The harvesting of bacteria after the fermentation takes place in a separator. In the pharmaceutical plant a qualified nozzle separator is available. By using different nozzle diameters the strain-specific ideal concentration result can be achieved and the process yield can be kept high.

Both the pipelines and also the separator are CIP and SIP compliant. A concentration coefficient of 25 or 30 is reached. Wastewater is chemically and thermally inactivated.
