Selecting and Designing Combination Filtration for Solid-Liquid Separation
Photo by Maksym Kaharlytskyi on Unsplash Filtration experts, over the years, have discussed combination filtration and debated its definition. In the realm of cartridge filtration, simply defined, a combination filter is one that does at least one other processing job at the same time as filtering a suspension. For example, this could be carbon canister which removes both suspended and dissolved components. In water applications, a combination filter removes bacteria, sediment, chlorine…
Best Practices for Filtration Testing for Solid-Liquid Separation
Photo by Annie Spratt on Unsplash Testing in school has a negative connotation. Students dread tests. Parents bemoan “teaching to the test.” Teachers chafe against the curriculum parameters defined by testing expectations. Yet, the word “testing” should resonate much more positively with process engineers. After all, testing is the key for selecting the most suitable filtration tech for any individual solid-liquid separation task. Although there is only limited theoretical background available,…
Selecting the Right Types of Filtration for Solid-Liquid Separation
Photo by Picturepest on Foter.com / CC BY Filtration selection, if we think back to Sherlock Holmes, means “not jumping to conclusions.” There is no “one size fits all” process solution. Selecting a filtration technology requires a systems approach incorporated with other solids processing such as reactors, dryers, solids handling, etc. You could gain an objective overview by filling out an application data sheet (like the ones I use for new or existing applications) that can help identify…
