How to adjust the circulation cycle at peak season?

Normally,the circulation time of swimming pools is every 6 hours. But the time should be shortened during the summer peak season .

Why must the circulation cycle be shortened?

   1, The standard six-hour cycle is designed based on typical customer traffic.While during peak periods, customer density doubles or even triples, causing the  rate at which contaminants enter the water to far exceed design specifications.

   2, A clear chain of cause and effect exists: excessively long circulation cycles lead to filtration failing to keep pace, causing turbidity to spike and water quality to deteriorate, ultimately resulting in a surge of complaints.

So that how can we do during the summer peak season?

• (1), During peak periods, it is recommended to shorten the circulation cycle from 6 hours to 4 hours—effectively increasing the circulation volume by 50%.
• (2), The backwashing frequency should be increased accordingly.During peak periods, it is recommended to backwash every 2–3 days (compared to the usual 5–7 days) to prevent filter media clogging and a consequent drop in filtration efficiency.Meantime,Check the pressure differential of the filtration system before peak periods; backwash if the differential exceeds 0.05 MPa.Don’t wait until the scheduled cycle time to perform the backwash.
• (3), During wave generation, the water in the wave pool churns violently, stirring up bottom sediments; the load on the circulation system far exceeds that of a static water state, necessitating an additional 10%–15% increase in circulation capacity.
• (4), Where multiple pools share a common equipment room, priority is given to maintaining circulation rates for the main pool and high-load pools during peak periods, while the rate for leisure pools may be appropriately reduced.
• (5), Set the pump frequency to high one hour in advance.Don't wait until the water quality deteriorates before increasing the speed.
• (6), Can use the invert water pumps: increasing the frequency during peak periods accelerates circulation, while lowering it during off-peak periods saves energy, resulting in an overall energy saving of 25%–40%.
• (7), For high-load areas such as wave pools and slide splash pools, the recommended circulation cycle is 2 to 3 hours.
