Separation of Yeast by Cross-flow Filtration with Backwashing

概要

論文の詳細を見る
The following results were obtained at the separation of yeast by cross-flow filtration from fermentation broth or yeast suspensions with or without backwashing by the filtrate, using micro-porous membranes : 1) the first stage of the filtration process was described by the standard blocking filtration model, 2) the mean filtration flux in one filtration cycle was kept almost constant for at least 3 h by backwashing, 3) the mean filtration flux with backwashing was roughly estimated from the results of filtration without backwashing, and 4) the filtration flux at certain yeast concentration in concentrating the yeast was not so much affected by the previous concentration path, and almost agreed with that in the filtration of a constant concentration at the same concentration.
