An economic comparison between air- and oxygen-activated sludge systems shows that for a plant designed to handle 60,000 lb/day of BOD, the oxygen system is $1.9 million less costly than an air system employing low-speed mechanical surface aerators. The factors to consider when evaluating the potential of pure oxygen for industrial wastewater applications are discussed, including organic removal kinetics, equilibrium aeration basin temperature and pH, stripping of volatile organics (e.g., toluene and benzene), control of odors, susceptibility to shock loadings, operating mixed liquor volatile suspended solids levels, sludge production, and sludge settleability.
