Abstract: The device (10) for degassing and the sterilization of liquids for water treatment, comprises a housing (12) with a liquid inlet (16) and an liquid outlet (18) for a passage of liquid, an ultrasonic source for delivering ultrasound in an inside of the housing, a container from ultraviolet permeable material arranged partially in the inside the housing, an adjustment device suitable to change the position of the container relative to the ultrasonic source and an ultraviolet light source (20) in the container for delivering the UV-light to the fluid passing through the inside of the housing. The device (10) for degassing and the sterilization of liquids for water treatment, comprises a housing (12) with a liquid inlet (16) and a liquid outlet (18) for a passage of liquid, an ultrasonic source for delivering ultrasound in an inside of the housing, a container from ultraviolet permeable material arranged partially in the inside of the housing, an adjustment device suitable to change the position of the container relative to the ultrasonic source, an ultraviolet light source (20) in the container for delivering the UV-light to the fluid passing through the inside of the housing, a first grouping with the ultrasonic source arranged to the housing for delivering the ultrasound to the fluid and to the container, a control arranged to synchronize the ultrasound of the first grouping together in frequency, phase and/or amplitude, a valve arranged to allow gases from the inside of the housing, and a sieve or a funnel arranged in the housing, so that a collector chamber is defined by the sieve or funnel and an inner wall of the housing. The collector chamber is controllably communicated over the valve with the surroundings. The ultrasonic source is fitted to or in the housing. The first grouping is arranged close to the liquid inlet and upstreamly relative to a second grouping. The housing has a longitudinal form, which defines a longitudinal axis. The first grouping comprises several ultrasonic sources, which are arranged in several plains in longitudinal direction of the housing spatially to each other in vertical to the longitudinal axis of the housing. The ultrasonic sources in each plain are arranged in the circumferential direction of the housing staggered to each other. The second grouping has three ultrasonic sources, which are arranged in circumferential direction and in longitudinal direction of the housing. The housing consists of stainless steel and is partially intended with an antibiotic coating having noble metal on the inside of the housing. The adjustment device is suitable to turn the container relative to the housing and has a drive operated electrically or mechanically. The housing has a first hollow cylinder and the container has a second hollow cylinder, which is concentrically arranged to the first cylinder. The liquid inlet and the outlet are arranged vertically to the longitudinal axis of the housing. The UV-permeable material has quartz.
