Iron Free Aluminium Sulphate 16% Al2(SO4)3 Non-Ferric Aluminium Sulfate
Aluminum sulfate (chemical formula Al2(SO4)3, formula weight 342.15), white orthorhombic crystalline powder, density 1.69g/mL (25℃). In the paper industry, it is used as a precipitant for rosin gum, wax emulsion and other rubber materials, as a flocculant in water treatment, and as an internal retention agent for foam fire extinguishers, raw materials for the production of alum and aluminum white, petroleum decolorization, deodorant, and some Raw materials for medicines, etc. It can also produce artificial gems and high-grade ammonium alum. About 50% of the total output of aluminum sulfate is used in papermaking, and the second largest use is used as a flocculant in drinking water, industrial water and industrial wastewater treatment, accounting for about 40% of the total output of aluminum sulfate. When aluminum sulfate is added to this type of water, it can produce colloidal aluminum hydroxide flakes that can adsorb and precipitate bacteria, colloids and other suspended solids, which can be used in drinking water treatment to control the color and taste of the water.

1. When used in water purification, aluminium sulfate causes impurities to coagulate into larger particles and then settle to the bottom of the container (or be filtered out) more easily. This process is called coagulation or flocculation.
2. Aluminium sulfate is used in paper manufacturing industry as paper sizing agent to increase paper's water-resistant and anti-seepage performance.
3. Aluminum sulfate is used as a mordant in the dyeing process. A mordant is a substances that aids the dye with becoming printed on a fabric or paper.
4. Aluminum sulfate has also been used to help control algae growth in ponds, lakes and waterways. Gardeners also use this acidic compound with plants to adjust the pH level particularly basic soil.
5. It has also been used in firefighting foam, deodorant, baking soda, leather making, fertilizer, soaps, drugs and chemical catalysts.
