The Digestibility of Waste Activated Sludges

Water Environment Research, 2006
Laboratory digestion studies using waste activated sludges (WAS) were conducted to compare the digestion performance between anaerobic and aerobic processes. Nine samples of WAS from seven wastewater treatment plants were collected and batch‐digested under both anaerobic and aerobic conditions for 30 days at 25 °C.

Predicting the Degradability of Waste Activated Sludge

Water Environment Research, 2008
The objective of this study was to identify methods for estimating anaerobic digestibility of waste activated sludge (WAS). The WAS streams were generated in three sequencing batch reactors (SBRs) treating municipal wastewater. The wastewater and WAS properties were initially determined through simulation of SBR operation with BioWin (EnviroSim ...

Oxidation and ozonation of waste activated sludge

Journal of Environmental Science and Health, Part A, 2008
In this bench-scale study, the treatment of waste activated sludge (WAS) was evaluated using aerobic digestion and ozonation. Two, 2-L batch digesters, one aerated and the other one ozonated, were operated for 30 days in each phase of the study. The aerated digester simulated the aerobic digestion process and served as control to the ozonated digester.

EFFECTS OF SLUDGE PROPERTIES ON THE THICKENING AND DEWATERING OF WASTE ACTIVATED SLUDGE

Proceedings of the Water Environment Federation, 2007
The thickening and dewatering of waste activated sludge, from a pilot‐scale submerged membrane bioreactor and two bench‐scale, complete‐mix activated sludge reactors (high‐shear and low‐shear aeration) treating the same municipal primary effluent, were investigated.

Closed cycle of recycling of waste activated sludge

Waste Management, 2018
The recycling of waste activated sludge (WAS) formed in the process of biological purification of sewage is an urgent ecological problem. In the present work, two ways of recycling of WAS containing from 8 to 30% free water, namely, the synthesis of a carbon-containing component and synthesis of porous building ceramics (bricks) with the use of WAS and

The analysis of volatile siloxanes in waste activated sludge

Talanta, 2007
The increasing presence of siloxanes in waste activated sludge (WAS) considerably hampers the energy use of the biogas obtained during the anaerobic digestion of the sludge when concentrations exceed critical limits. To prevent the occurrence of unacceptable operating conditions, it is hence necessary to have a reliable analysis method for determining ...
