The purpose of this study was to determine volatile solids (VS) destruction and biogas production from pilot-scale thermophilic anaerobic digestion with ultrafiltration (TADU) utilizing dairy manure as the substrate. Previous studies have established that thermophilic digestion produces larger quantities of methane and inactivates pathogenic microorganisms more completely than mesophilic digestion. No previous reports of membrane ultrafiltration for dairy manure digestion have been published to the author's knowledge. The study also provides information on anaerobic microorganism toxicity of chemicals commonly found on dairy farms and the effects of biomass storage temperature and storage time on biogas production...
