Several bioreactor configurations have been employed in experimental studies addressing the aerobic cometabolism of chlorinated solvents such as trichloroethene (TCE). Application of these reactors is primarily for the treatment of contaminated ground water extracted during remediation. Basically, these reactors can be classified as either suspended or biofilm type and as either continuous or intermittent operation. This paper will examine how the reactor configuration impacts the predicted performance for different applications, as measured by degree of TCE removal and TCE destruction rate per unit volume of reactor. Design methodology based on underlying kinetic principals of cometabolism, such as enzyme competition and endogenous decay, will be developed. The impact of microorganism type, substrates, growth requirements and media type on reactor performance will be addressed.
