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 process can be used for manufacturing different drinks in the brewery, such as onerous seltzer.
GEA AromaPlus makes use of a filtration know-how with particular polymer membranes to separate alcohol and water from the opposite components by means of reverse osmosis; these components are crucial for the aroma, colour and turbidity of the final product. Adding the model new PRO technology to the water-saving CO2 blow-out perform and the selective membrane which is already applied within the AromaPlus unit design, GEA saves greater than two thirds and up to one hundred pc of the fresh water used for diafiltration.
“Our newest AromaPlus era combines the pattern towards zero.0% beer with the objective of decreasing water in production,” says Ralf Scheibner, filtration expert at GEA, underneath whose management the GEA AromaPlus has been further developed. “In reality, a membrane process requires lots of water to flush out the alcohol. pressure gauge 10 bar is an issue for breweries with a restricted deoxygenized water availability. Our new PRO answer is a crucial step for them towards recent water neutrality in manufacturing processes.”

The complete dealcoholization system GEA AromaPlus is mounted on a frame. It contains the filtration modules and reverse osmosis membranes, pumps for media transfer and system stress build-up, the complete inner piping, a CIP dosing unit put in subsequent to the system, and the management tools required for semi-automated operation. – Image: GEA/Mike Henning.
While breweries want much less fresh water for the diafiltration step, the permeate leaving the system can be reused as a useful by-product. Due to its decrease quantity, it has a higher alcohol content and might due to this fact function a base for alcoholic mixed drinks and newer drinks, similar to onerous seltzer, or could be reused throughout the brewery itself.
“The Corona pandemic confirmed that breweries whose manufacturing services offered the pliability to course of other beverages coped best with the drop in demand. GEA AromaPlus is a good instance of how customers can gear their plants toward excessive demand dynamics,” says Scheibner. Originally designed for the dealcoholization of beer right down to 0.0%, the system may also be used used for different non-alcoholic beverages, corresponding to 0.0% cider.
