Using Ultrasonic Cleaners in Disaster Restoration

Items recovered from disasters (like floods, hurricanes, and fires) are often covered with dirt, soot and mold. There are traditional cleaning methods for cleaning recovered items such as wiping, soaking in harsh chemicals or rough mechanical scrubbing. These methods may leave residue or cause damage to these items, while there's little assurance that they would come out completely cleaned.

Ultrasonic cleaning system is the ideal alternative to the traditional methods in cleaning these items.

This system works by generating ultrasonic waves and the tiny cavitation bubbles in the water (or water mixed with a mild detergent). The bubbles form and collapse in time with the frequency of ultrasonic waves. When these bubbles collapse against the surface of the items being cleaned, they create a strong cleaning and scrubbing action, knocking off and loosening dirt and contaminants from the surface.

One of the greatest advantages of ultrasonic cleaning over traditional cleaning methods is that the former cleans the items thoroughly – even items with complicated shapes and hard-to-reach holes and crevices. It cleans effectively and precisely, without the risk of damage to the items being cleaned.

Choosing the right frequency is the key for successful cleaning. For robust items with hard surfaces, opt for the low frequency (26 to 38 kHz) which produces large, energetic cavitation bubbles for the robust cleaning action. For cleaning delicate items, choose higher frequencies (450 to 950 kHz) which generates smaller bubbles for gentler cleaning.

Adding mild but specific solvents to the cleaning solution is required only for cleaning more stubborn dirt and contaminants. This is to ensure rapid and complete cleaning of the items.

How Ultrasonic Waves Are Produced for Industrial Cleaning Applications

Industrial ultrasonic cleaners deliver cleaning performance that is faster, safer, and more efficient than traditional cleaning methods that use chemicals. Along with being more effective, this method is more environmentally friendly since cleaning doesn't require the use of harsh chemicals or mechanical scrubbing. Tiny cavitation bubbles generated by the ultrasonic system do the removal of impurities from a variety of parts and components, which range robust metal and ceramics to delicate semiconductors.

The three main components of the ultrasonic cleaning system consist of the ultrasonic generator, the transducer, and the cleaning tank.

The cleaning tank holds the cleaning solution as well as parts to be cleaned. It must be heavy and durable enough to withstand the cleaning action of the ultrasonic waves, and big enough to contain the biggest parts to be cleaned.

How doultrasonic cleaners work? The ultrasonic generator produces the electric signal which, in turn, generates the ultrasonic waves via the transducer.

The function of the transducer is to handle the frequency and power produced by the generator to create the ultrasonic waves in the cleaning solution. When the ultrasonic waves travel through the cleaning solution, it creates compression peaks and troughs. The tiny cavitation bubbles form in the troughs where there is low pressure and collapse in the peaks because of high pressure.

When the bubbles collapse, each of them releases a small but powerful jet of liquid, which produce an intense cleaning action on the surfaces of the parts being cleaned. This effectively dislodges any contaminants and any other impurities from the surface of the part being cleaned. The microscopic bubbles can clean even intricate shapes and hard-to-access holes and crevices. Result is fast and thorough cleaning.
