There have been few studies of the dynamic membrane formed on a porous ceramic tube for the purpose of ultra filtration. The results of a study of the possibility of such a dynamic membrane for ultra filtration are described in this paper.
We found that a solution of ovalbumin, a kind of protein, formed an ultra filtration membrane and also that flux and cut-off molecular weight were controlled by the ovalbumin concentration. Because the mass transfer coefficients determined by the velocity variation method agreed very well with the Le veque correlations, the effect of concentration polarization of the ovalbumin on porous ceramic tube has been corrected. Consequently, membranes having various observed rejections showed the same true rejection after computation by this correlation.
The dynamic membrane formed by ovalbumin had sufficiently good performance as a ultra filtration membrane.
