Abstract

The use of rheological measurements is examined for the prediction of optimum operating parameters for solid-liquid separation in a scroll decanter centrifuge. The relationship of the complex shear modulus ('total shear stiffness') and loss angle (relative contribution of viscous and elastic components) is examined in relation to the extent of dewatering obtainable in the solids discharge. The system chosen for study is a homogenate of Saccharomyces cerevisiae (baker's yeast), selectively flocculated with the cationic polyelectrolyte polyethylenimine (PEI).
