Here are some common uses of alum:

  1. Water Treatment: Alum is widely used as a coagulant in water treatment processes. It helps to remove suspended particles and impurities from water, making it clearer and safer for consumption.

  2. Food Industry: Alum can be used as a food additive for specific purposes. It acts as a firming agent and is sometimes added to pickling solutions to maintain the crispness of fruits and vegetables.

  3. Tanning and Dyeing: Alum is used in leather tanning to enhance the absorption of dyes and improve the overall quality and texture of leather products.

  4. Paper Manufacturing: Alum is employed in papermaking as a sizing agent, which helps to improve the strength, smoothness, and water resistance of paper.

  5. Cosmetics: Alum has astringent properties, and as such, it is used in some cosmetic products like aftershaves and deodorants to help tighten the skin and reduce perspiration.

  6. Medicinal Uses: In traditional medicine, alum has been used as an antiseptic and styptic agent. It can help stop bleeding in minor cuts and wounds due to its astringent properties.

  7. Photography: Alum is used in some photographic developing processes, particularly in the production of certain types of photographic papers.

  8. Flame Retardant: Alum can be employed as a flame retardant in certain materials and textiles, reducing their flammability.

  9. Crystal Making: Alum crystals are commonly used in educational settings and science experiments to demonstrate crystal growth.


Here's a general overview of how to treat water using alum:

  1. Obtain Alum: Purchase food-grade alum or aluminum sulfate from a reputable source. Ensure that the product is suitable for water treatment purposes.

  2. Prepare Alum Solution: Dissolve a specific amount of alum powder in a clean container of water. The recommended dosage of alum varies depending on the water quality and quantity being treated. Generally, 10-100 milligrams of alum per liter of water is a common range, but it is best to consult local guidelines or a water treatment expert for precise dosage information.

  3. Stir and Dissolve: Stir the water and alum mixture thoroughly until the alum is completely dissolved. This helps to ensure that the alum is evenly distributed throughout the water.

  4. Add Alum Solution to Water: Slowly pour the alum solution into the water that needs to be treated. Stir the water gently to aid in the mixing process.

  5. Allow Settling Time: After adding alum, let the water sit undisturbed for a period of time, typically around 1-2 hours. During this time, the alum reacts with impurities, causing them to clump together and form larger particles.

  6. Sedimentation: Once the settling time has elapsed, you will notice a layer of settled particles at the bottom of the container. This sediment consists of the coagulated impurities.

  7. Decant or Filter: Carefully pour or siphon off the clarified water from the top, being cautious not to disturb the sediment at the bottom. Alternatively, you can filter the water through a fine cloth, filter paper, or a filtration system to remove any remaining suspended particles.

  8. Disinfection (Optional): After the coagulation and sedimentation process, it is advisable to further disinfect the treated water to ensure its safety for consumption. This can be done by using methods such as boiling, chlorination, or using water disinfection tablets or UV sterilization devices.
