Data and model for progressive fouling in cross-flow microfiltration of yeast on three industrial mineral membranes
- Ecole Nationale Superieure des Mines de Paris (France). Centre Reacteurs et Processus
The variation of permeation flow as a function of time was experimentally studied from the initial three fast transient to its final stabilization in the case of filtration of a yeast suspension using industrial microfiltration membranes from Tech-Sep S.A.(01703 Miribel, France), SCT S.A. (65460 Bazet, France), and Le Carbone-Lorraine S.A.(54530 Pagny sur Moselle, France) with the same nominal mean pore diameter (0.2 [mu]m). The influences of three operating conditions, concentration of yeast, transmembrane pressure, and velocity, were systematically obtained. The behaviors of the three membranes differ, as expected, because their structures as characterized by rugosity measurements and electron micrographs are very different. The correlation of the results is based on a two-term equation, adding a transient term to the steady flow J[sub 1] initially equal to the initial permeate flow rate J[sub 0] before any fouling minus J[sub 1]. The parameters in the correlation of J[sub 1] and the transient flow term were obtained by statistical analysis of experimental results and yield a representation of the experimental results with an error on the order of 10%.
