A simulation model was derived to describe the filtration and accumulation of three classes of
antibiotics in slow sand filters. Verification was evaluated by extracting a macrolide antibiotic
from 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 pilot
filter fed 0.2 mg/L of five antibiotics. Aqueous antibiotic concentrations were analyzed by
HPLC MS/MS. Schmutzdecke sorption coefficients were comparable to those previously found
for soils and did not correlate well with estimates derived from octanol/water partition
coefficients. At the end of a 14-day slow sand filtration period, tylosin was not detected in filter
effluent and trimethoprim was > 99% removed. However, slow sand filtration exhibited < 25%
removal of lincomycin and < 4% removal of the sulfonamide class of antibiotics. Slow sand
filtration is regarded as an ineffective treatment method for antibiotics with low filter media
sorption coefficients. Includes 7 references, figures.
