Answer: There are important guidelines to follow when using UV disinfection systems for drinking water treatment in Germany. According to a statement from the Federal Health Office, only type-tested systems should be used for drinking water applications and it is recommended that a sensor should be available to display the irradiance. The systems in the Aquada series from WEDECO, which also includes the Altima, meet the technical requirements, but are not certified by the DVGW (German Gas and Water Association). In contrast, the devices in the Spektron series from WEDECO are DVGW certified. If you want to use a system from the Aquada series in your household, you should therefore coordinate in advance with the responsible authority, such as the health department, to ensure that the use of the device is recognized. In addition, the Federal Health Office points out that UV irradiation alone does not ensure disinfection of the distribution system (such as water pipes). If there is existing contamination in the pipe network or house installation, disinfection with chlorine is necessary. In this context, we recommend flushing the pipes with our Baxero product to ensure that the pipes are germ-free. This flushing can be repeated annually if necessary to ensure consistently high water quality.
