1. An apparatus for converting biomass, the apparatus comprising:
a) an acidification reactor of a mixed fluid type reactor for microbial hydrolysis and acidification of biomass, comprising an intake comprising an inlet for receiving biomass, and a discharge end comprising an outlet for discharging acidified biomass, wherein the acidification reactor is operated at a temperature of from 45° C. to 70° C. and a pH of from 3 to 4.5; b) a methane synthesis reactor of a solid bed reactor type for anaerobic microbial conversion of the acidified biomass into methane, comprising an intake for receiving the acidified biomass from the acidification reactor and a discharge end comprising three outlets for discharging processed sludge biomass, methane comprising gaseous effluent and acidified liquid biomass, wherein the methane synthesis reactor is operated at a temperature of from 20° C. to 60° C., a pH of from 6.5 to 8, and a redox potential of from −150 mV to 450 mV; c) an additional methane synthesis reactor of a mixed fluid type reactor for the anaerobic microbial conversion of the acidified liquid biomass into methane comprising an intake comprising an inlet for receiving the acidified liquid biomass from the methane synthesis reactor and a discharge end comprising two outlets for discharging processed liquid biomass and the methane comprising gaseous effluent, wherein the additional methane synthesis reactor is operated at a temperature of from 20° C. to 60° C., a pH of from 6.5 to 8, and a redox potential of from −150 mV to −450 mV; and d) a nitrification reactor for aerobic microbial conversion of NH4+ into NO3−, comprising an intake comprising an inlet for receiving the processed liquid biomass from the additional methane synthesis reactor, and a discharge end comprising an outlet for discharging nitrified processed liquid biomass, wherein the nitrification reactor is operated at a temperature of from 5° C. to 37° C., a pH of from 6.5 to 7.5 and a redox potential of more than 50 mV. |
