The recovery of the biomass in a se

The recovery of the biomass in a sedimenting centrifuge depends on the settling
characteristics of the cells, the residence time of the cell slurry in the centrifuge, and the
settling depth. Settling depth can be kept small through the design of the centrifuge. The
residence time of the slurry in the centrifuge can be controlled by controlling the flow rate.
Heasman et al. (2000) evaluated the extent of cell recovery and the effects of cell viability at
different conditions of centrifugation. Nine different strains of microalgae were assessed
(Heasman et al., 2000). A cell harvest efficiency of >95% was obtained only at 13,000  g.
The harvest efficiency declined to 60% at 6000  g and 40% at 1300  g. Cell viability
depended significantly on the algal species and the method of centrifugation (Heasman et al.,
2000). Information on comparative performance of some centrifugal methods of recovering
microalgal biomass is given in Table 1 (Mohn, 1980). Of the methods shown (Table 1), only
hydrocyclone proved unsatisfactory for the application shown. The other methods were quite
effective for biomass recovery
