Abstract
A method to treat ballast water comprises injecting ozone into water loading into a sea faring vessel prior to charging the water into a ballast tank; and charging the ozone injected water into the ballast tank. A system for treating ballast water comprises a sea faring vessel including at least one ballast tank; an ozone generator that generates ozone, a ballast water conduit that uptakes water through a loading port of a sea faring vessel and conducts the water to load the ballast tank; and an ozone feed line that injects ozone from the generator into water in the conduit at an injection point located upstream to an intersection of the conduit with the ballast tank.
Claims43
A method of ozone treatment, comprising:
- injecting ozone into water loading into a sea faring vessel prior to charging the water into a ballast tank;
- charging the ozone injected water into the ballast tank;
- and
- adjusting a rate of injection of the ozone into the water and adjusting the rate of water loading into the vessel to provide a target biokill of species within the water.
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 uptakes water through a loading port of a sea faring vessel and conducts the water to load the ballast tank;
- an ozone feed line that injects ozone from the generator into water in the conduit at an injection point located upstream to an intersection of the conduit with the ballast tank;
- a controller operatively connected to the conduit to regulate water flow within the conduit;
- a controller operatively connected to the ozone generator to regulate injection of ozone into the water flowing within the conduit.
- a computer usable medium comprising a set of instructions to operate the water flow controller to regulate water flow within the conduit and operatively connected to the ozone generator controller to regulate injection of ozone into the water flowing within the conduit.
A method of ozone treatment, comprising:
- injecting ozone into water discharging from a ballast tank at a location downstream from the tank;
- and
- unloading the ozone injected water to the sea.
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;
- an ozone feed line that injects ozone from the generator into water in the conduit at an injection point located downstream to an intersection of the conduit with the ballast tank;
- a controller operatively connected to the conduit to regulate water flow within the conduit;
- a controller operatively connected to the ozone generator to regulate injection of ozone into the water flowing within the conduit.
- a computer usable medium comprising a set of instructions to operate the water flow controller to regulate water flow within the conduit and operatively connected to the ozone generator controller to regulate injection of ozone into the water flowing within the conduit.
A method of ozone treatment, comprising:
- injecting ozone into water loading into a sea faring vessel prior to charging the water into a ballast tank;
- charging the ozone injected water into the ballast tank;
- and
- adjusting a rate of injection of the ozone into the water and adjusting the rate of water loading into the vessel to provide a concentration of ozone of 1.0 to 4.5 mg/l in the water.
