RESUMEN

This paper presents the results of an investigation on the role of blending in sludge polymer conditioning by evaluating the polymer consumption, and measuring the capillary suction time of waste activated sludge samples blended for different time periods. All of the sludge samples, including non-blended control samples, were conditioned by a cationic high molecular weight polymer in desired concentrations. The protein concentrations of the sludge samples increased as a biological confirmation of cell disruption or desorption of some part of biological polymers present in sludge. Blending decreased the critical polymer dosages required to condition the waste activated sludge samples depending on the blending time applied to the samples.
