Abstract: The invention relates to a device for irradiating a liquid with electromagnetic radiation, in particular for sterilizing an in particular flowing liquid by means of UV radiation (UV reactor), comprising a container having an inlet for receiving the liquid and having an outlet for releasing the liquid from the container, wherein within the container a variable or adjustable irradiation zone is provided for irradiating the liquid with electromagnetic radiation, in particular UV radiation, emitted by a radiation source. In the irradiation zone the liquid is configured in the form of a liquid layer having the layer thickness which extends between the underside of the container and a gas bubble expanding above the liquid layer.

Abstract: The invention relates to a device for sterilising a fluid flowing therethrough, said device comprising: a container having an inlet for receiving the fluid and having an outlet for discharging the fluid from the container; a body having a surface which is at least in part curved, the body being positioned within the container in such a way that the fluid flowing into the container via the inlet washes over or around at least part of said body at least in the region of its surface that is curved. The device also comprises a plurality of LEDs which are each designed to emit light having wavelengths in the range of UV radiation, preferably UV-C radiation. The LEDs are designed to irradiate the fluid washing over or around the curved surface of the body with the UV radiation of the LEDs.

Abstract: An apparatus for sterilizing a liquid comprises a container (10) having an inlet (12), an outlet (14) and an interior (16) with an outer wall (18), and at least one light source (32) which is adapted to emit radiation in the ultraviolet wavelength range, in particular UV-C radiation, through the outer wall (18) into the interior (16), the outer wall (18) of the interior (16) for this purpose being configured to be at least partially transparent. The inlet (12) comprises at least one opening (28), which is positioned and aligned in relation to the outer wall (18) of the interior (16) and the at least one light source (32) in order, when a pressure is exerted on the liquid to be admitted through the at least one opening (28) and to be sterilized, to form a liquid jet (30) directed onto the outer wall (18) in a region of the at least one light source (32) and/or above the latter, and/or to form a liquid film (31) there. The liquid jet (30) impinging on the outer wall (18) may, for example, flow down thereon as a thin liquid film (31) in front of the at least one light source (32) and thereby lead to effective sterilization even with a low penetration depth of the UV radiation.
