This slide presentation outlines biological drinking water treatment, pilot-scale demonstration casestudies, andconsiderations for full-scaleimplementation. Topics outlined under biological drinking water treatment include: general treatment process summary; microbially-mediated redox reactions; fixed-bed bioreactor; biofilms; and, conceptual biofilm model. Three pilot-scale demonstration case studies are outlined and include: treatment of perchlorate contaminated groundwater from the Saugus Aquifer at the Castaic Lake Water Agency; combined arsenic/perchlorateremoval and residuals treatmentby electrodialysis reversal +BIOBROx at the Magna Water District, Utah; and, substrate-enhanced biofiltration in Manatee County, Florida. The third part of the presentation outlines considerations for full-scale implementation and includes: equipment; operating parameters; operating strategies; and, safety factors and reliability features. Includes figures.
