Abstract: A water disinfection system with a flow-through treatment chamber, a plurality of elongated ultraviolet lamps positioned parallel to each other in at least one array within the treatment chamber, and a stand-alone frame which holds in place the lamps of the array and which is constructed so that all lamps of the array can be lifted out of the chamber simultaneously. The array is disposed so that the water must pass through the array. The frame has a cuboid outer shape, an upstream end including front frame members, a downstream end including rear frame members, and a frame center section including side frame members. The array is contained inside the cuboid shape and the frame is positioned in the chamber in an unguided manner and has attachment elements for attaching the frame to a lifting mechanism.

Abstract: A mixing device for a water treatment facility with an open channel, with a base body which is designed in a plate-shape or strip-shaped manner for attachment to a wall of a channel such that a lower face which faces towards the wall of the channel during operation and an upper face which faces away from the wall of the channel during operation, whereby a plurality of protrusions is provided which extend from the base body, which are inclined away from the lower face and which extend over a plane formed by the upper face, and in that a plurality of recess is provided, and whereby each recess is arranged between two adjacent protrusions.

Abstract: A UV water treatment plant having at least one module which contains a number of elongated UV lamps in a bracket, wherein the lamps are orientated in parallel to one another, wherein a base having at least one guide connected firmly to the base and at least one guide rail connected to the bracket are provided, wherein the guide rail is mounted to be displaceable in the guide.
