FDC™ 100% Pure Aluminum Sulfate | Dry Alum

Aluminum sulfate is added to water to remove impurities. It makes the impurities clump together and fall to the bottom of the container holding the water in a process called flocculation. The impurities are removed when the water is filtered. This is commonly used in ponds and pools to remove algae and in sewers to remove pollutants.
