Abstract/Contents

Abstract: The pilot-scale nitritation reactor successfully treated the anaerobic digester centrate from Delta Diablo. When temperature, pH, and dissolved oxygen (DO) were controlled, ammonia was efficiently converted into nitrite. The microbial communities was dominated by widely known and potential ammonia oxidizing bacteria, Nitrosomonas and Xanthomonas. The nitrogen balance carried out on the input and output of the nititritation reactor disclosed evidence of denitrification activity within the reactor, though additional studies are needed to confirm nitrogen removal end product, N2 or N2O. Particulate organic matter in the digester centrate affected the downstream nitrosation reactor performance by preventing the decoupling of nitrite reduction and COD consumption. Preventing the transfer of these solids into the nitritation reactor decreased the suspended solids in the reactor effluent, and is expected to be beneficial for the performance of the downstream nitrosation reactor. Operation of the pilot system continues to further understand and perfect the operation of the nitrosation reactor with the goal of increasing overall nitrous oxide production.
