OPTIMIZING BTEX BIODEGRADATION UNDER DENITRIFYING CONDITIONS [PDF]

Environmental Toxicology and Chemistry, 1991
Abstract Laboratory tests were conducted to determine optimum conditions for benzene, toluene, ethylbenzene, and xylene (collectively known as BTEX) biodegradation by aquifer microorganisms under denitrifying conditions. Microcosms, constructed with aquifer samples from Traverse City, Michigan, were amended with selected concentrations ...

BTEX degradation in a cold-climate wetland system

Water Science and Technology, 2005
A pilot-scale subsurface vertical-flow wetland system was constructed at the former BP Refinery in Casper, Wyoming in order to determine benzene, toluene, ethylbenzene and xylene (BTEX) degradation rates in a cold-climate application. The pilot system, consisting of 4 cells, each dosed at a nominal flow rate of 5.4 cubic metres per day, was operated ...

BTEX removal with bioelectrochemical systems

, 2017
Benzene, toluene, ethylbenzene and xylenes (BTEX) are hazardous contaminants that can accidentally impact groundwater. Biological strategies can be used to remove BTEX compounds usually by adding oxygen to sustain the aerobic degradation. However, this approach can be expensive and technically difficult.

Predictors of indoor BTEX concentrations in Canadian residences.

Health reports, 2013
Benzene, toluene, ethylbenzene and m-, p-xylenesand o-xylene (BTEX) are a group of volatile organic compounds that originate from similar sources. Given the potentially negative health implications of BTEX exposure and their prevalence in residential indoor air, it is important to understand typical residential concentrations and identify predictors ...

Biofiltration of BTEX waste gases

, 2009
A comparison of biofilter performance under different temperature conditions is of particular importance for the application and commercialization of biofiltration technology due to the fact that many waste gas streams are at elevated temperatures. The efficacy of higher temperature biofiltration reactors, therefore, has important practical and cost ...
