A simulation model was derived to describe the filtration and accumulation of three classes ofantibiotics in slow sand filters. Verification was evaluated by extracting a macrolide antibioticfrom the schmutzdecke of a pilot slow sand filter subjected to a 60 day challenge experiment.The study also examined schmutzdecke sorption behavior and removal efficiencies in the pilotfilter fed 0.2 mg/L of five antibiotics. Aqueous antibiotic concentrations were analyzed byHPLC MS/MS. Schmutzdecke sorption coefficients were comparable to those previously foundfor soils and did not correlate well with estimates derived from octanol/water partitioncoefficients. At the end of a 14-day slow sand filtration period, tylosin was not detected in filtereffluent and trimethoprim was > 99% removed. However, slow sand filtration exhibited < 25%removal of lincomycin and < 4% removal of the sulfonamide class of antibiotics. Slow sandfiltration is regarded as an ineffective treatment method for antibiotics with low filter mediasorption coefficients. Includes 7 references, figures.
