Abstract : This study demonstrated the treatment of low and high concentration levels of perchlorate laden groundwater to potable-like water using a biological fluidized bed reactor (FBR) treatment train. The objectives were to demonstrate: (1) complete treatment of nitrate and perchlorate to drinking water standards using a only a biological inoculum from the incoming groundwater and (2) the use of a downstream post aeration vessel, multimedia filter, and LGAC to produce a potable-like effluent water stream. For the study, the objectives were successfully demonstrated. Using only the groundwater, the FBR system was biologically seeded and demonstrated effective removal of the nitrate and perchlorate at the design loading conditions to meet the State of California Public Health Goal standards. In addition, the downstream equipment operated to produce an effluent water of potable quality, meeting all State of California primary and secondary MCL requirements established under Title 22.
