If a vessel has no cargo or is partially loaded, ballast is required to maintain its stability and safety. Water is usually used as ballast, but when collected from the source, a range of organisms enter the water, usually consisting of plankton communities, which may be a whole new ecological environment at the destination (ex situ) and may cause unnecessary biological contamination. To avoid this possible contamination, we must use an efficient system to sanitize the ballast water.

The invasive spread of aquatic organisms has been identified by the World Environmental Protection Fund (GEF) as one of the top four threats to the oceans. Can have extremely serious impacts on the environment, economy and public health. To avoid the introduction of harmful mollusks (zebra mussels, Asian clams, etc.), various ballast water sterilization treatments (also known as disinfection or neutralization) are available. A common treatment method is chemical cleaning of ballast water. The chemicals used are environmentally harmful and expensive. With the continuous increase of laws and regulations on ship ballast water management, various ballast water treatment methods, such as ultrasonic disinfection, have been integrated on ships.

Ultrasonic Ballast Water Sterilization
Ultrasonic ballast water treatment is a mechanical/physical method that avoids the use of harmful and expensive chemicals. Cavitation forces kill small aquatic organisms and microorganisms. Several studies have demonstrated that ultrasound has a high biological effect on zebra mussels, nematodes, bacteria and viruses.

Ultrasonic cavitation disinfection
High-power ultrasonic waves generate cavitation bubbles in the liquid, which lead to the creation of strong shear forces and high stresses. When intense ultrasonic waves are coupled into a liquid, the sound waves propagate into the liquid medium, causing alternating cycles of high and low pressure at a rate that depends on the frequency. During the low-pressure cycle (thinning phase), high-intensity ultrasound creates small vacuum bubbles or voids in the liquid. When the bubbles reach a volume where they can no longer absorb energy, they collapse violently during the high-pressure cycle (compression phase). This phenomenon is called cavitation. During the implosion, very high temperatures (about 5,000 K) and pressures (about 2,000 atm) are locally reached. The implosion of cavitation bubbles also leads to liquid jet velocities as high as 280 m/s.

This high-energy bubble creation and collapse causes hydrodynamic shear forces and ultrasonic oscillations that disrupt the organism's cell walls - effectively killing them. There are no known or anticipated environmental issues with regard to the impact of ultrasound-assisted technology on the environment.
