A Novel Method of Ultrasonic Antifouling

Power ultrasound can provide the driving force for a wide range of industrial processing and other emerging applications in environmental protection and remediation. Seaweeds like algae cause fouling on the hull or other submerged ship parts. An overview of antifouling system that uses high frequency power ultrasound waves to destroy algae, therefore prevent weed and barnacle growth, is presented. Benefits of the system along with R&D gaps have been highlighted. Eventhough some versions are commercially available elsewhere in the world, still such units are yet to be developed in India.
