Abstract:
Processes are disclosed for the microbial nitritation of ammonia that attenuate the production of at least one of nitrate anion and nitrous oxide. The processes use an ME biocatalyst having a highly porous, hydrophilic polymeric structure with ammonia-oxidizing microorganisms substantially irreversibly retained therein. The processes are particularly useful for integration with anammox processes.

Claim (Index 13):
A continuous process for the nitritation of ammonia in an aqueous medium using ammonia-oxidizing nitrifier microorganism comprising:\n a. continuously feeding said aqueous medium to at least one bioreaction zone containing biocatalyst wherein said aqueous medium is contacted under aerobic conditions at a temperature of from about 0\u00b0 C. to 50\u00b0 C. and at a pH greater than 7 with said biocatalyst to provide a treated aqueous medium containing nitrite anion, said biocatalyst comprising:\n i. a solid structure of hydrated hydrophilic polymer defining an interior structure having a plurality of interconnected major cavities having a smallest dimension of between 5 and 100 microns and a Hydration Expansion Volume (HEV), which is calculated in volume percent, of 1000 or more, and \n ii. a population of microorganism substantially irreversible retained in the interior structure, said population of microorganism being in a concentration of about 60 grams or more per liter based upon the volume defined by the exterior of the solid structure when fully hydrated, wherein the microorganisms maintain their population as substantially stable; and \n b. continuously withdrawing from said at least one bioreaction zone said treated aqueous medium, wherein the combination of pH of said aqueous medium is sufficiently above 7 and duration of contact of said aqueous medium in the at least one bioreaction zone containing biocatalyst is sufficiently brief that that the treated aqueous medium contains greater than about 1 milligram of ammonium cation per liter, to provide a treated aqueous medium having a mole ratio of nitrate anion to nitrite anion less than about 1:8.
