Aluminium Sulphate (Powder)


Being a quality driven company we are actively engaged in manufacturing and exporting  a best quality range of ALUMINIUM SULPHATE that can be used as a flocculating agent in the purification of drinking water, waste water treatment plants, and also in paper manufacturing.

ALUMINIUM SULPHATE, alternatively spelt ALUMINIUM SULPHATE, ALUMINIUM SULPHATE (non-ferric), or ALUMINIUM SULPHATE; is a chemical compound with the formula Al2(SO4)3. ALUMINIUM SULPHATE is mainly used as a flocculating agent in the purification of drinking water and waste water treatment plants, and also in paper manufacturing.

Uses of Aluminium Sulphate

Aluminium sulphate has many different uses in day-to-day life, as well as being used in several essential industries. In fact, you probably come into contact with it on a daily basis without even knowing it.

Household Uses

Some of the most common uses of aluminium sulphate are found within the home. The compound is often found in baking soda, although there’s some controversy over whether it’s appropriate to add aluminum to the diet. Some antiperspirants contain aluminum sulfate because of its antibacterial properties, although as of 2005 the FDA does not recognize it as a wetness reducer. Finally, the compound is the astringent ingredient in styptic pencils, which are designed to stop small cuts from bleeding.


Other interesting uses of aluminium sulphate around the house are in gardening. Because aluminum sulfate is extremely acidic, it’s sometimes added to very alkaline soils to balance the pH for plants. When the aluminium sulphate comes into contact with water, it forms aluminum hydroxide and a much diluted sulfuric acid solution, which alters the soil acidity. Gardeners who plant hydrangeas apply this property to change the flower color (blue or pink) of the hydrangeas since this plant is very sensitive to soil pH.

Water Treatment

One of the most important uses of aluminium sulphate is in water treatment and purification. When added to water, it causes microscopic impurities to clump together into larger and larger particles. These clumps of impurities will then settle to the bottom of the container or at least get large enough to filter them out of the water. This makes the water safer to drink. On the same principle, aluminum sulfate is also sometimes used in swimming pools to decrease the cloudiness of the water.

Dyeing Fabrics

Another one of the many uses of aluminium sulphate is in dyeing and printing on cloth. When dissolved in a large amount of water that has a neutral or slightly alkaline pH, the compound produces a gooey substance, aluminium hydroxide. The gooey substance helps dyes stick to the cloth fibers by making the dye water insoluble. The role of aluminium sulphate, then, is as a dye “fixer,” which means that it combines with the molecular structure of the dye and the fabric so the dye doesn’t run out when the fabric gets wet.

Paper Making

In the past, aluminium sulphate was used in making paper, although synthetic agents have mostly replaced it. The aluminum sulfate helped to size of the paper. In this process, aluminum sulfate was combined with rosin soap to change the absorbency of the paper. This changes the ink-absorbing properties of the paper. Using aluminium sulphate means that the paper was made under acidic conditions. Use of synthetic sizing agents means that acid-free paper can be produced. Acid-free paper does not break down as fast as paper sized with acid.

Though you may not have known it, aluminium sulphate is used to make many products you use daily. Even the water you drink is filtered using aluminium sulphate!
