Biological treatment of contaminated air with toluene in an airlift reactor

Abstract

Volatile organic compounds (VOC'S) are some of the main atmospheric emissions along with particle matter. The most common VOC'S are alcohols, ketones, aliphatic hydrocarbons and aromatic hydrocarbons BTEX (benzene, toluene, ethylbenzene and xylene isomers) being generated

Bioremediation strategies for chromium removal: Current research, scale-up approach and future perspectives

“…The main advantages of ALRs are: no moving parts, low power consumption, high heat and mass transfer, maintenance of solids in suspension, homogeneous shear, rapid mixing, increased oxygen solubility, high homogenization efficiency and low shear stress to cells, easy sterilization, low contamination risk Gavrilescu, 2010, 2011;Luo and Dahhan, 2007;Gavrilescu and Tudose, 1998). Numerous studies on treatment technologies based on biosorption, biofilm-mediated bioremediation, suspended microorganism processes highlighted the significant advantages of ALRs to remove different pollutants from contaminated fluid (wastewater and gaseous) streams (Nikakhtari and Hill, 2008;Vergara-Fern andez et al, 2008). Morales-Barrera and Cristiani-Urbina (2006,2015), pointed out that the microorganism Trichoderma viride and Hypocrea tawa showed a high biosorption capacity when cultivated in an airlift and verified that shaking using a STR caused fragmentation of the mycelium with a negative effect on biosorption.…”
