A device for the UV treatment of fluids flowing in a flow channel, including a plurality of cylindrical low-pressure mercury UV emitters arranged in groups in the flow channel. The longitudinal axes of the UV emitters are disposed substantially parallel to one another such that the emitters of a given group are disposed in a plane. At least one elongated sensor arrangement monitors the operating state of the emitters, and is spaced from and parallel to one of the groups of the emitters. The sensor arrangement extends essentially transverse to the longitudinal axes of the emitters of the adjacent group, and is provided with a separate UV sensor for each emitter. At least one unit connected with the sensor arrangement controls and/or regulates the emitters.

Device for the UV treatment of flowing fluids

The invention relates to a device for disinfecting liquids by means of ultraviolet radiation in a continuous flow method, with a reactor chamber through which flow can take place and in which a number of UV radiator units is arranged, the reactor chamber being provided with a wall, which is open at two end sides, and locally surrounded by at least one pre-chamber. Advantageous flow conditions are achieved if the at least one pre-chamber is welded to the wall at a distance from the end side so that an annular intermediate space with an internal width (r) is formed between a side of the per-chamber and the wall, and an essentially axisymmetric annular gap (d) is formed between the end side and the pre-chamber.
