50 KG/BAG Iron Free Aluminum Sulfate White Flakes for Water Treatment
The solid product of iron free aluminum sulfate is white granular or blocky, white shiny crystals. It is stable in the air. It loses part of the crystal water at 86.5℃ and loses all the crystal water at 250℃. It expands violently and becomes a sponge-like substance when heated. It decomposes into sulfur trioxide and aluminum oxide when burned to red heat. It weathers when the relative humidity is about 25% lower. It is easily soluble in water, almost insoluble in ethanol, and the solution is acidic. After long boiling, insoluble basic salts precipitate. Relative density 1.62. Iron-free aluminum sulfate is a widely used industrial reagent, which is often confused with alum (i.e. potassium aluminum sulfate dodecahydrate). Aluminum sulfate is usually used as a flocculant in drinking water purification and sewage treatment equipment, and is also used in the papermaking industry.

Uses of iron-free aluminum sulfate: Aluminum sulfate is mainly used as a paper sizing agent and a flocculant for drinking water, industrial water and wastewater treatment. It is also a raw material for producing artificial gemstones and other aluminum salts, such as ammonia alum, potassium alum, and refined aluminum sulfate. In addition, aluminum sulfate is also widely used in the production of high-quality clarifiers, petroleum deodorizing and decolorizing agents, concrete waterproofing agents, high-grade paper forging white, titanium dioxide post-film treatment, and catalyst carriers.
Aluminum sulfate decomposes when heated to generate corrosive SO3 vapor. When sulfur trioxide dissolves in water, it forms a strong acid, which has corrosive properties and reacts with strong bases, entering the human body through the respiratory and digestive tracts. It is irritating to the eyes and respiratory tract, and can cause sore throat, coughing, bloodshot eyes, and pain when inhaled; it can cause abdominal pain when ingested. People should take precautions when using it.
