Abstract
The object of the invention is a double-walled chamber for the UV disinfection of liquids, preferably drinking water and/or waste water. It realizes a rectangular and/or square cross-sectional shape of the UV radiation chamber even at higher pressures, whereby the radiation chamber can moreover be provided with a thin-walled configuration and allows an optimal and close arrangement of UV radiators as compared with a round chamber. By applying the inventive idea, the known dead zones at the entrance are completely eliminated and an entrance turbulence is produced which runs simultaneously with the piston flow in the chamber.
