Abstract: A disinfection device suitable for disinfection of water in a water line, wherein the device is adapted to receive water from the water line and for the disinfected water to exit the device. The disclosure also relates to a DUWL including the disinfection device, as well as a dental chair comprising the DUWL. Moreover, embodiments of the disclosure concern a method for disinfection of water in a water line.

Abstract: The present disclosure relates to device suitable for producing an aqueous liquid having a desired concentration of FAC wherein the device is adapted to receive municipal water from a municipal water supply, and for the aqueous liquid having the desired concentration of FAC to exit the device from an exit section, wherein the device comprises, a container, a mixing unit, a pumping means, an electrochemical chamber, a flow signal unit, a sterile filter unit, connecting means for transporting liquids, and a control system. In particular, water for disinfection in a desired concentration of FAC can be made using the device.

Abstract: The present invention relates to the use of an anode suitable for use in inter alia a reactor for elimination or reduction of microbial impurities from liquids, such as inter alia waste water and water intended for human or animal consumption. The anode comprises an expanded metal plate, preferably titanium, covered with a non-corrosive metal layer, preferably a platinum layer. The surface of the anode is endowed with dents, which enhances the electrochemical effect between the anode and the corresponding cathode and thereby enhances the microbial effect and at the same time reduces the energy required to obtain an efficient kill of the microorganisms.

Abstract: A dental unit water line (DUWL) monitoring and maintenance apparatus, for monitoring a DUWL. The apparatus has a cleansing unit attached to the DUWL for cleansing the fluid passing there through. A control unit controls the cleansing unit associated with the water line. A monitoring unit monitors the operation of the dental unit when used by a dentist and stores data related to that operation. A timer times and records data relating to both periods of dental unit activity and inactivity, wherein, in use, the control unit operates to receive data from the monitoring unit and the timer and, based upon that data and reference data controls the operation of the water line to control flow of fluid through that DUWL and controls the cleanser to control the overall cleansing procedures associated with both the dental unit and associated DUWL.
