Description:

Aluminium sulphate is used as a coagulant in Water Treatment to remove particulates like dissolved organic carbon which maybe suspended in the medium. After coagulation, the alum acts as a flocculant allowing particles to cling together forming larger particles which in turn fall from suspension and settle in the bottom of sedimentation tanks. Clean water is taken from the top via a fall and finally moved to the disinfection stage of the plant.

Aluminium Sulphate is used in the treatment of raw water in the supply of either potable water or industrial process water, also used to treat waste water and in sludge treatment at waste water treatment plants

Application:

Water Treatment

One of the most important uses of aluminum sulfate 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 aluminum sulfate 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, aluminum hydroxide. The gooey substance helps dyes stick to the cloth fibers by making the dye water insoluble. The role of aluminum sulfate, 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, aluminum sulfate 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 aluminum sulfate 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.
