Americans generate somewhere between 300 to 400 million tons of garbage every year. Out of environmental concerns for how burning affects air quality, most solid waste ends up in landfills. Chances are you live within 10-20 miles of a landfill, and if your community is anything like most in the United States, your municipal government is running into a real problem: the landfills are filling up, and better solutions are needed.

In the late 1990s, the children’s TV show, Bob the Builder famously asked: “Can we fix it?” Maybe you’re asking a similar question, but about ultrasonic cleaners: “Can an ultrasonic cleaner clean it?”
In most cases, the answer is “yes it can.” [Read more…]
In the world of ultrasonic cleaning, the word used most often is “cavitation”. Generally speaking, most people simply know this to be, “the bubbles in an ultrasonic tank that clean the contaminants off a dirty industrial part”.
Well how are cavitation bubbles formed? A transducer produces sound waves that multiply liquid. The liquid is subjected to negative and positive pressure points and form shock waves. One of the results of these shock waves are implosions, which are used to assist ultrasonic cleaning.
There are two simple ways to properly test your Omegasonics machine to make sure it is cavitating properly. These tests are also unique and interesting ways to show clients or friends what ultrasonic cleaning really does!
1) Glass Slide Test
Take the frosted side of a glass slide and wet it with water. Draw an X with a pencil from one corner to another. Now, gently place the glass into a fresh batch of cleaning solution and turn your Omegasonics machine on. If your machine is cavitating properly, the “X” will disappear immediately and everything will be gone in 10 seconds.
2) The Foil Test
Take a sheet sized piece of regular aluminum foil (not heavy duty or freezer duty) and.place the foil in a vertical position into the ultrasonic tank.
Hold it steady for 60 seconds, remove the foil and gently shake off any water droplets. The foil surfaces will have holes shot throughout the sheet and will be evenly covered with a tiny pebbling effect (cavitation bubbles imploding on the foil’s surface). It’s a cool way to show how sound waves can clean so well.
You will notice a foil test with an Omegasonic machine has a nice density of pinholes (cavitation) with a very uniform and even distribution of ultrasonic cleaning power.
