For a continuous disk-bowl centrifuge (Figure 8.4) with its liquid passing between the outer (R0) and inner (iy radius, the appropriate definition for Q is Eq. (8.53) with the z-direclion defined as the axial dimension.

These concepts are used to analyze separations in the botde centrifuge, the imperforate bowl centrifuge, and the disk centrifuge. Separation by density difference in other types of centrifuges can be analyzed by analogy. 

One variation of the disk-type bowl centrifuge is the nozzle centrifuge, so named because nozzles are arranged on the periphery or on the bottom of the bowl in a...

Cell harvesting can be carried out by centrifugation disk, bowl, tube, or basket centrifuges are the most popular. The sedimentation process is de-... 

Disk stack separators are vertical bowl centrifuges that are characterized by the presence of a nested conical stack of disks. The centrifuges are usually categorized by the method of solid removal from the bowl and include solids-retaining, solids-ejecting, and nozzle-discharge units. The feed enters the bowl at... 

High-speed centrifugals include tubular-bowl and disk-bowl machines, used for both liquid-liquid and litiuid-solid separations. Capacities are particularly difficult to anticipate for application of the types carried out in such machines. Approximate capacities for several materials are... 

High-speed centrifuges are of two types (1) the Sharpies type, which employs a long hollow bowl of small diameter and is rotated at a very high speed, and (2) the DeLaval type, employing a short disk bowl of large diameter. Such equipment is used largely for clarification and for separation of immiscible liquids. 

Most large-scale equipment for liquid-liquid extraction is available for two-phase extraction and usually multistage systems have to be used for obtaining high yields. Ktihni type columns, Podbielniak centrifugal extractors and disk and bowl centrifuges have been used (Kula et al. 1981 Veide et al. 1983 Cunha and Aires-Barros 2002).
