## Water Filtration in a UK swimming pool## Periods Required## The Effect of the Ambient TemperatureThe safe periods of time that a filtration system on a UK swimming pool should be run for is dependent on the water temperature as shown in the following table.
## Influence of BathersTo calculate the influence of bathers using the pool on the required filtration periods just multiply the number of bathers x 2 and divide by the flow rate. So for instance 6 bathers in a pool with a flow rate of 12 m3 per hour will require an extra 2 x 6 / 12 = 1 hour of filtration. ## Number of Bathers allowedThe above rule allows the number of bathers that can use a swimming pool to be calculated i.e. Number of allowable bathers = Design Flow Rate / 2 |
