FULL-SCALE FIXED-BED BIOLOGICAL PERCHLORATE DESTRUCTION DEMONSTRATION: CONSTRUCTION OF A FIXED-BED BIOREACTOR WELLHEAD TREATMENT SYSTEM
Brown, J.
ESTCP Project ER-201169, 94 pp, 2019
The efficacy of a 2-stage, fixed-bed biological treatment (FXB) system to address perchlorate-contaminated groundwater was evaluated at a facility in Rialto, Calif., alongside a fluidized bed bioreactor to enable comparison of the performance of the two biological treatment systems. Operation of the full-scale FXB system began on November 9, 2017, demonstrating successful removal of perchlorate (plus complete and consistent removal of 1.85 µg/L of TCE) and producing water that met all performance goals and water quality objectives. This report presents key findings and lessons learned from the project, including optimal chemical dose, backwash frequency, and plant hydraulics to be incorporated in future designs and operations. https://www.serdp-estcp.org/content/download/49129/468610/file/ER-201169%20Final%20Report.pdf
