Can I use Aluminum Sulfate in a swimming pool?

Maintaining the water quality of a swimming pool is crucial for ensuring a safe and enjoyable swimming experience. One common chemical employed for water treatment is Aluminum Sulfate, a compound known for its effectiveness in clarifying and balancing pool water.

Aluminum sulfate, also known as alum, can act as a flocculants in swimming pool water treatment, helps remove suspended particles and impurities. This can make the water clearer and enhance the beauty and overall safety of the pool.

Clarification Process:

Aluminum sulfate traps suspended particles, such as dirt, debris, and microorganisms, causing them to settle to the bottom of the pool. Regular use of aluminum sulfate helps maintain water clarity and prevents the accumulation of unwanted substances.

pH Regulation:

Besides its clarifying properties, aluminum sulfate also influences the pH levels of pool water. Ensure that the pH of the pool water is in the range of 7.2 to 7.6 and the total alkalinity is in the range of 80 to 120 ppm. If necessary, adjust pH using pH Minus or pH Plus and adjust total alkalinity using pH Minus and TA container. Never add aluminum sulfate when the pool is being used.

Considerations and Guidelines:

Proper Dosage:

It is crucial to follow recommended dosage guidelines when using aluminum sulfate in a swimming pool. The usual dosage is 30-50 mg/L. If the water is too dirty, a higher dosage is required. Excessive dosing will cause the pH value to drop excessively, causing potential harm to swimming pool equipment, and will also reduce the flocculation effect. Underdosing, on the other hand, may not provide effective water clarification.

Regular Monitoring:

Regular testing of pool water parameters, including pH, alkalinity, and aluminum sulfate levels, is essential. This ensures that the water remains within the recommended range and helps prevent any potential issues arising from chemical imbalance.

Aluminum sulfate must be used correctly according to the guidelines of use. It helps eliminate suspended particles and balance pH values, and plays an important role in clearing the water impurities of the pool. The pool should be tested on a regular basis, and follow the correct usage method to safely put the swimming pool chemicals.
