Aqueous ammonia soaking (AAS) effect on methane yield: verification in continuously fed digesters.
AAS resulted in 98% increase of the methane yield of swine manure fibers in continuously fed digesters.
ADM1 was successfully adapted to simulating anaerobic digestion of swine manure.
Modification of hydrolysis kinetics was necessary for an adequate simulation of the digestion of AAS-treated fibers.
