A sterilizing apparatus is disclosed. A sterilizing apparatus according to one embodiment comprises: a cover main body unit having an accommodation space formed therein so as to accommodate a device to be sterilized, wherein the accommodation space is open toward a bottom surface on which the device to be sterilized is disposed; an ultraviolet light emitting diode provided on a surface facing the bottom surface of the cover main body unit, and turned on so as to emit ultraviolet rays toward the accommodation space; a power supply unit for supplying power to the ultraviolet light emitting diode so as to turn on the ultraviolet light emitting diode; and a control unit for controlling an operation of the power supply unit.

Water quality maintenance system are disclosed herein. The systems are configured to automatically switch between an open state allowing for purging of water from a water line and a closed state preventing water flow. The systems comprise a controller is configured to automatically generate a control signal and a purge valve comprising an electromagnetic actuator in electromechanical communication with the controller. Also disclosed herein are fixtures comprising the systems and methods of using the systems.

A device for disinfecting the interior of a drain pipe having a tubular wall formed with a hole between the sink drain inlet and the U-shaped trap. A UV-C LED module is positioned to register with the hole and includes a UV-C LED that generates a radiation beam having a predetermined radiation angle to transmit UV-C light into the drain pipe through the hole to irradiate at least a portion of said interior surface and expose airborne pathogens contained therein to UV-C light. A lens generally coextensive with the tubular wall has a peripheral edge aligned with the hole. The UV-C LED is spaced from the lens a distance to cause the radiation beam to extend up to but not beyond the peripheral edge of the lens to maximize transmission of UV-C light through the lens to maximize exposure of the interior surface and airborne pathogens to the UV-C light.

A fluid treatment and disposal system includes a sink, having a basin, a sink drain inlet, and a sink drain trap. An open cavity is disposed behind a rearward wall of the sink basin, between a top portion of the sink and the sink drain trap. A curved transition surface receives fluid entering the sink. Embodiments of the drain are shaped to promote the evacuation of fluid from the basin while limiting turbulence. An exhaust port fluidly coupled with the open cavity evacuates the open cavity and surrounding environment. Embodiments optionally associate one or more of the following with the open cavity: Ultra-Violet (UV) Germicidal Lights, and Ozone water, copper-silver ionization, and/or sanitizing agent injection systems.
