Aluminium sulphate powder, also known as aluminum sulfate, is a white crystalline powder that is commonly used in water treatment, paper manufacturing, and various other industrial applications. It is made by reacting sulfuric acid with bauxite or aluminum ore.
In water treatment, aluminium sulphate powder is used as a coagulant to help remove impurities and suspended particles from water. It works by neutralizing the electrical charges on suspended particles, causing them to clump together and settle to the bottom of the water.
In paper manufacturing, aluminium sulphate powder is used as a sizing agent to help control the absorption and porosity of paper. It is also used as a clarifying agent to remove impurities from pulp and improve the clarity of the finished paper.
Aluminium sulphate powder is also used in various other industrial applications, including the production of synthetic zeolites, fire extinguishers, and as a flocculant in wastewater treatment.
It is important to handle aluminium sulphate powder with care, as it can be a skin, eye, and respiratory irritant. Proper protective equipment should be worn when handling the powder, and it should be stored in a dry, cool, and well-ventilated area.
