Any discussion of water quality and the purification of water will eventually gravitate to a discussion of ions. Adding ions and/or removing ions using what is called an ion exchange process is a big and essential part of most water treatment. Let’s take a few minutes to understand basically what these important things called ions are …
Just about everyone is familiar with the term “hard” water but few know what it really means. In this blog I’ll try to explain what “hard” water is and why we prefer water that is “soft.” In the blog It’s Time To Talk About Water – Again, items 2 and 3 in the list of water contaminants …
Almost every cleaning system incorporates at least one pump. Understanding how that pump works and how to treat it with the gentle, loving care it deserves is critical to the successful operation and maintenance of a cleaning system. Pumps are, in general, devices which impart added pressure to a flow of liquid. Although there are a number of different …
I thought that title might get your attention! Actually, this blog is about “stuff” including, literally, “rocks” that can be found in many water supplies both municipal and otherwise. It is important to differentiate between things that are dissolved in water that leave “rocks” behind when the water evaporates and things that are in the …
Although the importance of “degassing” liquids prior to their use in an ultrasonic cleaning or rinsing process is pretty much common knowledge, the source of the gas and details of how to remove it are less well known. This blog is the beginning of a series which will describe in some detail where that gas comes …
Many ultrasonic generators are configured to operate at one power level – full on. There are occasions, however, when controlling the ultrasonic power is critical to a successful ultrasonic cleaning process. This is especially true when cleaning parts made of relatively soft materials including brass, copper and, in some cases, even aluminum. Other cases requiring …
In the blogs about transducers I made a point of telling readers that an ultrasonic transducer must be driven at its resonant frequency to achieve optimum performance. What I didn’t address, however, was the fact that the resonant characteristics of a transducer can be varied by its design. Not only the resonant frequency but the “sharpness” or “Q” …
In an ultrasonic cleaning system, the device that provides the electrical energy to power the ultrasonic transducers is known as the ultrasonic “generator.” Basically, the ultrasonic generator converts electrical energy received from the power line into electrical energy with the proper frequency, voltage and amperage to power or “drive” the ultrasonic transducers. In most cases, …
Most cleaning today is based on aqueous (water based) technology. Wash, rinse and dry cleaning has become the norm. But, for those of you who are new to the cleaning industry and don’t know, Chlorinated and Fluorinated solvents were the cleaning “benchmark” for many years. Virtually every manufacturing facility cleaned something using a vapor degreaser with …
Today’s ultrasonic transducers utilize either the piezoelectric or magnetostrictive effect of materials to produce ultrasonic waves in liquids. This blog will concentrate on the magnetostrictive ultrasonic transducer. Magnetostrictive Transducers – Magnetostrictive ultrasonic transducers utilize the principle of magnetostriction exhibited by “ferromagnetic” materials which include iron, nickel and cobalt as well as many alloys of these …
