Key Features
Water Clarification:
Aluminum Sulfate is renowned for its exceptional water clarifying properties. When added to pool water, it forms a gelatinous aluminum hydroxide precipitate that binds fine particles and impurities, promoting their easy removal through filtration. This results in crystal-clear water that enhances the overall aesthetics of the pool.
pH Regulation:
Our Aluminum Sulfate acts as a pH regulator, helping to stabilize and maintain the optimal pH level in the pool water. Proper pH balance is crucial for preventing corrosion of pool equipment, ensuring the effectiveness of sanitizers, and providing a comfortable swimming experience.
Alkalinity Adjustment:
This product aids in controlling alkalinity levels in pool water. By moderating alkalinity, Aluminum Sulfate helps prevent fluctuations in pH, maintaining a stable and balanced environment for both swimmers and pool equipment.
Flocculation:
Aluminum Sulfate is an excellent flocculating agent, facilitating the aggregation of small particles into larger clumps. These larger particles are easier to filter out, improving the efficiency of the pool filtration system and reducing the load on the pool pump.
Applications
To use Aluminum Sulfate, follow these simple steps:
Dissolve in Water:
Dissolve the recommended amount of Aluminum Sulfate in a bucket of water. Stir the solution to ensure complete dissolution.
Even Distribution:
Pour the dissolved solution evenly across the pool surface, distributing it as uniformly as possible.
Filtration:
Run the pool filtration system for a sufficient duration to allow the Aluminum Sulfate to effectively interact with impurities and precipitate them.
Regular Monitoring:
Regularly monitor pH and alkalinity levels to ensure they remain within the recommended range. Adjust as necessary.
Caution:
It is essential to follow the recommended dosage and application instructions provided on the product label. Overdosing may lead to undesirable effects, and underdosing may result in ineffective water treatment.
Our Aluminum Sulfate is a reliable solution for maintaining pristine pool water. With its multifaceted benefits, including water clarification, pH regulation, alkalinity adjustment, flocculation, and phosphate control, it ensures a safe, comfortable, and visually appealing swimming experience. Trust our premium-grade Aluminum Sulfate to keep your pool water clear and inviting.
