Effect of Substrate Characteristics and Process Fluid Percolation on Dry Anaerobic Digestion Processes

Chemical Engineering &Technology, Volume 43, Issue 1, Page 59-67, January 2020., 2020
Dry batch anaerobic digestion trials in pilot scale and oedometer tests under compression were performed to investigate the influence of material structure and percolation on the dry batch digestion process. Material compaction during the digestion process negatively affects substrate permeability.

Dynamics of dewaterability and bacterial populations in activated sludge

Water Science and Technology, 2012
Relationships of bacterial populations and extracellular polymer substances (EPS) to dewaterability of activated sludge were studied on three laboratory-scale activated sludge reactors fed with synthetic wastewater. Dewaterability of activated sludge was evaluated by a novel method developed by the authors, in which small amount of sludge was ...
