A Comparative Study of Anaerobic Digestion Processes for Sewage Sludge
(Virginia Tech, 2006-02-07)
The Blue Plains Wastewater Treatment Plant in Washington, D.C. is in the process of updating its anaerobic digesters, with a completion date set for 2008. This research was undertaken to aid designers at Blue Plains by ...
The Effect of Steady-State Digestion Temperature on the Performance, Stability, and Biosolids Odor Production associated with Thermophilic Anaerobic Digestion
(Virginia Tech, 2006-11-08)
<p> The performance and stability of a thermophilic anaerobic digestion system are inherently dependent on the engineered environment within each reactor. While the selection of operational parameters such as mixing, solids ...
Sequential Anaerobic-Aerobic Digestion: A new process technology for biosolids product quality improvement
(Virginia Tech, 2006-01-30)
Anaerobic digestion is widely used for stabilization of solids in sewage sludges. Recent changes in the priorities and goals of digestion processes are focusing more attention on the efficiency of these processes. Increasing ...
The Effect of Temperature on Lignin Degradation in Municipal Solid Waste
(Virginia Tech, 2006-09-07)
The Effect of Temperature on Lignin Degradation in Municipal Solid Waste Olga Miroshnikova Chair: Dr. John T. Novak, Ph.D (ABSTRACT) Paper and paperboard are the major constituents found in US landfills. Typically paper ...
Effect of Reactor Feeding Pattern on Performance of an Activated Sludge SBR
(Virginia Tech, 2006-09-19)
<p> The possible effects of changes in the feeding pattern on activated sludge properties related to bioflocculation have been analyzed in lab scale sequencing batch reactors (SBR) in order to determine if these changes ...
Developing a Mechanistic Understanding and Optimization of the Cannibal Process: Phase II
(Virginia Tech, 2006-08-29)
The Cannibal system, comprised of an activated sludge process integrated with a side stream anaerobic bioreactor, is capable of reducing excess sludge up to 60% compared to the conventional activated sludge process. The ...
