[Effect of the reflection of UV rays in the disinfection of drinking water].
The disinfection of drinking water by means of UV-rays represents an interesting alternative to chemical disinfection. However, several questions still remain to be answered, making the disinfection of drinking water by means of UV-radiation appear unsafe. The regulations concerning the disinfection performance of UV-systems are still presenting difficulties. Within the course of comparative experiments in the laboratory and using a flow-through reactor on the disinfection effectiveness of UV-radiation, it has been shown that the reflection of UV-rays can have a considerable influence on the disinfection effectiveness. In order to be able to make reliable statements on the dose-effect relation it is necessary, therefore, to record exactly the radiation applied, including the reflected proportion.
