“…The bench‐scale biofilter setup was operated using the combined recirculating batch reactor and single‐pass plug flow reactor experimental protocol developed by Terry et al (2019). The source water was split into two batches for the recirculation batch mode and the single‐pass mode.…”

Fluorescence spectroscopy to evaluate the removal of dissolved organic matter (DOM) via biofiltration under varying operational and water quality conditions was investigated in this study. Three feedwaters (lake, river, and wastewater effluent) were examined at three temperatures (6, 22, and 28 °C) and three empty bed contact times (EBCTs; 5, 15, and 30 min) to simulate seasonal and operational variations experienced by utilities. Parallel factor (PARAFAC) analysis was used to characterize the fluorescing DOM and to determine the component removal. Three components were found in the lake and river feedwaters, and four components were found in the wastewater effluent. In natural source waters, protein‐like components were removed most effectively via biofiltration. In the wastewater effluent, a humic‐like component common in nutrient‐rich waters was removed most effectively, and the protein‐like component was removed second most effectively. Increased EBCT and temperature increased the removal efficiency of bulk DOM and the protein‐like components.

“…An EBCT of 15 min was also evaluated using a sampling port in the middle of the filter. The recirculation/single-pass procedure for media acclimation and biofilter operation was used, which simulates field-scale biofilter performance for organic matter removal as described previously (Terry et al, 2019). In this method, a sample is run in a recirculation mode for 5 days; then, the sample is replaced with a duplicate sample and run single pass through the biofilter to assess organic matter removal.…”

“…This method was validated with pilot results with two WWefs and one drinking water source water. A bench-scale hydraulic loading rate of 1 gpm/ft 2 allows a smaller bench-scale filter depth to be used without affecting the scale-up validation (Terry et al, 2019).…”

“…Coagulation was also evaluated as a pretreatment process for removing TOC since lower TOC both decreases DBP formation and extends the run time of GAC adsorbers (Hooper, Summers, Solarik, & Owen, 1996; Zachman & Summers, 2010). The bench‐scale approach taken is well established for drinking water systems, with results verified at full scale—i.e., scalable: coagulation for TOC (Tseng & Edwards, 1999), biofiltration for TOC (Terry et al, 2019), and GAC for TOC (Crittenden et al, 1991) and DBP precursor control (Cummings & Summers, 1994). The focus in this article was on TTHM and HAA5 regulation compliance.…”

The widespread and successful use of coagulation, ozonation, biofiltration, and granular activated carbon (GAC) adsorption for the treatment of impaired drinking water sources makes them attractive as an economical approach for direct potable reuse. This study systematically evaluated these processes for the treatment of four secondary wastewater effluents with the objective of meeting U.S. drinking water disinfection byproduct (DBP) regulations and developing treatment objectives. Total trihalomethane (TTHM) and the sum of five haloacetic acids (HAA5) targets of 60 and 50 μg/L, respectively, were developed under uniform formation conditions and were related to a target total organic carbon (TOC) concentration of 2 mg/L. Ozonation, followed by biofiltration, was effective in decreasing HAA5 formation to below the target levels, but GAC treatment was needed to meet the target TTHM and TOC levels. Optimizing the TOC removal before GAC treatment extended the GAC run times similarily to those found in drinking water treatment. Drinking water–based DBP formation algorithms were very effective in predicting TTHM and HAA5 formation.
