Abstract Conventional and alternative flow configurations of rotating biological contractors were compared for soluble organic carbon and ammonia-nitrogen removal. Each treatment train contained eight shafts with a cumulative surface area of 800,000 ft sq. The hydraulic bay used the conventional flow configuration with eight single-shaft stages. The organic bay was modified so that the first stage contained four shafts, the second stage contained two shafts, and the third and fourth stages each contained one shaft. The flowrate was varied from 50% to 200% of design flow, with the two bays operating in parallel below 150% of design flow. After treatment by 400,000 ft sq of surface area, the hydraulic bay had soluble cBOD concentrations that were lower than those in the organic bay in the parallel flow experiments.
