Questioning Particle Generation Due to Cavitation Erosion as a Source of Contamination

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 surface being cleaned and that liquid motion (streaming) carries the particles away once they have been dislodged.  However, it is also well known that ultrasonic cavitation …

Exhausting 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 otherwise raise the temperature in the cleaning area Remove humidity that would otherwise raise the humidity in the cleaning area Remove toxic fumes that might otherwise be dangerous …

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 tension arise.  In cleaning chemistry, for example, we are always looking for lower surface tension to promote penetration of small surface features …

Surface 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 of this out).  In doing the normal background research, however, I started to see contradictions …

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. Most leaks occur where one piece of plumbing connects with another.  A pipe to a valve, unions, connections to pumps and filters and …
