First Claim
Patent Images
1. A ballast-water treatment system without an off-gas destruction device;
- comprising;
a salt water or fresh water sea faring vessel including at least one ballast tank and at least one conduit conveying water to or from an intake/outlet to the ballast tank;
a regulator to divert a portion of the water from the conduit;
an injector to provide an ozone injection rate into the portion of water; and
a controller operatively connected to the regulator and the injector to adjust the diverted portion of water and an injection rate of the ozone into the portion to attain the target biokill while avoiding a release of detrimental gas into the atmosphere without an off-gas destruction device.

11. A method of ozone treatment, comprising:
-
determining a target biokill of species for water charging into a ballast tank of a sea faring vessel;
determining an injection of ozone into the water to attain the target biokill without releasing an environmentally toxic off-gas into the atmosphere. regulating a diverted portion of the water prior to charging the water into the ballast tank;
adjusting the regulating of the diverted portion of water and a rate of injection of ozone into the portion to attain the target biokill without release of an environmentally toxic off-gas; and
injecting ozone at the determined rate into the regulated diverted portion to attain the target biokill when the portion is recombined into the water for charging to the ballast tank without releasing an environmentally toxic off-gas into the atmosphere. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
