Abstract: Apparatus is provided having a signal processor or signal processing module configured to receive signaling containing information about the quality of water in a ballast water tank recirculation treatment system, e.g., in a vessel, boat or ship; and determine information about a variable fluorescence treatment to the water in the ballast water tank recirculation treatment system, based at least partly on the signaling received, as well as provide corresponding signaling containing information about the variable fluorescence treatment. The apparatus may include a variable fluorescence device configured to receive the corresponding signaling and provide the variable fluorescence treatment, including providing ultraviolet (UV) light to the water in the ballast water tank recirculation treatment system.

Abstract: A system is provided having a signal processor that receives signaling containing information about a quality of water being monitored for treatment in at least one ballast tank of a ballast treatment system and a compliance set point related to the quality of the water; and determines corresponding signaling containing information to recirculate and treat the water in the at least one ballast tank of the ballast treatment system until the quality of the water being monitored achieves the compliance set point, based upon the signaling received. The signal processor also provides the corresponding signaling as control signaling to recirculate and treat the water until the quality of the water being monitored achieves the compliance set point.
