Some processes are improved with the introduction of nitrogen into the water or fluid. Ultrasonic and megasonic cleaning, for example, is improved if the oxygen is removed but some nitrogen is added to the water. Liqui-Cel® Membrane Contactors offer the perfect solution as they can deoxygenate and complete a controlled nitrogenation step at the same time.

The food & beverage industry also adds nitrogen to liquids in various processes. Nitrogenation is typically a step used in beverage processing if more bubbles or a thicker ‘head’ or foam layer on top of the beer is desired. Membrane Contactors offer an easy in-line step where nitrogen can be added in a controlled diffusion process that produces a more stable end product.

Mansfield Brewery Uses Liqui-Cel® Membrane Contactors to Nitrogenate Beer
Nitrogen is added to beer with Liqui-Cel® Contactors to control CO2 content and produce a smooth keg beer that mimics cask–conditioned beer while maintaining the ‘head’ characteristics of a keg beer.
