Industrial Uses of Aluminum Sulfate

Saturday , 12, June 2021 Comments Off on Industrial Uses of Aluminum Sulfate

Aluminum sulfate is a commonly used industrial chemical. Aluminum compounds, sulfur, and oxygen are often dry crystals, flours that become slimy when wet and not flammable. The solution, AL2 (SO4) 3, also known as "Alum" has been used since the ancient Egyptian era when it helped the dyeing process.

At present, aluminum sulfate is still used to help print on paper and some other industrial needs, including household products and wastewater treatment. You can find aluminum sulfate for sale for various purposes.

As Mordant

Aluminum sulfate is used as a mordant in the dyeing process. A mordant is a substance that aids the dye with becoming printed on fabric or paper. When mixed with water, aluminum sulfate creates the sludge-like aluminum hydroxide that aids textiles with the absorption of the dye. 

As a coagulant

Aluminum sulfate’s biggest industrial use is as a coagulant in water treatment plants. As treating wastewater and potable water is such an integral aspect of modern infrastructure, aluminum sulfate is used heavily. When mixed with water, aluminum sulfate takes a number of forms with different levels of ionization, which can attract pollutants in water and trigger, making it easier to clean. 

In Paper Manufacturing

Like with dyeing, aluminum sulfate has largely been replaced in the world of papermaking by modern developments, but it is still used in some paper’s pulp. The acidic chemical has been used to remove impurities from the water used to make paper.
