The Dewatering of Biological Suspensions in Industrial Centrifuges

  • P. N. Ward
  • M. Hoare


For optimal design and operation of solid-liquid separation processes a knowledge both of the characteristics of the separating machine and of the suspension which affect clarification and dewatering is required. In this paper we examine those characteristics which determine the extent of dewatering achievable and those which control sediment discharge from continuous centrifuges. Suspensions of Methylophilus methylotropus. Fusarium graminearum and borax flocculated Saccharomyces cerevisiae (bakers yeast) debris are studied.
