GEA membrane filtration systems are used throughout industry. In many applications they have taken over from the more traditional technologies of centrifugal separation, evaporation and coagulation to provide significant benefits in terms of efficiency, product quality and sustainability.The GEA Group provides a wide range of processing technology allowing complete process lines, incorporating filtration plants, to be supplied from a single source. Some typical applications are listed on this page
Beer Recovery Unit
GEA cross-flow filtration with robust ceramic membranes are used for the effective recovery of beer from tank bottoms. Modular plants are supplied on compact skids in three standard sizes with processing capacities of approximately 250 hl, 500 hl and 1000 hl per day depending on the dry solids content of the product.
CIP Recovery Unit
The cleaning solutions are recirculated over tank farms until the impurity load is so high that the solutions have to be treated or dumped. These spent CIP solutions are mainly consisting of a sodium hydroxide solution of 2 - 4 % contaminated with organic matters - depending on the customer's process these might be proteins, sugars, colorants, etc.
Waste-free beer filtration with ceramic cross-flow membranes. Clearamic BeerFiltration is the first waste-free beer filtration process. Filter aids can be completely omitted. Sustainable and at the same time cost-cutting process management is thus supported at the critical point. In parallel with this, the process fulfils the consumer desire for crystal clear beer in permanently consistent quality. As the studies have shown, the beer quality remains consistently high with clearamic BeerFiltration.
COLDSAN™ - Cold Sanitation of Cheese Brine
Salt brine is used to cure many different varieties of cheese. Its microbiological composition is as important as its salt concentration in cheese making. Since disposal of salt brine is very expensive and often prohibited due to the high salt content, it is preferred to be recovered and reused, which makes brine cold sanitation one of the best quality improvements in cheese factories.
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 be achieved.
Custom-Designed Filtration Plants
GEA custom designs membrane filtration systems that best utilize the technologies of microfiltration, ultrafiltration, nanofiltration, or reverse osmosis for each customer's specific application.
De-Alcoholization Membrane Unit
In addition to the evaporation technology for the de-alcoholization of beer which has proven for many years, GEA offers an efficient process for the de-alcoholization of small feed rates by means of reverse-osmosis membrane filtration.
Membrane Unit to Produce FAB
As a basic substance for so-called FAB (flavored alcoholic beverages), a discolored and purified water-alcohol mixture is used. The basic material is beer (fermented alcohol bases). Undesirable ingredients, such as sugar, salts and long-chain color and aroma components are separated by cross-flow filtration.
