A rose is a rose is a rose.  But pumps, now that’s a different thing.  Pumps, even though they may look physically the same, can vary significantly in their ability to pump liquids under various conditions.  In order to know how a pump will perform in a particular application, one must rely on something called … Continued

Previous blogs have suggested the use of liquid sprays in air as either a primary mechanism or as an enhancement to both cleaning and rinsing operations.  Today’s blog will discuss, briefly, what is important in choosing a spray nozzle or nozzles for a particular application.  In order for spray to be effective, of course, the … Continued

It occurred to me several years ago that when we look at an ultrasonic cleaning tank, we are usually looking in from the top.  I wondered how ultrasonics looked from a “fish eye” view which spawned (get it?) what is now called the ultrasonic fish tank in our Jamestown, NY laboratory.  In upcoming blogs, I … Continued

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 … Continued

Providing the best and most efficient rinse in an aqueous cleaning process requires maintaining the cleanest possible water in the rinse.  In spray rinses, this can be accomplished by using fresh water for the spray.  A spray rinse with fresh water, although effective, is often not practical.  Using a constant supply of fresh water is costly, especially if … Continued

Today’s blog continues the discussion of valves as promised starting with manually operated valves.  There are three basic types of manual valves – the globe valve, the gate valve and the ball valve.  Of course, there are many variations of each but a look at their inner workings will reveal that they all fall into one … Continued

A previous blog Cleaning – Soluble Contaminants – “Solvents” described soluble contaminants as those contaminants that can be dissolved using a solvent or engineered liquid such as a surfactant.  Contaminants that are not soluble are the other distinct classification of contaminants.  Sometimes the line between soluble and insoluble is not well defined since there are … Continued

Reader’s Questions The blog welcomes reader’s questions and comments related to cleaning.  Just forward questions or comments to jfuchs@ctgclean.com.  Provided I know the answer to your question, I will either answer it by email or, if the question is of general interest, I will answer it in the blog.  If I don’t know the answer, I’ll try … Continued

In the blog entitled The Lowdown on Dirt, the three basic classes of contaminants were described.  They are – soluble, particulate and a mixture of soluble and particulate.  There are, of course many hybrids and permutations but for purposes of discussing the ultrasonic effect on cleaning we’ll limit to these three for now.  Later on we can … Continued
