Abstract
A bioreactor designed to produce NO from organic nitrogen and/or reactive nitrogen in waste is coupled to a hardware reactor device in which the NO is consumed in a gas phase chemical reaction, e.g., catalytic decomposition to form oxygen and nitrogen gas. Heat from the exothermic reaction may be used to generate power. The bioreactor may use communities of autotrophic microorganisms such as those capable of nitrifier denitrification, ammonia oxidizing bacteria, and/or ammonia oxidizing archaea. A portion of the NO dissolved in aqueous effluent from the bioreactor may be separated to increase the amount of gas phase NO product. The amount of the gas phase NO in a gas stream may also be concentrated prior to undergoing the chemical reaction. The NO may alternatively be used as an oxidant or co-oxidant in a combustion reaction, e.g., in the combustion of methane.
