For design purposes, three levels of solids suspension are defined: 1. On-bottom movement 2. Off-bottom suspension 3. Practical, uniform suspension On-bottom movement is not normally used for design purposes; off-bottom suspension—the most commonly used design crite- rion—was originally defined by Zwietering (1958) as the impeller speed (Njs), which suspends solids with no particles resting on the vessel bottom for > 1–2s. |
