Abstract: Mass-transfer and pressure-drop packing performance correlations are used together with tower design equations and detailed cost models to compare the effectiveness of cross-flow and counterflow air stripping towers over ...

Abstract: Polyurethane foam (PUF) is widely used in indoor consumer products. Despite strong potential interactions with volatile organic compounds (VOCs), the effect of PUF on indoor concentrations of VOCs has not been examined. ...

Abstract: Statistical analyses of data sets from five case histories indicate that soil–bentonite hydraulic conductivity is distributed log normally. The advection–diffusion equation was used to investigate the impact of log-normal ...

Abstract: The relationships among adsorption-desorption kinetics, equilibrium partitioning, and fixed-column breakthrough curves are elucidated for airborne benzene and vinyl chloride on activated carbon grains and fibers. An ...

Abstract: The oxygen-transfer characteristics of an upflow biological aerated filter filled with angular clay media were determined over a wide range of gas and liquid flow rates. Liquid-side, oxygen-transfer coefficients

Abstract: The City of Atlanta plans to convert a recently acquired urban quarry into Bellwood Quarry Reservoir (BQR), an off-stream supplemental water supply. CE-QUAL-W2, Version 3.5, was used to perform five-year water quality ...

Abstract: A mechanistic oxygen transfer model was developed and applied to a flow-through hollow-fiber membrane-aerated biofilm reactor. Model results are compared to conventional clean water test results as well as performance data ...

Abstract: A process model for soluble Mn

Abstract: We developed an integral plume model to simulate the behavior of bubble plumes generated from line-source geometry in stratified ambient reservoirs by adapting the double-plume integral model developed for point-sources ...
