UV treatments allow the quality of stored water to be maintained. So the water doesn’t turn green.

To achieve this, the UV reactor must be correctly sized. The most important criterion for algae treatment is the dose applied:

• 30 mJ/cm²

The next step is to circulate the water through the UV reactor.

In this configuration, good recirculation is essential. Size your pumping system according to the temperature of your water:

• Temperature / 2 = pumping time.
• Temperature > 28° = continuous operation

Example for a 100 m³ basin: for water at 22 degrees, the recommended recirculation time is 11 hours. The pumping rate is 100 / 11 = 9.1 m³/h.

Now you know the flow rate and dose to choose, all you have to do is fill in the form.
