Aluminum sulfate

White powder, water-soluble, odorless, acidic properties.

White powder, acidic, water-soluble. Used in water treatment, paper manufacturing, textiles. Also, a flocculant in wastewater treatment. Important in agriculture for soil conditioning, pH control in water.

Oilfield Drilling

Aluminum sulfate is sometimes used in drilling operations as a clay stabilizer, which can help to control the swelling of clays and prevent wellbore instability. It may be added to drilling fluids to improve their rheological properties, reduce fluid loss, and enhance drilling efficiency. Additionally, aluminum sulfate can be used as a component in certain types of drilling mud formulations, where it can help to control pH levels, reduce the viscosity of drilling fluids, and enhance their overall performance.

Water Treatment (Municipal & Industrial)

Aluminum sulfate, often utilized as a coagulant and flocculant, is crucial in water and wastewater treatment for its ability to clarify water by removing impurities. This compound facilitates the coagulation and flocculation stages, significantly enhancing water quality. It is also employed to control nutrient levels by removing excess phosphorus. Recognized for its cost-efficiency and adherence to safety standards, aluminum sulfate is a preferred option within the water treatment sector. Additionally, it is available in NSF-certified form, ensuring it meets strict regulatory mandates for safe water treatment practices. Its integral role in various water treatment protocols underscores its importance in achieving regulatory compliance and operational effectiveness.


Aluminum sulfate has diverse uses in agriculture. It improves soil structure, pH balance, and nutrient availability for plant growth. It acts as a coagulant in animal waste treatment, reducing ammonia levels. It is also used as a molluscicide to control snail and slug populations that damage crops. Its versatility makes it valuable for enhancing soil quality, managing animal waste, and protecting crops.

NSF®-certified versions available.
