How does ultrasonic cleaning work?

To get a really good clean, you might think you have to rub away at an object with a caustic substance. However, ultrasonic cleaning proves this doesn’t have to be the case. Using a water-based system, great results and environmentally friendly cleaning can be achieved in an ultrasonic cleaning tank.

Environmental issues are big news right now and for businesses looking for a replacement for their solvent based cleaning systems should look to ultrasonic methods. A water-based system, ultrasonic cleaning uses no solvents and produces far less harmful waste than other alternative methods.

What does ultrasonic cleaning entail?

This method of cleaning uses high frequency soundwaves through water to produce millions of tiny bubbles. The soundwaves are made by passing electricity through multiple electric transducers. When the current passes through the transducers, they vibrate and create ultrasonic energy. This energy is transferred into a tank which creates the bubbles.

When the soundwaves hit the bubbles, the bubbles expand to a size where they cannot support their own weight, making them implode. This implosion process is called cavitation. The implosion causes large pressures within the water as the fluid rushes to fill in the gaps caused by the implosion. It is this action that produces a friction or scrubbing effect on the objects placed in the tank to be cleaned. The friction is able to remove even the most stubborn of substances from a solid surface, even delicate and sensitive items without doing damage. Any area in contact with the water can be cleaned in an effective yet gentle way. The cleaning is effective, even in hard to reach areas, such as joints, internal grooves and hinges.

To get most out of the system, a gentle detergent is also applied to the water. The detergent works in a similar way to a household detergent in that it helps to lift the contaminants from the surfaces. The detergent also aids the ultrasonic process. The detergents used are not solvent-based so produce no harmful waste and are completely bio-degradable.

Ultrasonic cleaning is extremely versatile and can be incorporated into any existing processes with simplicity and no high initial outlay. Should cleaning tanks already be owned, they can be adapted for ultrasonic cleaning methods by adding submersible transducers. It is the transducer that emits the soundwaves into the water. As technology evolves, ultrasonic cleaners can now be fully automated with a wash tank, rinse tank and drying system all fully automated in one unit.

Benefits for business include reductions in running costs thanks to fast cycle times. There is money to be saved from the extended life of the required detergents, which outlast solvents.
