The fate and effect of monensin during anaerobic digestion of dairy manure under mesophilic conditions
There is growing concern about residual antibiotics and feed additives in the manure of treated animals because of the effects of these residues in the environment. Monensin is the most widely used ionophore coccidiostat in the U.S. The objective of this study was to determine the fate and effect of monensin during the anaerobic digestion of dairy manure. Duplicate plug flow field-scale digeste...
متن کاملEffect of Cefazolin and Waste milk on Multi-drug Resistant Bacterial Reduction during Anaerobic Co-digestion of Dairy Manure and Waste Milk
Anaerobic digestion is one of the major biological waste treatment processes in use today. Waste milk from mastitic cows treated with cefazolin is considered a good candidate as a co-substrate in anaerobic digestion. The objective of this study was to determine the effect of cefazolin (10 mg L) and waste milk on reduction of multi-drug resistant bacteria (MDRB) resistant to three groups of anti...
متن کاملAnaerobic co-digestion of forage radish and dairy manure in complete mix digesters.
Pilot-scale digesters (850 L) were used to quantify CH4 and H2S production when using forage radish cover crops as a co-digestion feedstock in dairy manure-based digesters. During two trials, triplicate mixed digesters were operated in batch mode with manure-only or radish+manure (27% and 13% radish by wet weight in Trial 1 and 2, respectively). Co-digestion increased CH4 production by 11% and ...
متن کاملModeling of ammonia speciation in anaerobic digesters.
Anaerobic digestion of high-nitrogen wastes such as animal manure can be inhibited by high concentrations of un-ionized ammonia, NH(3) (aq). Understanding the toxicity of NH(3) (aq) to anaerobic digestion requires a method for determining its concentration. Previous work on ammonia toxicity in anaerobic digesters has utilized a simple equilibrium calculation for estimating NH(3) (aq) concentrat...
متن کاملMethane Production from a Pilot-Scale Fixed-Film Anaerobic Digester and Plug-Flow Digester Loaded with High-Solids Dairy Manure
Three pilot-scale anaerobic digesters (two of a unique fixed-film design, of which one was fed micronutrients, one not, and an identically sized plug-flow digester, which served as the control) were monitored for methane production as a comparative indication of performance. All of these pilot-scale digesters were loaded daily with high-solids dairy manure, passed through a 1.5" x 3" mesh scree...
