Anaerobic bio-transformation of chlorinated organics such as chloroform can be modeled using a second-order rate expression. the process is typically called co-metabolism, and it is typically assumed that the concentration of bacterial remains constant. if the second-order rate coefficient is 0.005 l/mg-d and the concentration of bacteria is 100 mg/l, how many days will it take for an initial concentration of chloroform to be reduced to 1% (i. e. 99% reduction).
