Patent ID: 7514008

Claim:
A method for water treatment, comprising: providing a conduit for conducting water from a water source on board a watercraft wherein said water source includes at least one of grey water or black water; obtaining an amount of water to be treated from said water source, said amount of water having an oxidation reduction potential; measuring a first oxidation reduction potential of said water at a first measuring point and communicating the first oxidation reduction potential to a computer; conducting said amount of water to at least one oxidant injection point downstream of the first measuring point; introducing an effective amount of at least one oxidant via an oxidant dispenser and controller communicating with the computer, at said at least one oxidant injection point, to said volume of water, said oxidant injection point being located downstream of the point of measuring the first oxidation reduction potential of said water; providing a first target oxidation reduction potential in the computer, said first target oxidation reduction potential being greater than said first oxidation reduction potential; allowing for a first oxidation-reduction reaction to occur, said first oxidation reduction reaction proceeding between said at least one oxidant and at least one contaminant in said amount of water; measuring a second oxidation reduction potential of said water at a point downstream of a point of commencement of said first oxidation-reduction reaction and communicating the second oxidation reduction potential to the computer; introducing an effective amount of at least one neutralizing chemical into said water via a neutralizing chemical dispenser and controller communicating with the computer at a neutralizing chemical injection point located downstream of a point of measuring the third second oxidation reduction potential of said water, said effective amount being based upon said second oxidation reduction potential and a target effluent oxidation reduction potential provided in the computer; allowing for a second oxidation-reduction reaction to occur, said second oxidation reduction reaction proceeding substantially between remaining said at least one oxidant and said at least one neutralizing chemical; allowing for said target effluent oxidation reduction potential to be established in said water; and distributing resultant treated water now having said target effluent oxidation reduction potential.
