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

GEA AromaPlus PRO reduces the water consumption for diafiltration throughout dealcoholization by up to 100%. The alcoholic base produced as a by-product of the filtration process can be utilized for manufacturing different drinks within the brewery, similar to hard seltzer.
GEA AromaPlus makes use of a filtration technology with particular polymer membranes to separate alcohol and water from the other ingredients by means of reverse osmosis; these elements are essential for the aroma, color and turbidity of the ultimate product. Adding the new PRO expertise to the water-saving CO2 blow-out perform and the selective membrane which is already carried out in the AromaPlus unit design, GEA saves more than two thirds and up to 100 percent of the fresh water used for diafiltration.
“Our latest AromaPlus era combines the pattern towards 0.0% beer with the goal of lowering water in production,” says Ralf Scheibner, filtration expert at GEA, beneath whose management the GEA AromaPlus has been additional developed. “In truth, a membrane process requires a lot of water to flush out the alcohol. That is an issue for breweries with a limited deoxygenized water availability. Our new PRO resolution is a vital step for them towards recent water neutrality in manufacturing processes.”

While breweries want less fresh water for the diafiltration step, the permeate leaving the system can be reused as a priceless by-product. Due to its decrease volume, it has a better alcohol content and may due to this fact serve as a base for alcoholic blended drinks and newer drinks, similar to exhausting seltzer, or could be reused within the brewery itself.
“The Corona pandemic confirmed that breweries whose manufacturing services offered the flexibleness to process other beverages coped finest with the drop in demand. GEA AromaPlus is a good example of how clients can gear their plants toward high demand dynamics,” says Scheibner. Originally designed for the dealcoholization of beer right down to 0.0%, the system can be used used for different non-alcoholic drinks, similar to 0.0% cider.
