Abstract

Apparatuses for treating liquids by radiation, in particular UV radiation, possess treatment paths (10, 11) having light-permeable inner tubes (30) which receive UV lamps (32) and round the outside of which the liquid to be treated flows. The liquid contact causes the outer walls of the inner tubes (30) to become dirty, as a result of which the inner tubes (30) lose their light permeability and the efficacy of the treatment is impaired. It is therefore necessary to clean the inner tubes (30). The cleaning devices used for this purpose have the disadvantage that no treatment of the liquid can take place while the inner tubes (30) are being cleaned. In the apparatus according to the invention, the cleaning device is constructed in such a way that it possesses mechanically driven cleaning rings (34) which only partially fill the cross-section of the treatment compartment (31) of the treatment paths (10, 11). This enables the cleaning rings (34) to slide in opposite directions on the inner tubes (30) during the treatment of the liquids, because the liquids to be treated can flow past the cleaning rings (34). The invention is particularly suitable for the oxidation by ultraviolet radiation of organically contaminated liquids. <IMAGE>
