Abstract:	Biological removal of phenol up to 600 ppm and 2,6-dichlorophenol up to 20 ppm was studied in a well aerated fill-and-draw reactor of 41 capacity at 26 C using an activated sludge obtained from the municipal treatment plant in Livingston, N.J. Experimental evaluation of kinetic parameters showed that biodegradation of both phenol and 2,6-DCP followed zero-order kinetics. As expected, the lag time for both compounds was considerably reduced when acclimated sludge was used. However, the metabolism of 2,6-DCP was very slow even for preacclimated sludge, requiring about 36 hours to degrade only 15 ppm.. This was markedly improved by the addition of amino-acids to the feed solution, which reduced the degradation time for 15 PPM 2,6-DCP to about 10 hours. The loss of substrate due to air stripping was negligible for both compounds at room temperature.
