These researchers investigated, at bench scale, the dewatering performance of drinking-water treatment plant sludges under varying shear conditions and the effect of conditioning with polymers. It was found that unconditioned alum sludges fracture during mixing and are more sensitive to the intensity of shear than to the mixing time. Polymers reduce this tendency to deteriorate, with the dosage required for the best dewatering depending on both the mixing time and the intensity of shear. Lime-softening sludges do not deteriorate when subjected to shear. Includes 12 references, table, figures.
