A UV-lamp is used for the disinfection of a water flow. The liquid is pumped over the UV-lamp while the UV-rays (more precisely UV-C with a wavelength between 250-270 nm) have a disinfecting effect on the water.

The dosing of ozone, a strong oxidative compound, provides an intense disinfection of the liquid. This requires the necessary precautions.

Alongside the dosing of ozone, dosing of H2O2 is often used as disinfection. Here hydrogen peroxide is added to the liquid by means of a dosing pump.
