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 …

On the Morning of April 28, 1997, a Sinkhole Developed Beneath a Burlington Northern Santa Fe Railway Track. the Sinkhole Caused the Derailment of 22 Railroad Cars, Spilling Diesel Fuel from the Engines that Ignited, Resulting in a Fire and Injuries to Railroad Personnel. Railroad Personnel Filled the Sinkhole with About 500 Cubic Yards of Rock Fill, and Traffic Resumed While a Subsurface Study Was Carried Out. the Study Resulted in a Grouting Program Where 40 to 50 Cubic Yards of Grout Were Injected into the Subsurface. in August of 1999, the Track Subsided Again. a Second Investigation Conducted in …
