Sorting Out Filtration – Filter Types and Media Selection for Increased Filter Life

If a filter is doing its job, its life will be limited.  Eventually it will have filtered out and collected enough particles to be severely restricted or totally block liquid flow.  When this happens, the filter or filtration media must be replaced.  A clogged filter will, at minimum, have process consequences as particle accumulations build up …

Sorting Out Filters – The Effect of Particle Characteristics On Media Selection and Filter Life

The useful life of most media filters is determined by the size and quantity of particles they capture.  Each filter has only a limited number of sites to trap particles.  Once a site traps a particle, flow through that site’s passage is either reduced or stops completely.  When a sufficient number of sites are blocked, flow through …

From Rags to Rinses

It will come as no surprise to anyone who is involved with industrial parts cleaning that rinsing is an expensive but important part of the process.  Although it may not reduce your wardrobe to “rags,” proper rinsing can put a sizeable dent in the cleaning budget.  Let’s talk a minute about how to reduce the cost of rinsing. The …

The BIG Four

There are four basic variables that, combined, establish the success or failure of any industrial cleaning process.  The variables are Time, Temperature, Chemistry and Agitation.  Although there may be additional variables – things like fixture design and variations in the process prior to cleaning – which can have major impact and, in fact, make or …

The Ultrasonic Marching Band

When I first started working with ultrasonic cleaning back in the early 1960’s “ultrasonic” meant 20kHz. That’s all there was! Some very early sonic cleaning equipment used by one of the major automotive manufacturers in the prior decade had operated at 10kHz using a motor/generator to develop the driving signal for some very crude transducers …
