Why Is Aluminum Sulfate Used in Water Treatment?

Apr 05, 2020· Aluminum sulfate serves as a coagulant and flocculating agent in water treatment, making the water easier to clean. It is mainly used in municipal water treatment plants to treat wastewater and potable water. Aluminum sulfate is also important for lake treatment and restoration.

Uses Of Aluminum Sulfate Aluminum Manufacturers

One of the most important uses of aluminum sulfate is in water treatment and purification. When added to water, it causes microscopic impurities to clump together into larger and larger particles. These clumps of impurities will then settle to the bottom of the container or at least get large enough to filter them out of the water.

ALUM TREATMENTS TO CONTROL PHOSPHORUS IN LAKES

What is alum and how does it work? ALUM (aluminum sulfate) is a nontoxic material commonly used in water treatment plants to clarify drinking water. In lakes alum is used to reduce the amount of the nutrient phosphorus in the water. Reducing phosphorus concentrations in lake water can have a similar clarifying effect by limiting the availability of

Aluminum in Water Health Effects and How to Remove

According to the same study, aluminum salts are used in water treatment as coagulants to reduce turbidity, microorganism levels, and other organic matter. The treatment process usually involves adding aluminum sulfate at "optimum pH and dosage, followed by flocculation, sedimentation, and filtration.' (Health Canada, 1993)
