Long term environmental fate of polychlorinated dibenzo-p-dioxins (PCDD) and polychlorinated dibenzofurans (PCDF) were studied using the fugacity-based dynamic multimedia environmental fate model. New formulation about soil wind erosion into air was included into the model. Effect of process assumption, sensitivity analysis for parameters, and tentative(More)
Environmental profile transformation and fate of polychlorinated dibenzo-p-dioxins (PCDD) and polychlorinated dibenzofurans (PCDF) were studied using the fugacity-based multimedia environmental fate model. Mass fluxes between compartments were estimated by the steady-state modeling. From the model estimates, major mass fluxes coming from emission source(More)
This work aimed to study the use of consolidated bioprocess (CBP) yeast expressing five cellulase genes (BGL, XYNII, EGII, CBHI and CBHII) for ethanol production from ionic liquid-pretreated bagasse and Laubholz unbleached Kraft pulp (LUKP). A proposed screening method shows that the optimal cellulase ratio varies for each biomass substrate, and thus it is(More)
Biological process-free ("Bio-free") treatment of swine wastewater (pH 8.5 or above) for the removal of nitrogen and phosphorus was examined. In this study centrifugal separation of solids and liquids was followed by iron electrolysis, which enables removal of nitrogen and phosphorus when iron is set as the cathode and anode, respectively. The manner in(More)
