An ultraviolet C (UV-C) disinfection device includes a UV-C light-emitting diode (LED) illuminator which includes a UV-C source module and a UV-C LED coupling module. The UV-C source module includes a heat spreader and a UV LED chip that is mounted on the heat spreader which is configured to be mounted on a printed circuit board (PCB). The UV-C LED coupling module includes a holder and a rod configured to carry a UV-C light emitted from the UV-C LED chip from a first distal end of the rod to an opposite second distal end of the rod such that the UV-C light gets leaks out from a side of the rod to deliver at least a portion of the UV-C light to a surrounding of the rod, with the rod secured with the holder positioning the rod onto the UV-C chip.

A disinfection apparatus and method is provided for disinfecting a fluid. The apparatus elements define three internal container volumes. Fluid is introduced into an entry volume where its flow is conditioned to reduce splash and slow the fluid flow. The fluid is then channeled into a disinfection volume where a disinfection unit delivers a disinfection agent to the fluid. Finally, the fluid exits the apparatus through an exit volume. In one aspect, a sink-trap is disclosed in which wastewater liquid contacts a pair of diverters. The diverters have conditioned contact surfaces that slows and spreads the liquid flow and reduces liquid splash. The wastewater then passes through a UV chamber in which it is disinfected. The liquid then exits the sink-trap. Advanced self-cleaning apparatus are additionally disclosed to clean and disinfect the sink-trap and trapped wastewater. The entire apparatus operates under computer control.
