GEA’s water-saving membrane system for non-alcoholic beer

GEA AromaPlus PRO reduces the water consumption for diafiltration during dealcoholization by up to one hundred pc. The alcoholic base produced as a by-product of the filtration course of can be used for manufacturing other beverages in the brewery, such as exhausting seltzer.
GEA AromaPlus uses a filtration expertise with special polymer membranes to separate alcohol and water from the opposite components via reverse osmosis; these components are essential for the aroma, colour and turbidity of the final product. Adding the new PRO know-how to the water-saving CO2 blow-out function and the selective membrane which is already applied in the AromaPlus unit design, GEA saves more than two thirds and up to 100% of the recent water used for diafiltration.
“Our newest AromaPlus era combines the development towards zero.0% beer with the aim of decreasing water in production,” says Ralf Scheibner, filtration professional at GEA, under whose leadership the GEA AromaPlus has been additional developed. “In reality, a membrane process requires plenty of water to flush out the alcohol. That is an issue for breweries with a restricted deoxygenized water availability. Our new PRO resolution is an important step for them in direction of fresh water neutrality in production processes.”
The complete dealcoholization system GEA AromaPlus is mounted on a body. It contains the filtration modules and reverse osmosis membranes, pumps for media switch and system stress build-up, the whole internal piping, a CIP dosing unit put in next to the system, and the control gear required for semi-automated operation. – Image: GEA/Mike Henning.
While breweries need less contemporary water for the diafiltration step, the permeate leaving the system can be reused as a useful by-product. Feast to its lower quantity, it has a better alcohol content and may due to this fact serve as a base for alcoholic blended drinks and newer beverages, such as hard seltzer, or may be reused inside the brewery itself.
“The Corona pandemic showed that breweries whose production services provided the flexibility to course of other beverages coped greatest with the drop in demand. GEA AromaPlus is a good example of how prospects can gear their vegetation towards excessive demand dynamics,” says Scheibner. Originally designed for the dealcoholization of beer all the method down to zero.0%, the system can also be used used for other non-alcoholic drinks, similar to 0.0% cider.
