Beyond the Cleaning Lab Test Results

Process testing in a cleaning laboratory is a typical and useful step in the development of an industrial cleaning process.  In most cases, test cleaning is performed in laboratories maintained by the suppliers of cleaning equipment and/or cleaning chemistries.  The goal of lab testing, of course, is to simulate a cleaning process to determine its effectiveness …

Common Misconceptions About Oil Removal Using Oil Coalescers

Preceding blogs have described oil removal techniques for industrial cleaning in some detail.  It would be nice if this was always a simple consideration – but it is not! The case for using an oil coalescer is pretty clear cut as long as the cleaning chemistry is truly a “splitter” AND, THE OIL IS NOT WATER SOLUBLE.  …

What Makes A Cleaning Requirement Challenging?

The preceeding blog discussed what is probably the “granddaddy” of all cleaning challenges – burned-on carbon.  But, as those of us who have been in the cleaning business since Noah launched the ark know, there are a bunch of other cleaning challenges that defy modern technology.  In general, these challenges fall into a small group …

Flammability – More Things You Should Know – LFL and UFL

Although, fortunately, we seldom encounter flammability issues in cleaning, it’s a good idea to be familiar with some of the terms like Upper and Lower Flammability and Explosive Limits for the sake of safety. In the preceding blog, it was explained that three things were needed to produce a fire – Fuel, Oxidizer, and a …

Applications Notes – Ultrasonic Filter Cleaning

Filters used to filter air, water and chemicals in industrial processes can cost thousands of dollars and more.  Some filters are intended to be renewable by cleaning.  Other filters, even some considered “disposable,” can be recovered for re-use using ultrasonic cleaning techniques. A filter, as we discussed in earlier blogs (search “filter”) is a device …

Ultrasonic Cleaning – More About Baskets and Fixtures

This blog is in response to recently received reader questions regarding the best designs for baskets and fixtures used in ultrasonic cleaning applications.  The blog Reader Questions – Baskets for Ultrasonic Cleaning addressed previous questions.  Today’s question concerns the use of metallic fasteners in the construction of baskets and fixtures to hold parts for ultrasonic cleaning. The …

Water – De-Ionoized – Right and Wrong

This blog explores some common mistakes made in the application of de-ionization hardware.  Although a properly engineered and installed de-ionization system will prevent these potential mistakes at the start, post-installation modifications by those less knowledgeable about de-ionizing technology don’t always respect good design practices. Temperature Limits – In general, de-ionization systems are not intended to …
