Abstract:
A technique for wastewater treatment involves ensuring that all paths for wastewater must pass through at least one porous microbial support to go from the inlet to the outlet, and allowing a biofilm to grow on the porous microbial support under microaerobic conditions (concentration of oxygen between 0.05 and 0.35 mg/L). The biofilm formed comprises a population of anaerobic microbes for digesting organics in the wastewater including methanogenic microbes, and an aerobic methanotrophic and heterotrophic population that catabolizes methane from the methanogenic microbes, and oxygen from the injector, to produce heat. The support may be an electrode, and the technique is applied in a microbial electrolysis cell, with substantial COD removal rates.

Claim (Index 1):
A method for wastewater treatment comprising:\n placing at least one porous microbial support within a reactor such that the supplied wastewater must pass through the at least one porous microbial support to exit; supplying a wastewater at an inlet of the reactor; supplying oxygen into the reactor, so that the concentration of oxygen is between 0.05 and 0.35 mg/L averaged over the tank volume in an operating interval of 12 min. or less, to permit a consortium of microbes to define a biofilm on the at least one porous microbial support, the biofilm comprising anaerobic methanogenic microbes covered, and protected from oxygen, by a layer of aerobic methanotrophs and heterotrophs; wherein the methanotrophs catabolize methane produced by the methanogenic microbes and oxygen from the supply, to provide heat within the film for the growth of the film and decomposition of organics within the wastewater.
