Single‐stage laboratory models, with liquid recycle, were used to examine the attenuation of phenol (2 mmol dm −3 ) in domestic refuse. High hydraulic loading rates (≥37.3 cm 3 h −1 ) maximised phenol attenuation rates although, with lower loading rates (20.9 cm 3 h −1 ), residual substrate concentrations remained low. With successive reservoir supplementations, these patterns were repeated although for each loading rate the maximum phenol concentration attenuated by each column passage increased. A semilogarithmic plot of hydraulic load against filter efficiency approximated to a straight line and thus indicated that further increases in hydraulic loading rates would not facilitate significantly improved total phenol removals.
