 °C | Releases sulfur oxides at high temperature |

Aluminum sulfate names in other languages
Tenders, customs papers and buyers use many names for the same product: alüminyum sülfat (Turkish), كبريتات الألومنيوم or الشبّة (Arabic), сульфат алюминия (Russian), sulfato de aluminio (Spanish), sulfate d'aluminium (French), sulfato de alumínio (Portuguese) and Aluminiumsulfat (German). Potassium alum, sold for crafts and cosmetics, is a different compound.
Aluminum Sulfate Uses: Water Treatment, Paper and Industry
The same 17% product is used in very different ways. Pick your industry to see what aluminum sulfate does there, which form suits it and what to check on the certificate of analysis.
Aluminum sulfate for water treatment
The most widely used coagulant in drinking water and wastewater plants. Dissolved alum forms aluminium hydroxide floc that removes turbidity, colour, suspended solids and phosphate. Dose, pH, alkalinity, jar testing and the comparison with PAC and ferric chloride are covered in our aluminum sulfate for water treatment guide.
Used for
- Drinking water clarification
- Wastewater phosphorus removal
- Industrial process water
- Swimming pool flocculation
Works best at
About pH 5.5–7.5; low-alkalinity water needs caustic soda, soda ash or lime
Dose
Typically 5–200 mg/L, set by jar test
After filtration
Disinfection with calcium hypochlorite or sodium hypochlorite
Aluminum sulfate for paper and pulp
The "papermaker's alum" that fixes rosin size to fibres so paper resists water and ink spread. It also controls wet-end pH and helps retain fines and fillers on the paper machine. Mills also buy caustic soda for pulping.
Used for
- Rosin sizing
- Wet-end pH control
- Retention and drainage
- Pitch control
Form
Powder or granular, dissolved on site
Why low iron
Iron can tint white and light-coloured grades
Check on the COA
- Al₂O₃ %
- Fe₂O₃
- Free acid
Aluminum sulfate in other industries
Smaller but steady uses where consistency matters more than volume.
Textiles and leather
Mordant that fixes dyes to textile fibre; aluminium tanning of hides, alongside sodium sulfide for dehairing
Construction
Raw material for alkali-free shotcrete accelerators and some waterproofing products
Fire protection
Reacts with sodium bicarbonate in traditional chemical firefighting foams
Agriculture
Soil acidifier for blue bigleaf hydrangeas; for other acid-loving crops, elemental sulfur is usually safer
Liquid Aluminium Sulphate: Make It On Site from Solid Alum
Liquid alum contains only about 7.5–8.4% Al₂O₃, so more than half of every tonne shipped is water. We supply solid aluminium sulphate (17% Al₂O₃), which carries about twice the aluminium per tonne. Importers and plants dissolve it in their own tanks to make liquid alum at a lower cost per kilogram of Al₂O₃ delivered.

How much solid aluminum sulfate and water do you need for a batch of liquid alum?
—
Dissolve with agitation in plastic, fibreglass, rubber-lined or 316 stainless steel tanks. Strong solutions near 8.4% Al₂O₃ can crystallise in cold weather.
Bulk Aluminum Sulfate Supplier: Packing, MOQ and Loading
The minimum order is one full container load (1 FCL, 20ft or 40ft). Net weight per container depends on the packing and the shipping line's payload limit and is confirmed on each offer. As a wholesale alum supplier we also quote repeat container programmes for water utilities, distributors and paper mills.
| Packing | 20ft container | 40ft container | Best suited to |
|---|---|---|---|
| 25 kg woven PP bags, liner | ≈ 18–20 MT | ≈ 22–25 MT | Distributors, small plants, manual handling |
| 50 kg woven PP bags, liner | ≈ 18–20 MT | ≈ 22–25 MT | Municipal plants and paper mills with manual feed |
| 1 MT jumbo bags (FIBC) | ≈ 18–20 MT | ≈ 22–25 MT | Large plants with hoists or bag dischargers |

How to Choose an Aluminum Sulfate Supplier
Most problems with imported alum come from vague offers. Before you sign, check that the supplier answers all six points in writing.
