Information on dual Biological Nutrient Removal (BNR) systems, based on the experience of plants with sufficient operating history to demonstrate the potential cost savings, treatment effectiveness, and reliability of BNR systems. Volume II details the costs developed for retrofitting eight plants: Arlington, Hopewell, Lower Potomac, Alexandria and Richmond, Virginia; Patapsco and Back River in Baltimore, Maryland; and Blue Plains in the District of Columbia.
