The results to date, both laboratory and field pilot plant, indicate that the activated biological contactor ABC concept offers several advantages over fluid bed systems in wastewater treatment. Considerable energy savings appear possible due to the lower oxygen uptake rate of the biomass. Although the oxygen uptake rate of the ABF tower bottoms was relatively high About 200 mg1hr., the rate in the aeration basin following the tower wass less than 50 mglhr. All of the reactors Contactors and aeration basin in the laboratory study exhibit uptake rates less than 50 mg1hr.
