Laboratory column tests confirmed that the transport characteristics of microorganism activating tetrachloroethylene (PCE) dechlorination were well described by a mobile-immobile two-region model. Biological reaction was identified as first-order kinetics from batch tests where the bacterium strain was mixed with halogenated aliphatic compounds of PCE or TCE (trichloroethylene) as an initial pollutant. PCE dechlorination to dichloroethylene (DCE) via TCE was mathematically described by a Michaelis-Menten equation while the microbial growth rate was not well represented by a Monod function. Thus, a relationship between the microbial growth rate and the concentration of PCE and TCE was newly proposed and its appropriateness was verified through a numerical simulation of PCE dechlorination in a fixed-bed reactor column.
