Abstract: Orlando, Florida is now constructing a new advanced waste treatment plant that removes both nitrogen and phosphorus to a high level. The plant is notable because it is the largest rotating biological contactor (RBC) plant to be built in the U.S. — 24 mgd (most RBC plants are between 1 and 10 mgd). It is also the first RBC plant to completely remove nitrogen (i.e., nitrification + denitrification). In the past six years, the rotating biological contactor process has grown rapidly, going from no plants to over 300 already in operation. An RBC plant uses far less energy than a conventional activated sludge plant. And cheaper energy costs have been the major factor behind RBC's growth. Other growth factors include EPA's emphasis on doing life-cycle cost analyses; and growing requirements for nitrification, which the RBC process does readily.