- Al₂O₃ stated as a minimum"17%" on an offer and "17% minimum" in a contract are different commitments.
- Iron limit in numbersA figure such as Fe₂O₃ ≤ 0.03%, not just "low iron" or "non-ferric".
- Batch COAMeasured values that match the bags in the container.
- Form and packingPowder or granular, bag size, and net weight per container.
- Origin and SDSThe producing country and the SDS that sets the transport classification.
- Sample or inspectionA sample from the same source, or the right to inspect before loading.
Aluminum sulfate manufacturer or supplier?
SUHA International Trading is a supplier and exporter, not a producing plant. We buy directly from aluminum sulfate manufacturers and state the origin on every offer and certificate of origin. You get manufacturer-direct material, with one partner checking quality, preparing documents and booking freight from two origins. More about SUHA International
Aluminum Sulfate Price per Ton: How It Is Quoted and Compared
Aluminum sulfate is quoted in US dollars per metric ton for a named Al₂O₃ content, iron limit, form, packing and Incoterm. Prices follow the cost of sulfuric acid and aluminium hydroxide, energy and ocean freight, so every offer carries a validity date.
Compare cost per kilogram of Al₂O₃
A metric ton at 17% Al₂O₃ contains 170 kg of active oxide, so cost per kg Al₂O₃ = price per MT ÷ 170
Use the Al₂O₃ figure on the certificate of analysis. A cheaper offer at 15.6% Al₂O₃ needs about 9% more product for the same treatment, which also means more bags, freight and handling.
Aluminum Sulfate Storage and Safe Handling
Aluminum sulfate forms an acidic solution when it meets water or moisture on the skin and eyes. It can irritate skin and cause serious eye damage, so follow the SDS supplied with every order and your own site rules.
Storage
Dry, covered, ventilated warehouse, on pallets and off the floor. Keep bags closed: the product takes up moisture and cakes.
Keep apart from
Strong alkalis such as caustic soda and lime, and strong oxidizers. Solutions attack carbon steel, so use plastic, rubber-lined or stainless equipment.
Protection
Tight-fitting goggles, gloves and a dust mask when handling open product. Rinse eye contact with water for at least 15 minutes and get medical help.
Environment
Keep spills out of drains and waterways. Sweep up dry spills; neutralise solution spills before disposal under local rules.
Water Treatment Chemicals from the Same Supplier
Water plants rarely buy a coagulant alone. Consolidate your coagulant, pH and disinfection chemicals on one contract and one document set.

Aluminum Sulfate Supplier: FAQ
Who is a reliable aluminum sulfate supplier for bulk orders?
SUHA International Trading is a direct aluminum sulfate supplier and exporter with offices in Dubai and Ankara. We ship low-iron aluminum sulfate with 17% minimum Al2O3, as powder or granules, in 25 kg or 50 kg bags or 1 MT jumbo bags, loaded at Mersin (Türkiye) or Jebel Ali (UAE), with a batch certificate of analysis on every container.
What is aluminum sulfate used for?
Mainly as the primary coagulant in drinking water and wastewater treatment, where it removes turbidity, colour, suspended solids and phosphate. It is also used for rosin sizing in papermaking, as a dye mordant in textiles, in leather tanning, in shotcrete accelerators, as a soil acidifier for blue hydrangeas and as a flocculant to clear cloudy swimming pools.
What does 17% aluminum sulfate mean?
It means the product contains at least 17% aluminium oxide (Al2O3) by weight. Al2O3 is the active content buyers dose and pay for. Solid aluminum sulfate at 17% Al2O3 is the hydrate Al2(SO4)3·14H2O. Our typical lot analysis shows 17.68% Al2O3.
What iron content does your aluminum sulfate have?
