Rheological measurements provide fundamental information on the physical properties of activated sludge. Such properties influence the behavior of activated sludge in wastewater and sludge management processes. Measurement of rheological properties of activated sludge is complicated by the large size of aggregate particles in the suspension and by their settleability. Use of a fabricated coaxial cylinder rotational viscometer and a commercial coaxial cylinder rotational viscometer to measure basic rheological properties of activated sludge is described in this paper. The choice of instruments and the range of shear rates used influences the results obtained. (Author abstract. )
