Sequential temperature phased enhanced anaerobic digestion using bioaugmentation microbes to enhance biomethane production from alkali pretreated late cut grass and late cut grass silage
… proposed which combined alkali pre-treatment, temperature phased anaerobic digestion and microbial bioaugmentation to improve biomethane production from lignocellulosic biomass. The proposed concept was known as Sequential Temperature-phased Enhanced Anaerobic Digestion using Microbes (STEADM). …

Comparative Studies of Alternative Anaerobic Digestion Technologies
… technologies include thermophilic, acid/gas phased, and temperature phased digestion. In order to evaluate the relative merits of each, a year long study evaluated the performance of bench scale digestion systems at varying solids retention times (SRT) and organic loading rates (OLR). The …

Anaerobic Digestion: Factors Effecting Odor Generation
… generation. Digested sludge from acid/gas and temperature phased anaerobic digestion systems were analyzed in the lab. The results show that both acid/gas system and temperature phased digestion had a positive impact on odor generation from dewatered biosolids cake. Comparison of sludge from …

Changes in Dewatering Properties Between the Thermophilic and Mesophilic Stages in TPAD Systems
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 of the sludges created by these systems. A laboratory study was conducted …

A Comparative Study of Anaerobic Digestion Processes for Sewage Sludge
… thermophilic anaerobic digestion, acid/gas phased digestion, and temperature phased anaerobic digestion. To obtain design data, a year long study was conducted using bench scale digestion systems operating at different solids retention times (SRT) and organic loading rates (OLR). The …

Effect of Process Intensification Techniques on Biosolids Management
… thermophilic anaerobic digestion, temperature phased anaerobic digestion, and thermal hydrolysis pretreatment. Improved methane production, pathogen reduction, dewatering performance, and odor mitigation were observed with the involvement of these high-temperature processes. …
