Industrial effluent
Industrial waste water
Numerous sectors of the chemicals and pharmaceuticals industries process organic and inorganic fluids. Many of these fluids, such as solvents, have inherent value, and others contain valuable chemical compounds or other substances, such as minerals or nutrients, including proteins. The water itself is also a valuable resource that should be reclaimed and recycled where possible.
GEA is a world-leading manufacturer of thermal-mechanical process engineering, with core competencies in evaporation, distillation and membrane filtration. We can also design tailor-made plants for the special requirements, including additional upstream or downstream process steps. Using our processes and plants you can be guaranteed to achieve optimum results for the water quality and for the recovery of valuable substances.
GEA’s decanters, separators and cross-flow filtration technologies represent effective mechanical separation solutions for the first stage of separating industrial fluids. After membrane pre-treatment, all types of evaporators are used to partially recover the valuable liquid stream and to concentrate the remaining waste stream.The system is commonly combined with vapor wash columns and distillation columns to purify the recovered water as far as possible. Waste heat resources and mechanical vapor recompression make sure that energy consumption is minimized and heat recovery optimized.

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".

A new recipe for indulgence
What if your favorite chocolate didn’t require cocoa beans and your coffee was locally produced? As climate disruption, price hikes and ethical concerns hit two of our most beloved indulgences, scientists are reimagining how we produce them – using microbes, not monocultures. The goal: preserve the flavor and properties of coffee and chocolate while minimizing carbon emissions and improving food resilience.
Fueling the circular economy in shipping
Ports now compete not just on logistics, but on sustainability. At Greece’s Piraeus port, an advanced processing and recovery facility recycles ship waste oil into fuel. Equipped with GEA’s high-performance centrifuges, it sets a new benchmark for state-of-the-art, environmentally responsible port operations.
Closing the loop: key lessons for breweries from OeTTINGER
The 2022 CO2 shortage forced breweries to review their dependency on global supply chains. Many were forced to close, unable to carbonate their products. At its breweries in Germany, OeTTINGER GETRÄNKE is turning its own CO2 into a powerful lever for independence and sustainability – with the help of CO2 recovery technology from GEA.
