Prevents expensive repairs
MIC (Microbiological Influenced Corrosion) is caused by a bacterium that rapidly corrodes metal parts by using sulfur. Research into MIC corrosion is done by TNO, among others. More information about this in a TNO brochure.
With ultrasound, bacteria can be effectively controlled, as concluded in a literature study conducted by the University of Utrecht, called “Ultrasound as a sterilization method“. This concludes: “Bacteria are generally killed very effectively by sonication and cavitation” (page 26).
An ultrasonic unit placed in the tank ensures that the bacteria that cause the corrosion are controlled.
One of the applications is combating MIC in monopiles of wind turbines at sea.
Also applicable for fresh water tanks.
