Often encounter customer consultation, my swimming pool to choose how large sand filter?
Calculate the circulation flow of the pool.
When customers seek advice on selecting a sand filter for their swimming pool, it's important to consider factors like pool size and filtration cycle. To determine the right filter size and quantity, follow a simple calculation method. Start by calculating the pool's water capacity with the formula:
V = length × width × average depth.
Then, find the circulation flow using Q = pool water capacity × 1.05 / 4h, assuming a 4-hour circulation cycle.
For instance, for a pool measuring 25 meters in length, 16 meters in width, and with an average depth of 1.4 meters, the water volume would be 560 m³. With a 4-hour filtration cycle, the circulation flow would be 147 m³/h.
Medium-speed filtration&High-speed filtration.
With the circulation flow known, you can determine the appropriate sand filter size. For a circulation flow of 147 m³/h and a medium-speed filtration rate of 25 m/h, consider using four sand cylinders with a diameter of 1400 mm (unit: mm) to meet specific demands.
Understanding filtration rates is essential for effective filter performance. Filtration rate categorizes filtration into low-speed ( V ≤ 10 m/h), medium-speed (11-30 m/h), and high-speed (31-50 m/h) filtration. Optimal filtration usually occurs within the 10-25 m/h range, ensuring efficiency and minimal pressure loss. Exceeding 25 m/h can compromise filtration quality, leading to diminished water clarity and hygiene. Therefore, it's recommended to maintain a filtration speed ≤ 25 m/h to uphold water quality standards in public swimming pools.
