Mass Transfer And Benzene Removal From Air Using Latex Rubber Tubing And A Hollow-Fiber Membrane Module, Mark W. Fitch, Jeffrey Neeman, Ellen England

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

A Dense-Phase Latex Rubber Tube and a Polyporous Propylene Hollow-Fiber Membrane Module (HFMM) Were Investigated for Control of Benzene-Contaminated Gas Streams. the Abiotic Mass Flux Observed through the Latex Tube Was 3.9-13 Mg/(Min·m2) for 150 Ppm of Benzene at Various Gas and Liquid Flow Rates, While a 100-Fold Lower Mass Flux Was Observed in the HFMM. after Seeding with an Aromatic-Degrading Culture Enriched from Activated Sludge, the Observed Removal Was 80% of 150 Ppm, Corresponding to a Mass Flux of 45 Mg/(Min·m2). the Observed Mass Flux through the HFMM during Biofiltration Also Rose, to 0.4 Mg/(Min·m2). Because the HFMM Had …
