Membrane Deaeration System MWD

Compact deaeration with membranesThe Membrane Degassing System (MWD) degasses water using highly efficient hollow fiber membrane modules to achieve residual oxygen levels below 10 ppb. Thanks to its compact design, the system can be installed even in spaces with low ceilings. For efficient results, we recommend regular replacement of the membrane modules.

How does the MWD work?In the modules, water flows around the hydrophobic hollow fibers on the outside, while inside, the stripping gas flows in the opposite direction. The hollow fibers create an extremely large contact surface between the water to be degassed and the stripping gas, allowing gases to pass through but not water.

The vacuum created on the gas side, approximately 65 mbar, removes the gas mixture from the modules. Simultaneously, the vacuum and stripping gas create a significant partial pressure difference, causing oxygen molecules to diffuse from the water into the vacuum. Carbon dioxide or nitrogen can be used as the stripping gas.

By arranging the membrane modules in parallel and in series, nearly any capacity and residual oxygen levels can be achieved.

Why should you choose the MWD?

  • Lowt oxygen values: Our product ensure outstanding quality with oxygen levels of less than 10 ppb.
  • Low CO2 consumption: Our system consumes less than 0.6 g/l CO2, saving costs and minimizing environmental impact.
  • Efficient vacuum system: The corovac vacuum system saves water and contributes to sustainability.
  • Energy efficiency: Thanks to the FLOW ADAPT algorithm, degassing performance adapts to the buffer tank‘s fill level, saving energy and reducing CO2 emissions.
  • Easy integration: The system is pre-assembled, pre-wired, and tested.
  • Fully automatic operation: Intuitive control with the corosys compass. Alternatively, the system can be fully integrated into your process control system.
  • Everywhere in view: With our Smart Machine operational data acquisition, you have access to operational data and reports from anywhere.
