Current State of the Practice of Sludge Reduction Technologies

Abstract: The handling and disposal of wastewater sludge is an increasingly costly portion of the operation of a wastewater treatment plant and is developing into an even greater future risk given the trend of decreasing availability and increasing costs of ultimate disposal options. Recently several technologies and process innovations have been proposed to reduce or eliminate the waste activated sludge (WAS) fraction resulting from treatment, or to render it more amenable to anaerobic digestion, a common sludge stabil… Show more

“…These technologies cover both those intended to reduce the generation of wastewater treatment residuals from the liquid process, as well as those designed to pre-condition solids in order to make it more susceptible to subsequent stabilization processes such as anaerobic digestion.In conjunction with the previous papers -"Current State of the Practice of the Sludge Reduction Technologies" (Sandino et al, 2008) and "Underlying Mechanistic Principles and Proposed Modeling Approach for Waste Activated Sludge Reduction Technologies" (Whitlock et al, 2009) -this paper is the third in a series and is intended to present an evaluation methodology framework for solids reduction technologies. In addition, this paper provides an update of the performance data collected from full-scale facilities.…”
