Effects of anaerobic digestion on the dewaterability of sonicated biosludge

Journal of Environmental Management
Studies on the impact of anaerobic digestion on biosludge dewatering are conflicting and mechanisms are poorly understood, with significant implications to both wastewater costs and environmental impact. To identify the mechanisms that improve dewaterability and to amplify the impacts of anaerobic digestion, biosludge was first sonicated to deteriorate

Effect of Conditioner on Dewaterability of Sewage Sludge

Nigerian Journal of Technology, 2014
A model for dewaterability of conditioned sludge was derived based on data generated after dewaterability experiments using six sand drying beds. In these experiments, Six beds were used, the first bed contain no conditioner and served as control experiment. Ferric Chloride was added to the remaining five beds in the neighborhood of 1%, 2%, 3%, 4%, and
