Abstract

Process for supplying oxygen from fermentation plant in which the oxygen is introduced without bubbles through at least one pore-free plastic membrane with a flexible fabric reinforcement, and device for implementing the process and for its use. The oxygen required for performance of the bio-process is fed in completely or partly free of bubbles through at least one fabric-reinforced and pore-free plastic membrane mounted on support elements. For this purpose, gas exchangers (33) having plastic pore-free membranes (4) mounted on supports (32) are arranged in the fermentation plant, said membranes being reinforced with a flexible fabric (6).
