Abstract
Official abstract text for this publication.
A device for degassing aqueous media has a first container containing medium to be degassed. A first line connects the first container to a degassing module and a second line connects the degassing module to a second container for receiving the degassed medium. A first non-return valve in the first line prevents backflow from the degassing module to the first container. A hydrophilic membrane in the second line prevents the passage of gas, and a branch between the degassing module and the hydrophilic membrane has a hydrophobic degassing filter for letting out gas. A third line is connected to the first line between the first container and the first non-return valve and to the second line between the second container and the hydrophilic membrane. A second non-return valve in the third line between the first non-return valve and the hydrophilic membrane prevents a flow towards the second container.
