Membrane Filtration Technology for the Production of Alcohol-free Beer
GEA AromaPlus Membrane Dealcoholization Unit
Supporting small to large feed rates, and configurable for both batch and continuous processes, the dedicated AromaPlus system is built on our reverse osmosis (RO) membrane filtration technology. Whichever process you choose, the AromaPlus technology removes alcohol to 0.5% or to 0.05% ABV.
Frame-mounted and ready for installation, the AromaPlus unit includes filtration modules fitted with special reverse osmosis membranes, pumps, internal piping, a clean-in-place (CIP) dosing unit and control technology for semi-automatic operation. The unit layout is modular, enabling the alcohol content of the beer, desired degree of dealcoholization and other factors to be adapted according to the specific process. Depending on their size, AromaPlus units are designed to batch process 50 to ≥ 1.000 hL per day, although larger dealcoholization units for continuous processing are available.
Dealcoholization by pressure
Reverse osmosis works at filtration temperatures of approximately 10 to 15 °C, presenting no thermal stress to the beer. The composite membranes allow water and alcohol to pass through and, as such, essential ingredients that comprise the aroma, color and turbidity are retained. GEA uses thin-film polymer membranes because they have a higher chemical resistance than the cellulose acetate membranes originally used for dealcoholization.
Dealcoholization of craft beer
The AromaPlus system is also cost-effective, so that even smaller breweries can consider investing in a dedicated dealcoholization unit on site.

CIP Recovery Unit
It is now possible to recover more than 90 percent of a spent caustic solution by using pH-resistant nanofiltration (NF) membranes. Benefits include reduced operating costs and better performance.
Condensate Polisher
Condensate from evaporation plants is used as boiler feed water, process, cooling, and rinsing water or is directly discharged into a drainage ditch.
For this purpose, the condensate must be purified. Impurities in the condensate can be removed by membrane filtration, in the particular case by reverse osmosis, and high condensate qualities can ...
Membrane Unit to Produce FAB
GEA’s cross-flow membrane filtration units have been specifically designed to deliver a clear, colorless, tasteless and aroma-free neutral alcoholic base. The neutral alcohol base used in a hard seltzer derives from a fermentation process with no distillation step.
