This study develops, evaluates, and optimizes the potential of a novel "counter-diffusional?membrane biofilm reactor to biologically treat and remove trichloroethylene (TCE) from contaminatedsoil and groundwater caused by industrial activities (industrial solvent). The objectives of the researchare to investigate and evaluate design and operational factors reflecting the sustainability anddegradation rates of TCE transformation in a counter-diffusional membrane-attached methanotrophicbiofilm reactor systemAs a first step attaining this objective, an overall mass transfer coeficient of the bioreactor wasdeveloped a 23 laboratory experimental design have already conducted, and the development of amathematical model and computer simulation describing the concentration profile of substrates and TCEwithin the biofilm has been introducedA maximum sustainable TCE removal j7|o: of 205 Elmo!/m7/day was successfully attained when theCH,ยข utilization rate was 11.67 mmoles/m2/hr, the TCE loading rate was approximately 400 mol/m2/day.Normal probability plot and pareto chart indicated that methane partial pressure (P) and hydraulicReynolds 's numbers (Re) have important and significant positive effects on the TCE degradation rates.The average percentage of TCE removal eficiency falls between 78.6 and 94. 7%. |
