Organic Acids
Organic acids are important chemical building blocks for producing polyesters, polyamides, plasticizers and solvents. They are also used in the preservation of food. GEA has leading expertise and experience in the concentration of final organic acid products, side-products and effluents from organic acid fermentation. We can offer a range of systems, solutions and plants tailored to specific applications.
The first stage in the process of organic acid concentration is biomass separation by decanters or membrane filtration units. The acids are then concentrated in evaporation plants. GEA offers decanter and membrane filtration systems for most applications, and our falling-film evaporation plants are often used to concentrate the acids. The separator technology is also commonly equipped with scrubbing columns for the separation of easily volatile components, or with stripping columns for the separation of ammonia.
The production process can generate large quantities of secondary flows with high salt content or high organic load, and these are also concentrated in evaporation plants. Because waste waters may be corrosive or coat equipment and components, GEA can provide falling film and forced circulation evaporation systems that are constructed using materials that will ensure long equipment life as well as efficient economic operation.

Centrifugal Separator
GEA separators are designed for liquid-based applications. Using centrifugal force, they are used for separating suspensions consisting of two or more phases of different densities, i.e. they can be used for liquid-liquid separation, for liquid-liquid-solid separation or for liquid-solid separation. They are equally as effective at separating liq...
Decanter Centrifuge
The decanter’s hour has come as soon as the solids content in the suspension to be processed is particularly high. These machines provide the benefits of high clarifying efficiency and maximum dewatering as well as the separation of liquids with the simultaneous removal of solids. The main requirements in this respect include a high bowl speed, a...
Distillation Test Facilities at Karlsruhe R&D Center
With state-of-the-art pilot plants and test benches our R & D Center is optimally equipped for testing in the fields of distillation technology.
Ejector Systems
Ejectors, are devices for the conveyance, compression or mixing of gases, vapors, liquids or solids in which a gaseous or liquid medium serves as the motive force. They are "pumps without moving parts".

Farmers reap benefits of tailored GEA batch milking system
Automated milking has become the first choice for many modern dairy farms. The benefits are compelling, and with a new batch milking solution from GEA, automated group milking for large dairy herds is possible without the need – and expense – of rebuilding existing facilities.
GEA earns EcoVadis Platinum again – with higher score
GEA has once again earned the highest rating – Platinum – in the globally recognized EcoVadis sustainability assessment. With a score of 92 out of 100, the machinery and plant manufacturer has improved significantly from last year’s result of 82 points. For the second year in a row, GEA ranks among the top one percent of more than 150,000 rated companies across 185 countries.
How Carlsberg keeps 10,000 valves in play
At Carlsberg’s Fredericia brewery, GEA VARIVENT valves are part of a long-game strategy. By reusing core valve bodies, retrofitting actuators and control tops, and planning maintenance around brewing seasons, Carlsberg extends asset life, reduces downtime and supports its ambitious water and sustainability targets.
