Mass transport through biocatalytic membrane reactor

Biocatalytic membrane reactors for the removal of recalcitrant and emerging pollutants from wastewater

“…The diffusive and convective mass transport through biocatalytic membrane layer and with biochemical reactions pertaining to enzymatic membrane reactors used in food and pharmaceutical industries for hydrolysis of macromolecules (proteins, poly-and oligo-saccharides, lipids, etc.) have been investigated (Nagy, 2009 ;Nagy and Kulcsar, 2009 ;Noworyta and TrusekHolownia, 2004 ;Trusek-Holownia and Noworyta, 2004 ). However, fewer models on enzymatic membrane reactors particularly utilized for emerging pollutant degradation have been reported.…”

Advances in Bioprocess Technology

“…Several assumptions related to the mass transfer in the system were made for the coupled reaction-diffusion model; (1) the effect of axial flow gradient on the radial diffusion is negligible; (2) Fick's law is applied for the diffusion of substrate; (3) the fluid properties is constant throughout the boundary condition of the membrane; and (4) Eddy diffusion is insignificant (Long et al 2003;Nagy and Kulcsár 2009;Lau 2013). The DEKR model derived in the previous section was incorporated together with the diffusion mechanism in order to obtain a complete DEKR model.…”

From “Black Box” to a Real Description of Overall Mass Transport through Membrane and Boundary Layers

“…Diffusion plus convection mass transport can easily be extended to those accompanied by chemical or biochemical reactions [23,24,25,26]. When investigating membrane performance in the presence of convective velocity, the importance of the absence or presence of the sweeping phase on the permeation side of the membrane [11] (pp.…”
