Effect of plastics on the lignin results for MSW and the fate of lignin in laboratory solid waste reactors
(Virginia Tech, 2004-10-18)
<p> Cellulose to lignin ratio is one of the widely used indicators of degree of landfill stabilization. This ratio shows the amount of carbohydrate or cellulose consumed by anaerobes compared to relatively inert lignin. ...
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 ...
Anaerobic / Aerobic Digestion for Enhanced Solids and Nitrogen Removal
(Virginia Tech, 2008-12-04)
Anaerobic digestion of wastewater sludge has widely been in application for stabilization of sludge. With the increase in hauling cost and many environmental and health concerns regarding land application of biosolids, ...
Effects of Temperature on Anaerobic Lignin Degradation in Bioreactor Landfills
(Virginia Tech, 2008-12-06)
Bioreactor landfills have become a feasible alternative to the typical â dry tombâ landfill. By recirculating leachate and/or adding additional liquid wastes, bioreactor landfills operate to rapidly degrade and transform ...
Changes in Dewatering Properties Between the Thermophilic and Mesophilic Stages in TPAD Systems
(Virginia Tech, 2000-11-27)
Temperature-phased anaerobic digestion (TPAD) has become increasingly appealing in recent years due to the pathogen destruction capabilities of the system. However, there has also been concern about the dewatering properties ...
