Mass transfer in a membrane aerated biofilm.
We present experimental results of mass transfer of a non reactive tracer gas (neon) measured in aerobic heterotrophic biofilm developed from activated sludge. Biofilms are grown in various hydrodynamic conditions and the effective diffusivity is used to quantify the mass transfer through the biofilm. Beyond some cross-flow conditions, the effective diffusivity through the biofilm seems larger ...
متن کاملMultidimensional modeling of biofilm development and fluid dynamics in a hydrogen-based, membrane biofilm reactor (MBfR).
A two-dimensional, particle-based biofilm model coupled with mass transport and computational fluid dynamics was developed to simulate autotrophic denitrification in a spiral-wound membrane biofilm reactor (MBfR), where hydrogen is supplied via hollow-fiber membrane fabric. The spiral-wound configuration consists of alternating layers of plastic spacer net and membrane fabric that create rows o...
متن کاملa new membrane - aerated biofilm reactor for low energy wastewater treatment : pilot results
A new hybrid membrane-aerated biofilm reactor (MABR) technology that enables energy-neutral treatment of municipal wastewater is introduced. The process, which removes nitrogen using conventional nitrificationdenitrification, was demonstrated at pilot-scale, treating primary effluent. The new MABR membrane product can operate in a high mixed liquor suspended solids (MLSS) environment, making it...
