Methods and systems are provided for enhancing the ultraviolet output of a water disinfection apparatus by: (i) maintaining the source of the UV radiation at a stable operating temperature and, (ii) facilitating an efficient transfer of microwave energy to the source of the UV radiation.

Method and system for achieving optimal UV water disinfection

There is described a water disinfection apparatus comprising a channel for defining a flow of water, and plural ultraviolet light sources, each comprising an elongate ultraviolet lamp unit comprising at least one ultraviolet bulb and defining an elongate lamp unit axis; and a microwave unit comprising a microwave energy source for exciting the at least one ultraviolet bulb. In use, at least part of the elongate lamp unit encounters the flow of water.
