NX Filtration N : Benefits of NX Filtration’s Nanofiltration Dealcoholisation Process

NX Filtration's hollow fiber nanofiltration membranes allow small molecules, such as water and ethanol, to pass through, while effectively retaining and preserving complex and delicate components like flavour, aroma and colour at low pressure and low temperature. During the batch process, the beer is concentrated to 40% of its initial volume, followed by replenishment with deaerated water to restore the original volume. The major advantage compared with traditional distillation methods is that nanofiltration selectively removes ethanol without compromising the sensory experience. This allows brewers to create low-alcohol or alcohol-free versions that closely resemble the characteristics of the original beers.

The efficiency of NX Filtration's nanofiltration process is another notable and sustainable advantage. Compared to conventional distillation techniques, dNF requires significantly less energy, resulting in reduced production costs and environmental impact. And the scalability of the technology makes it suitable for small- and largescale breweries, enabling seamless integration into existing manufacturing processes.
