Process for the separation of biotechnologically produced valuable materials from a fermenter broth by crossflow micro- and/or ultrafiltration |
摘要 |
The invention is a process for the separation of biotechnologically produced valuable materials from a fermenter broth by crossflow microfiltration and/or ultrafiltration, in which at least two modules arranged in series and fitted with porous membranes are used per stage, to produce concentrate and a permeate which contains the valuable material. The pressure of the permeate is controlled so that the absolute pressure on the permeate side is at different absolute pressure in each module.
