This report summarizes data on the treatment of wastewaters from a liquid detergent manufacturing plant by a rotating biological contactor and presents the findings of an analytical effort to determine the presence or absence of metals and organic compounds which were among those listed in the Consent Decree, Train vs NRDC, et al, June 1976. Even under the best operating conditions, the rotating biological contactor performance was essentially equivalent to that of the extended aeration lagoon. All metals except zinc (0.25 mg/l) were below minimum measurable limits. All organic compounds subjected to analysis by gas chromatograph were below minimum detectable limits.
