Industrial aluminum sulfate (Al₂(SO₄)₃) is a crystal in the orthorhombic crystal system, with a density of 1.69 g/mL (25℃). Due to the presence of Fe²⁺ ions in the raw materials, industrial - grade aluminum sulfate appears light green or light yellow.

In the paper - making industry, it is used as a precipitant for sizing agents such as rosin size and wax emulsion. In the treatment of drinking water, industrial water, and industrial wastewater, it serves as a flocculant. It can also be used as the internal agent of foam fire extinguishers, the raw material for manufacturing alum and aluminum hydroxide, the decolorizing and deodorizing agent for petroleum, and the raw material for certain drugs. Moreover, it can be used to manufacture artificial gems and high - grade ammonium alum. Solubility: It is soluble in water and insoluble in ethanol, etc.

Category I: For drinking water treatment.

Category II: For industrial water, wastewater, and sewage treatment.

Packaging: It is packed in coated woven bags or inner - lined plastic bags, with a net weight of 25/50 kg per bag.
