1. Good flocculation: Aluminum sulfate can form aluminum hydroxide colloids in water treatment, which have strong adsorption capacity and can cause suspended particles in water to agglomerate into larger flocs, thereby accelerating precipitation and achieving the goal of purifying water quality.
2. Widely applicable: It can be used to treat various industrial wastewater and domestic sewage, and has good effects on removing turbidity, chromaticity, heavy metal ions, etc. from water. At the same time, it is also used in multiple fields such as papermaking, textiles, printing and dyeing, and chemical engineering.
3. Low cost: Compared to some other coagulants, aluminum sulfate is relatively inexpensive and has mature production processes and a wide range of sources, making it cost-effective for large-scale industrial applications.
