Scale-of-Agitation Approach for Suspensions

Upon determination of design settling velocity, one must choose the scale of agitation required using Table 5 (9), which serves as the suspension products equivalent of Table 3. [Pg.84]

1-2 Agitation levels 1 and 2 are characteristic of applications requiring minimal solids-suspension levels to achieve the process result. Agitators capable of scale levels of 1 will Produce motion of all of the solids of the design settling velocity in the vessel Permit moving fillets of solids on the tank bottom, which are periodically suspended. [Pg.84]

3-5 Agitation levels 3 and 5 characterize most chemical process industries solids-suspension applications and are typically used for dissolving solids. Agitators capable of scale levels of 3 will Suspend all the solids of design settling velocity completely off the vessel bottom Provide slurry uniformity to at least 1 /3 of fluid-batch height Be suitable for slurry draw-off at low exit-nozzle elevations. [Pg.84]
