Abstract
A fluid treatment system is disclosed that includes a control unit that controls the overall operation of the fluid treatment system. A ballast circuit is coupled with an electromagnetic radiation emitting assembly. In the preferred fluid treatment system, the ballast circuit is inductively coupled with the electromagnetic radiation assembly. The inductively coupled ballast circuit inductively energizes an electromagnetic radiation emitting device that is located in the electromagnetic radiation emitting assembly in response to a predetermined electric signal from the control unit. In addition, the fluid treatment system includes a radio frequency identification system that is used to monitor various functional and operational aspects of the electromagnetic radiation emitting assembly and a filter assembly used in the fluid treatment system.