Our grade is low-iron aluminum sulfate, specified at 0.03% maximum iron as Fe2O3, with 0.02% measured in our typical lot analysis. Low iron keeps treated drinking water and white paper free of colour. If your tender needs a tighter iron limit, send it with your enquiry.
Is aluminum sulfate the same as alum?
In water treatment and papermaking, yes: aluminum sulfate is commonly called alum or papermaker's alum. Chemically, alum also refers to double salts such as potassium alum, which is a different product. When buying, specify aluminum sulfate, Al2(SO4)3, and its Al2O3 content.
Is aluminum sulfate the same as aluminium sulphate?
Yes. Aluminum sulfate is the American spelling and aluminium sulphate the British spelling of the same compound, CAS 10043-01-3. The product, the HS code and the specification are the same whichever spelling a tender uses.
Do you supply liquid aluminium sulphate?
We supply solid aluminium sulphate (17% Al2O3), not liquid. Liquid alum contains only about 7.5–8.4% Al2O3, so shipping it overseas means paying freight on more than half water. Most importers dissolve solid alum on site to make their own liquid alum, which is cheaper per kilogram of Al2O3 delivered.
How do I make liquid alum from solid aluminum sulfate?
Dissolve the solid in water in an acid-resistant tank with agitation. To make about 8% Al2O3 liquid alum from 17% solid, mix roughly 47 kg of solid with 53 kg of water per 100 kg of solution. Use plastic, fibreglass, rubber-lined or 316 stainless steel equipment, because the solution is acidic.
What is the HS code for aluminum sulfate?
Aluminum sulfate is classified under HS code 2833.22 (aluminium sulphate). Many countries add further digits, so importers should confirm the full national tariff line with their customs broker.
What is the minimum order and packing for bulk aluminum sulfate?
The minimum order is one full container load (1 FCL, 20ft or 40ft). Packing options are 25 kg and 50 kg woven PP bags with a moisture-proof liner, or 1 MT jumbo bags. A 20ft container typically carries about 18–20 MT and a 40ft about 22–25 MT, confirmed on each offer.
What is the price of aluminum sulfate per ton?
Aluminum sulfate is quoted in US dollars per metric ton for a named Al2O3 content, iron limit, form, packing and Incoterm, so there is no single price. It follows sulfuric acid, aluminium hydroxide, energy and freight costs, and every offer carries a validity date. To compare offers fairly, divide the price per ton by 170 to get the cost per kilogram of Al2O3 at 17%.
Which documents come with an aluminum sulfate shipment?
Each shipment comes with a batch certificate of analysis, the safety data sheet, commercial invoice, packing list, bill of lading and certificate of origin (Türkiye or UAE). Tender documents and independent pre-shipment inspection are available on request.
How do I choose a reliable aluminum sulfate supplier?
Ask for an offer that states minimum Al2O3, maximum iron and insoluble matter, form, packing, net weight per container, origin, Incoterm and validity date. A reliable aluminum sulfate supplier sends a batch certificate of analysis that matches the bags, provides the SDS and certificate of origin, and allows a sample or independent inspection before loading.
Is aluminum sulfate hazardous?
Aluminum sulfate is not flammable, but it forms an acidic solution on contact with moisture. It can irritate the skin and cause serious eye damage, so goggles, gloves and a dust mask should be worn when handling it. The transport classification is stated on the SDS and the shipping documents.
Is aluminum sulfate good for hydrangeas?
Yes, for bigleaf hydrangeas. Aluminum sulfate lowers soil pH quickly and makes aluminium available to the plant, which turns pink flowers blue. For other acid-loving plants such as blueberries, elemental sulfur is usually the safer choice, because too much aluminium can damage roots.
Can aluminum sulfate be used in swimming pools?
Yes. It is used as a flocculant to clear cloudy pool water: it binds fine particles into flocs that sink to the floor, where they are vacuumed to waste. It lowers pH and alkalinity, so the water chemistry should be rebalanced afterwards.
