A new paper entitled "Capillary membrane bioreactor for abatement of low soluble compounds in waste gas" by E. Morral, C. Lao-Luque, D. Gabriel, X. Gamisans and A.D. Dorado has been published in Journal of Chemical Technology and Biotechnology (2018), 93, 548-556.
In membrane biological reactors (MBRs), two phases (gas and liquid) are physically separated by the membrane. Pollutants dissolved in air pass through the membrane by diffusion and are degraded by the microorganisms attached on the other side where the culture medium is continuously recycled. Membrane bioreactors for waste gas treatment are a promising alternative for hydrophobic compounds. The paper now published in JCTB shows the capabilities of MBRs for the treatment of waste gases containing toluene, iso-octane and hexane. Our results demonstrate that a commercial membrane for wastewater treatment can be adapted for biological gas treatment, improving efficiencies and becoming a potential alternative to conventional biological treatment technologies.
