Modeling Transport And Biodegradation Of PCE In Sandy Soil

Transport of microorganism activating tetrachloroethy lene (PCE) dechlorination was well described by mobile-immobile two-region model from laboratory column tests. Biological reaction was identified as first-order kinetics fi-om batch tests where the bacterium strain was mixed with halogenated aliphatic compounds of PCE or TCE (trichloroethylene) as initial pollutant. PCE dechlororenation to dichloroethylene (DCE) via TCE was mathematically expressed as Michaelis-Menten equation while microbial growth rate did not show good performance due to Monod function .
