Abstract
A method and system of ozone treatment diverts a portion of water from a flow of water in a conduit; injects an ozone-containing gas into the portion to provide an ozonated portion; recombines the ozonated portion with the flow of water in the conduit; and controls and regulates the diverted portion to provide a minimum diverted portion flow rate according to flow in the conduit and proportion of ozone in the injected gas.
Claims26
A ballast-water treatment system comprising:
- a 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 regulate the diverted portion to provide a minimum diverted portion flow rate according to flow in the conduit and proportion of ozone in the injected gas.
1 more element
A method of ozone treatment, comprising:
- determining a target biokill of species for water charging into a ballast tank of a vessel;
- diverting a portion of water from a flow of the water charging into the ballast tank;
- injecting ozone into the diverted portion at a rate determined to attain the target biokill when the portion is recombined into the water for charging to the ballast tank;
- and regulating the diverted portion of the water to a minimum diverted portion flow rate according to flow in the conduit and proportion of ozone in the injected gas.
1 more element
A ballast-water treatment system comprising:
- a sea faring vessel including at least one ballast tank;
- an ozone generator that generates ozone;
- a ballast water conduit that discharges water from the ballast tank and conducts the water to an unloading port of the sea faring vessel;
- a regulator to divert a portion of the water from the conduit;
- and an injector to provide an ozone injection rate into the portion of water;
- wherein the regulator regulates the diverted portion to provide a minimum diverted portion flow rate according to flow in the conduit and proportion of ozone in the injected gas.
