Predicting and Improving the Dewaterability of Waste Activated Sludge Through Moisture Distribution Analysis
The dewatering of waste activated sludge is one of the most costly and least understood operations in wastewater treatment. While much effort has been put into streamlining operation of sludge dewatering equipment to maximize moisture removal, until recently, little attention was paid to the water …

Comparative study of sludge dewatering and thickening characteristics for biological phosphorus removal process and conventional activated sludge process sludges
… conducted to compare batch thickening, vacuum dewatering and centrifugal dewatering characteristics of both sludges. The results obtained indicated both sludges to be highly comparable in all the areas of testing. The results obtained have also been explained in terms of AVI, a measure of …

A study of multi-stage sludge digestion systems
… their solids reduction, odor generation after centrifugal dewatering and indicator organism reduction in comparison to single-stage thermophilic and/or mesophilic anaerobic digestion systems. Pre-aeration of sludge in a thermophilic temperature was also tested followed by single or multi-stage …

Shear Forces, Floc Structure and their Impact on Anaerobic Digestion and Biosolids Stability
… they relate to mesophilic anaerobic digestion, dewatering processes and digestion enhancement by wet sludge disintegration technologies. The working hypothesis of this study is that digestion performance; nuisance odor generation and the degree of digestion enhancement by wet sludge …
