“…In our previous study with an 11 L anammox reactor using MCL as a biomass carrier, a maximum VNR of 4.17 kg-N/m 3 /day was obtained (Okamoto et al 2009a, b). In the present study, MCP was used as the biomass carrier for anammox sludge in the both reactors as the main carrier and only a small quantity of MCL was used for the support of MCP in the 400 L anammox reactor.…”

“…Our group has investigated the treatment of brewery wastewater containing organic compounds using a plug flow anammox reactor (total volume 11 L) filled with MC as biomass carriers. The maximum VNR obtained with this system was 4.17 kg-N/m 3 /day with a HRT of 42 min and an influent C/N ratio of 0.196 (Okamoto et al 2009a, b). We are now trying to scale up this anammox reactor for aiming practical applications.…”

A plug-flow type anaerobic ammonium oxidation (anammox) reactor was developed using malt ceramics (MC) produced from carbonized spent grains as the biomass carriers for anammox sludge. Partial nitrified effluent of the filtrate from the sludge dehydrator of a brewery company was used as influent to a 20 L anammox reactor using MC. An average volumetric nitrogen removal rate (VNR) of 8.78 kg-N/m3/day was maintained stably for 76 days with 1 h of HRT. In a larger anammox reactor (400 L), an average VNR of 4.84 kg-N/m3/day could be maintained for 86 days during the treatment of low strength synthetic inorganic wastewater. As a result of bacterial community analysis for the 20 L anammox reactor, Asahi BRW1, probably originating from the wastewater collected at Asahi Breweries, was detected as the dominant anammox bacterium. These anammox reactors were characterized by a high NH4-N removal capacity for low strength wastewater with a short hydraulic retention time.
