| Abstract: | This paper describes laboratory scale results of aerobic and anaerobic biological treatment studies conducted to evaluate the feasibility of treating ground water contaminated with an organic solvent consisting of an equal weight‐mixture of methylethylketone and cyclohexanone. For this purpose, three alternatives were considered, namely a single‐stage anaerobic baffled reactor, an activated sludge system, and an aerated lagoon. The study focused on determining and comparing the treatment efficiency of each of the three treatment processes under similar operating conditions. Aerobic processes proved to be more effective in treating the organically contaminated groundwater. |
