Abstract: An ultraviolet-based disinfection system is presented here. The system includes a fluid flow tube configured to accommodate fluid to be treated, and an ultraviolet energy source adjacent to the fluid flow tube. The ultraviolet energy source is configured to emit ultraviolet energy for treating fluid flowing within the fluid flow tube. The fluid flow tube is configured to inhibit open channel flow conditions and to promote plug flow conditions.

Abstract: A method of controlling the operation of a plurality of ultraviolet lamp fixtures in an ultraviolet fluid disinfection system is presented here. The method begins by detecting an operating state, condition, or characteristic of the system. In response to the detecting, the method determines an appropriate lamp regulation scheme to be applied to the plurality of ultraviolet lamp fixtures in the system. The system can then apply the determined lamp regulation scheme to individually regulate operation of the plurality of ultraviolet lamp fixtures.

Abstract: A system having a host device and a lamp fixture is presented here. The host device includes a lamp receptacle and a host controller coupled to the lamp receptacle. The lamp fixture includes a lamp bulb body, an electrical interface, and a memory circuit coupled to the electrical interface. The electrical interface of the lamp fixture and the lamp receptacle of the host device are physically and electrically compatible with each other. The memory circuit is configured to store operating data associated with the lamp fixture, and the host controller is configured to operate the lamp fixture and to manage data reading and writing operations that involve the memory circuit.
