Venting
The environment in the area of an industrial cleaning system is often not a “healthy” one for personnel or equipment. Caustic and acidic cleaning chemistries rise as mist above cleaning processes...
View ArticleUltrasonic Drying – Not Yet but Possible???
There has been a lot of buzz lately on the internet regarding work at the Oak Ridge National Laboratory to develop a dryer that uses ultrasonics instead of heat to dry things. The major thrust seems...

Reliability of Plumbing Fittings – Threaded vs. Compression
Wherever there are liquids there are leaks – it’s inevitable. Leaks, of course cost money in downtime and repair of industrial cleaning systems. So, you ask, what is the best defense against leaks....
View ArticleSurface Tension and/or Wettability
A few days ago, I sat down to write what I thought would be a simple explanation of surface tension and how it is measured in the laboratory (a blog which will be published shortly if I can figure all...

How do you measure surface tension?
In the world of industrial cleaning technology we talk about surface tension a lot! So much so, in fact, that it is hard to enter into any discussion of cleaning without having the subject of surface...
View ArticleExhausting Gasses Produced by the Cleaning Process
In many industrial cleaning processes it is necessary to exhaust emissions that unavoidably result from the cleaning process. The reasons for exhaust can take on a large range - Remove heat that would...

Heat – Definitions and Concepts
Temperature has been identified as one of the important variables in cleaning – arguably the most important. So I thought it might be worth some time to develop a little understanding of heat – –...

Heat Conductivity and Convection
Heat conductivity is a measure of the ability of a material to transfer heat within itself. For example, if you heat one end of a short piece of copper wire, the heat is quickly distributed throughout...
View ArticleConductivity Calculations
Previous blogs have talked about heat conductivity in very general terms to produce a foundation for this somewhat more technical view for those of you who like formulas and numbers. Conductive heat...

Questioning Particle Generation Due to Cavitation Erosion as a Source of...
Ultrasonic cleaning is widely used for removing particles from surfaces. It is generally agreed that the high energy of implosions of cavitation bubbles break the bonds holding particles to the...
