The report summarizes a study of several methods for dewatering a water-softening sludge. Beneficial uses of the dewatered sludge are evaluated. Vacuum filtration after gravity thickening was found to be more economical for the area studied, the Village of Park Forest, Illinois, than centrifuging, lagooning or sand bed drying. The study found that in a dry powder or almost dry condition, the sludge has a potential use as a mineral filler in paints, floor coverings, caulking, and bituminous products, and as a soil admixture and/or soil conditioner.
