Disk-Stack Centrifuge Cell-Culture Clarification

Therein, V b signifies the centrifuge-bowl volume. Based on those calculations, the cell damage index can be expressed by a power law as a function of both dissipated power and bowl residence time (Equation 18). We identified the constants in Equation 18 as k = 0.16, α = 0.98, and β = 1.4 based on the CDI and model-fitting method described ...

CENTRIFUGES

Sedimenting centrifuges remove solids from liquids by causing the particles to migrate radially towards the walls of the centrifuge bowl. The basic types of centrifuges in this category are: a) the high speed, tubular bowl type with manual discharge of solids; b) the skimmer pipe/knife discharge types; c) the disc-type centrifuge; and d) the continuous scroll discharge …

Optimization of industrial-scale centrifugal separation of biological

About the disc stack centrifuges, as the rotating centrifuge bowl is completely symmetric, a 45° sector was considered for meshing. The number of discs was set up to 18 for DSC2 and 36 for DSC1. Meshing was done using unstructured tetrahedral cells. The mesh quality was analyzed based on the skewness and aspect ratio criteria.

To overcome this issue, a plain disk is welded at the conveyor hub between the feed zone and the conical part (Records and Sutherland, 2001). The cake baffle disk has a smaller diameter than the centrifuge bowl and creates a gap which serves for the pre-compaction of the material. This ensures a highly compacted non-flowable sediment during
