Embodiment Construction

[0017] of the present invention figure 1 A ballast tank circulation system for one or more water storage and treatment ballast tanks 10 is shown, having a pump 66 external to the ballast tank 10 . One advantage of the external pump 66 is that it facilitates the management and repair of the ballast tank system 1 . An external pump 66 can be installed quickly and easily. One embodiment of the present invention requires that exactly two connectors hook into the pump system 66 . Repairs are easy due to easy access to pump equipment. The ballast tank circulation system 1 also includes one or more injectors 20 located within the ballast tank 10 such that the injectors 20 receive pressurized water from the external pump 66 and emit the water as high pressure jets. Eductors are used to increase the motive force of the water and thus the recirculation of water and chemicals within the ballast water. As the injector draws in the pressurized water from the external pump 66, it also d...

Abstract

A ballast tank circulation system having inlet and outlet piping and means for adding one or more halogens in controlled amounts to the water within the ballast tank. One or more eductors are positioned within the ballast tank to mix and circulate water within the ballast tank. A recirculating pump is located externally to the ballast tank to ingest water from the ballast tank and discharge a stream of pressurized water. The recirculating pump receives water from the ballast tank through an inlet line that taps into the outlet piping from the ballast tank. An outlet line transport the pressurized water to the ballast tank. The eductor draws in the pressurized water entering the ballast tank and emits a high pressure jet of water that circulates within the ballast tank thereby circulating the chemical content of the ballast water. Test streams of water from the ballast tank can be analyzed to determine the level of at least one of halogens in the test stream to provide a halogen content signal. A controller receives the signal and compares the signal to a set point indicative of the level of halogen desired within the ballast tank to maintain, increase, or decrease the amount of chemical added to the water within the ballast tank in controlled amounts.

Description

technical field [0001] The present invention relates to ballast tank cycle management systems and methods, and more particularly, to systems and methods for controlling levels of marine species and pathogens within ballast tanks. Background technique [0002] Ballast tanks containing water require the management of microorganisms and biological matter to ensure that water quality can be maintained as the ship travels from one port to another. As described in related US Patent Application No. 11 / 037,642, ballast water is pumped into tanks where it is stored to properly balance the sailing vessel. Typically ballast water is loaded in one port and transported to another port where it is emptied to the new port. There are inherent dangers in this conventional approach. [0003] Releasing ballast water loaded onto ships from remote locations can be hazardous to the environment and a danger to people and animals in new ports. The introduction of exotic marine organisms into new...
