Effects of ammonia nitrogen of H2 and CH4 production during The objective of this work was to investigate the potential for using hydrogen gas production to predict upsets in anaerobic digesters operating on dairy cattle manure. In an ammonia nitrogen overload experiment, urea was added to the experimental digesters to obtain increased ammonia concentrations (600, 1,500, or 3,000 mg N/l). Kinetics of methane production during anaerobic fermentation Feb 1, 2020 · With increases in poultr...
