Drum scrubber design and selection,the design and selection of drum scrubbers is an inexact science at best with little published data on selection criteria or calculation procedure. To date most scrubbers have been selected on simple criteria such as global slurry residence time rather than more rigorous criteria such as solids residence time or degree of attrition.
