Aluminum sulfate is a versatile chemical widely used in various industrial and commercial applications. It serves as a flocculating agent in water and wastewater treatment, aiding in the clumping of particles for easier removal of impurities. In the paper industry, it acts as a filler and binder, contributing to the production of high-quality paper. Available in liquid and dry forms, aluminum sulfate comes in different grades such as Low Iron Grade, Water Treatment Grade, and Industrial Grade, making it a crucial chemical with diverse uses.

Aluminum Sulfate Uses in Water Treatment
Aluminum sulfate is a coagulant used in water treatment to cause suspended particles in water to clump together, or flocculate. This makes it easier to remove the particles from the water through sedimentation or filtration. Aluminum sulfate is used in water treatment for a variety of purposes, including turbidity removal, color removal, phosphorus removal, and microorganism removal. It is a safe and effective coagulant for water treatment and is widely used in municipal water treatment plants. The amount of aluminum sulfate used in water treatment depends on the turbidity and other impurities in the water. Aluminum sulfate is typically added to water in a solution form and the flocculation process can take several hours to complete. After flocculation, the water is typically settled and filtered to remove the coagulated particles. Order aluminum sulfate from Water Solutions Unlimited.
