بهینه سازی بیوراکتور دوفازی همزن‌دار به منظور حذف بخارات بنزن، تولوئن و زایلن(BTX) از جریان هوا
Introduction: In real Conditions, pollution emission are mostly released as mixed components rather than a single pure emission of the chemicals. In this study, a miniature stirred tank bioreactor was optimized for treatment of waste gas containing BTX (benzene, toluene and xylene). . Material and Method: The sludge of an oil refinery was sampled based on the assumption that it contains BTX-d...

Introduction: Human and environment exposed to harmful factors, as the result of industrial pollutants. Volatile organic compounds (VOCs) play important role in photochemical reactions in troposphere layer of atmosphere and results in production of ozone and photochemical oxidants. .Material and Method: In this study, a miniature stirred tank bioreactor was designed for treatment of waste gas...
متن کاملBiodegradation of high concentrations of benzene vapors in a two phase partition stirred tank bioreactor
The present study examined the biodegradation rate of benzene vapors in a two phase stirred tank bioreactor by a bacterial consortium obtained from wastewater of an oil industry refinery house. Initially, the ability of the microbial consortium for degrading benzene was evaluated before running the bioreactor. The gaseous samples from inlet and outlet of bioreactor were directly injected into a...
متن کاملOxygen transfer in three-phase airlift and stirred tank reactors using silicone oil as transfer vector
The use of organic liquids as vectors to enhance mass transfer has been applied since the 1970s. However, mass transfer in three-phase reactors is only partially understood. This paper aimed to characterize oxygen transfer in three-phase reactors containing air as gas, silicone oil as vector andwater as aqueous phase. Amass transfermodel that considers separately air/vector, vector/water and ai...
متن کاملGaseous hexane biodegradation by Fusarium solani in two liquid phase packed-bed and stirred-tank bioreactors.
Biofiltration of hydrophobic volatile pollutants is intrinsically limited by poor transfer of the pollutants from the gaseous to the liquid biotic phase, where biodegradation occurs. This study was conducted to evaluate the potential of silicone oil for enhancing the transport and subsequent biodegradation of hexane by the fungus Fusarium solani in various bioreactor configurations. Silicone oi...
