Abstract:
1. A method for wastewater treatment and energy production wherein nitrogen is removed from wastewater and converted to nitrous oxide and wherein energy is produced from the nitrous oxide, the method comprising: pumping the wastewater into a bioreactor system, wherein the wastewater comprises ammonia; processing the ammonia in the bioreactor system to produce a nitrous oxide product, with nitrite as an intermediate product, wherein the bioreactor is operated to enhance production of nitrous oxide; feeding the nitrous oxide product of the bioreactor system to a hardware reactor device coupled to the bioreactor system; and chemically reacting the nitrous oxide in gas phase in the hardware reactor device to produce energy obtained from the nitrous oxide product of the bioreactor system, whereby energy is produced from the nitrogen removed from the wastewater.
