Pool Water Treatment: Effective Removal of Sediments

Pool water treatment is a crucial step in maintaining the clarity and hygiene of aquatic environments, and the removal of sediments stands out as a paramount task. The presence of sediments not only affects water quality but may also lead to other issues. Understanding how to efficiently eliminate sediments is vital in pool water treatment. This article explores common and effective methods to ensure the continuous freshness of pool water.

Optimal Timing for Adding Treatment Agents

When applying sediment treatment, it is generally scheduled to add the treatment agent to the pool in the evening. Early the next morning, sediments are removed using a manual pool vacuum. This timing is carefully chosen for several reasons.

Delaying the treatment until late at night is avoided because, when exposed to sunlight, suspended particles in the sediments tend to resurface, impacting the effectiveness of water purification. Therefore, it is advisable to start the sediment removal process early in the morning, ensuring completion before the sun rises and maintaining the clarity and hygiene of the pool water. This strategic timing contributes to the maximized maintenance of clean and transparent water quality.

Factors in Using Pool Sediment Treatment Agents

1. Frequency of Use: Typically, pool sediment treatment agents are used every 5-7 days or when the pool water appears turbid. This helps in sustaining clear and hygienic water conditions.
2. Dosage: The recommended dosage is 5-10kg for every 1000 cubic meters of water. Ensure the proper proportion is used to achieve optimal results.
3. Water Quality Adjustment: Before adding the sediment treatment agent, it’s crucial to adjust the water pH to around 7.5. A higher pH facilitates the elimination of polar molecules in the water, making suspended particles more prone to settling. The preferred pH range for commonly used pool sediment agents (polyaluminum chloride) is 7.5 to 8.5. In an alkaline environment, polyaluminum chloride can effectively utilize its hydroxy bridge function to accelerate coagulation and settling.
4. Application Method: When using polyaluminum chloride, it should be dissolved in water first. Use a bucket containing at least 10 times the amount of water needed, then slowly add the polyaluminum chloride while stirring continuously. This ensures rapid dissolution and prevents clumping, making it easier to disperse the agent. Avoid adding water after the polyaluminum chloride, as it may lead to clumping and challenging dispersion.

Considerations in Using Pool Sediment Treatment

1. Heat Generation and Quality Relationship: Poly aluminum chloride generates heat during the dissolution process, and the higher the heat generated, the better the quality of the agent. Therefore, observing the heat produced can be an initial indicator of the agent’s quality.
2. Prompt Addition after Dissolution: Dissolved polyaluminum chloride should be added to the pool as soon as possible. This is because the effectiveness of polyaluminum chloride in the water requires timely application to achieve the desired effects.
3. Comparison of Pump and Direct Addition: Some pools use a pump to slowly add polyaluminum chloride, while others add it directly to the water inlet. Direct addition may yield better results, but it increases the workload for sediment removal. Therefore, when choosing the application method, a balance between effectiveness and workload should be considered.
4. Settling Time for Coagulants: Poly aluminum chloride, as a coagulant, requires a minimum settling time of 6 hours, and typically 6-8 hours are needed for complete settling. In some cases, especially for deep pools, a longer settling time may be required. In the upper layers of the water, the settling rate of coagulants is slower. Therefore, for deep pools, in addition to increasing the dosage of coagulants, sufficient settling time should also be considered.

Crystal clear pool water is the aspiration of every swimmer, and the removal of sediments is an indispensable element in achieving this goal. By employing suitable water treatment methods, we can effortlessly eliminate sediments from the pool, ensuring the water remains clear. Let us collectively commit to maintaining the quality of pool water, providing a safe and healthy swimming environment for everyone to enjoy in the refreshing water.
