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 ...
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 ...
An Investigation into the Mechanisms of Sludge Reduction Technologies
(Virginia Tech, 2009-03-30)
Anaerobic digestion has been the preferred method for reducing and stabilizing waste sludge from biological wastewater treatment for over a century; however, as sludge volumes and disposal costs increase, there has been a ...
Enhanced Biodegradation in Landfills
(Virginia Tech, 2001-05-14)
The objective of this paper is to evaluate the effectiveness of leachate recirculation and bioreactor landfills at enhancing biodegradation, and to optimize the operation of a bioreactor. Waste Management has been examining ...
Factors Contributing to Trimethylamine Generation from Limed and Polymer Conditioned Sludges
(Virginia Tech, 2007-01-19)
Trimethylamine, (CH3)3N, (TMA), odors are often associated with limed and polymer conditioned sludges. This odor has a fishy smell and can be a nuisance to the community surrounding a wastewater treatment plant or land ...
