Description: High Performance Anaerobic Digestion
At the heart of biosolids processing improvements is high performance anaerobic digestion (HPAD). Digestion performance improvements result in more treatment capacity per unit volume to convert wastewater residuals to nutrient-rich, low-odor biosolids, more efficient conversion of organics to methane-rich biogas, and to improve overall biosolids quality. Although there are many conventional high...

Description: High Performance Anaerobic Digestion
Hydrolysis is the rate limiting step during anaerobic digestion of complex materials. Hydrolysis describes a group of reactions whereby complex materials are degraded into simpler ones by extracellular reactions catalyzed by enzymes. The simpler compounds formed are small enough to be transferred across a bacterial cell membrane where they can be further processed. Hydrolysis of waste activated...

Description: High Performance Anaerobic Digestion
Thermophilic anaerobic digestion is similar to mesophilic digestion, except the process occurs at higher temperatures, about 122° to 135° F (50° to 57° C). The higher temperatures help to increase the pathogen reduction. Thermophilic microorganisms have more rapid reaction rates than mesophilic microorganisms.

Description: High Performance Anaerobic Digestion
Aerobic digestion could be used as a pretreatment to anaerobic digestion or as a post-treatment after anaerobic digestion. Combining aerobic and anaerobic digestion could result in significant benefits. Those benefits may outweigh the cost of the aeration energy input and the reduction in sludge energy value from oxidation.

Description: High Performance Anaerobic Digestion
As illustrated in this document, the anaerobic digestion process continues to be improved through process modifications and supplemental treatment mechanisms. Many wastewater treatment facilities have prioritized the recovery of resources as the charter of the organization to meet environmental stewardship objectives. Anaerobic digestion continues to be a robust process to convert wastewater...
