Two-Phase Anaerobic Digestion to Reduce the NOx Emission Potential of Biogas
<p>Anaerobic digestion can be used to decrease the mass of organic wastes to be disposed of while producing useful biogas (CH<sub>4</sub> and CO<sub>2</sub>) for heat or power production, but in air basins with strict emissions limits, biogas combustion is difficult to implement due to the high …

Evaluating the potential for improving anaerobic digestion of cellulosic waste via routine bioaugmentation and alkaline pretreatment
In this study, two methods for improving anaerobic digestion processes were investigated. The first method was routine bioaugmentation and the second was alkaline pretreatment. Both of these methods were applied to a two-phase anaerobic digestion process for treating the residuals from sweet corn …

Acid-phase and Two-phase Codigestion of FOG in Municipal Wastewater
Acidogenic codigestion of fats, oils, and greases (FOG) was studied at 37"C using suspended sludge digesters operated as sequencing batch reactors (SBRs). Volatile fatty acid (VFA) production was found to increase with larger FOG loading rates, although this increase was insignificant compared the …

Thermal Hydrolysis of LCFAs and Influence of pH on Acid-phase Codigestion of FOG
Two different sludge pretreatments were investigated in an attempt to improve the management and performance of processes for the co-digestion of biosolids with fats, oils, and grease (FOG). The mechanisms of long chain fatty acids (LCFA) degradation in thermal hydrolysis pretreatment and the …
