A foam stabilizer is added to the reaction to create a viable carbon dioxide layer that can effectively lock out oxygen from the burning material. This is the most common substance in many fire extinguishers used in Japan and India.

- The other common usage is water purification. Here, it reacts with metal elements in the water to form insoluble substances. These particles then sediment below the container where they can be removed through sieving. This process is called flocculation or coagulation and is common among water suppliers and bottlers.
- Textile printers use aluminum sulfate as a dye fixer or a mordant. It attached itself to the color and prevent it from running when it is being washed It can also be used to adjust the soil PH.
