Claim:
1. A system for treating ship or barge ballast water, comprising: a ballast tank storing ballast water; a flow sensor used to determine circulation flow or velocity of the ballast water; one or more nozzles located in the ballast tank; and one or more pumps to supply a chemical into the ballast tank and to supply water to the nozzles, the nozzles located in the ballast tank to generate a circulation current that mixes all areas of the tank without removing the ballast water from the ballast tank and conveying it to a separate mixing and treatment area located outside the ballast tank; a controller to receive a signal from the flow sensor to control the one or more pumps to enable operating the nozzles alternately and intermittently to circulate the ballast water and the mix the chemical with the ballast water; whereby the treatment system results in minimized energy consumption.
