MembranLuftkontaktoren

MembranLuftkontaktoren, which translates to membrane air contactor, is a passive device used for gas-liquid exchange. It consists of a hydrophobic membrane that separates a liquid phase from a gas phase. The pores of the membrane are too small for liquid to pass through, but large enough for gases to diffuse across. This selective permeability allows for efficient transfer of gases between the two phases without direct contact.

These devices find applications in various fields, including water treatment, where they can be used for degassing or stripping dissolved gases from water, such as oxygen or carbon dioxide. In the medical field, they are employed in artificial lungs or dialysis machines for gas exchange in blood. They can also be utilized in industrial processes for gas purification or separation. The effectiveness of a MembranLuftkontaktor depends on factors such as the membrane material, pore size, surface area, and the flow rates of the gas and liquid. The hydrophobic nature of the membrane prevents wetting, which is crucial for maintaining its performance over time. Different membrane configurations, like hollow fibers or flat sheets, are available to suit specific application requirements.
