A UV lamp is often used for the disinfection of a water stream. The liquid is then pumped over the UV lamp, whereby the UV rays will have a disinfecting effect on the water. However, it is important that the liquid is fairly clear: if there are too many floating substances in the water or if the turbidity of the water is quite high, the influence of the UV lamp will be limited. The radiation is then hindered too much by the pollution present. An important advantage of UV treatment is that no chemicals are used. This eliminates the ongoing costs of reagents that occur during dosing disinfection. In addition, the chemical impact on the treated water is negligible.
In addition to the dosing of ozone, adding H202 is a frequently used disinfection method. The peroxide is added by means of a dosing pump. This leads to a relatively simple installation. The dosage can be set to dose at regular intervals or based on measurement results. H202 is often used in combination with other methods such as UV to limit consumption.
