Abstract

Three commercial microbial preparations were tested for their ability to degrade phenol, 2‐chlorophenol, and 2,4‐dichlorophenoxyacetic acid (2,4‐D), in an aerated biological batch reactor at room temperature (∼26°C). A municipal mixed liquor was used as the control. The municipal population performed better than any of the commercial preparations alone. However, there was an improvement in performance (for the phenolic compounds only) when the commercial preparation cultures were added to the municipal mixed liquor in a 1:20 ratio based on MLSS. Nevertheless, such a high rate of addition would be economically prohibitive. Aqueous concentrations of the individual substrates were determined by direct injection into a gas chromatograph. Changes in the microbial populations were observed using standard plating techniques and light microscopy. Copyright © 1986 American Institute of Chemical Engineers
