Ex situ treatment of N-nitrosodimethylamine (NDMA) in groundwater using a fluidized bed reactor

► First fluidized bed reactor evaluated for treatment of NDMA in groundwater. ► System utilizes aerobic cometabolism to achieve low contaminant levels. ► Demonstrated removal efficiency for NDMA of >99.9% at a 30 min HRT. ► First potential biological alternative for UV treatment of NDMA in groundwater.
