SHIP BALLAST WATER ULTRASONIC TREATMENT

ballast water is circulated through a ballast treatment system and is treated by applying ultrasonic frequencies to the water to kill organisms entrained in the water, preventing the introduction of non-indigenous species between ports-of-call. A pump (17) is connected to a tube (31) lined with a pi...

Zusammenfassung:	ballast water is circulated through a ballast treatment system and is treated by applying ultrasonic frequencies to the water to kill organisms entrained in the water, preventing the introduction of non-indigenous species between ports-of-call. A pump (17) is connected to a tube (31) lined with a piezoelectric material for aiding in transmitting the ultrasonic frequencies connected to one or more ballast tanks (11) of a ship. Spatially-controllable, continous constructive interference zones may be generated within the piezoelectric-lined tubes to specifically target the particular organisms entrained within the ballast water being treated. The treatment system includes a transducer pipe (31) connected to diffusers (43) and shrouds (45). Ballast water is supplied through inlets (57) in the shrouds (45) into the diffuser (43) which circulate the water through the tube (31) which is lined with piezoelectric transducer material and then exhausted after treatment. Selon l'invention, l'eau de ballast est circulée à travers un système de traitement consistant à appliquer des fréquences ultrasonores à l'eau afin de tuer les organismes entraînés, empêchant ainsi l'introduction d'espèces non indigènes entre les escales. Une pompe (17) est reliée à un tube (31) recouvert de matériau piézoélectrique facilitant l'émission des fréquences ultrasonores, ce tube étant connecté à un ou à plusieurs ballasts (11) d'un navire. Il est possible de produire, dans les tubes à revêtement piézoélectrique, des zones d'interférences constructives continues, spatialement maîtrisables, afin de cibler spécifiquement les organismes particuliers entraînés avec l'eau de ballast en traitement. Le système de traitement comprend un conduit transducteur (31) connecté à des diffuseurs (43) et à des gaines (45). L'eau de ballast arrive dans le diffuseur (43) par des entrées (57) pratiquées dans les gaines (45), puis circulée dans le tube (31), recouvert de matériau piézoélectrique, et renvoyée après traitement.
