The design of rotating biological contactor (RBC) systems for nitrifying municipal wastewater or leachates from hazardous waste landfills is based on empirical curves developed by various manufacturers of RBCs. The applicability of zero-order nitrification kinetics to the rate of oxidation or disappearance of ammonia nitrogen (NH3-N) in RBCs has been previously established. The purpose of this paper is to illustrate the use of zero-order kinetics to incorporate nitrification in the design of an RBC treatment facility, illustrate the effect of temperature on the number of RBC units required, and define the rationale behind the steps employed in the design process. A step-by-step design procedure is presented as an example design problem.
