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 …
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 …
One important step on the path to solving any problem is understanding the enemy and the risk it poses. The enemy, in this case particles, come in a wide variety of sizes and shapes. A particle’s effect on the ultimate use of the part it contaminates may depend not only on its size, but on …
Many topics can’t be covered in a single, one page blog entry. For this reason, some of the more involved topics will be discussed in several sequential blogs with a common theme. This is the start of one such series about filters and filtration. In parts cleaning, filtration is applied to liquids used to clean …
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 …
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 …
Have a Happy and SAFE Fourth of July!
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 …
Having a means to evaluate and monitor the cleanliness of parts after cleaning is essential to assure the success and consistency of any cleaning process. Selecting and properly applying the appropriate cleanliness test for a particular application is a task that should not be taken lightly. A cleaning test should be able to quantify the …
The vast majority of industrial cleaning processes today use water-based chemistry for cleaning and the cleanest water possible for rinsing. Most water comes from wells or reservoirs and arrives via a municipal utility which may filter it and add chemicals to kill and prevent the growth of bacteria and/or provide certain health benefits. Other than …
