Industrial effluents
Efficient effluent treatment, complying with extremely strict legal requirements, not only makes a contribution towards saving the environment; at the same time, it also helps to achieve a significant reduction in operating costs. The steel industry has recognized this potential, and therefore places its trust in the innovative system solutions of GEA. In the treatment of very contaminated effluents, our decanter centrifuges perform an excellent service, thereby setting standards in terms of reliability, cost-effectiveness and efficiency.
As a by-product of the steel industry, various production stages produce large quantities of effluent which are contaminated with dust, dissolved metal compounds, cleaning solutions and in particular insoluble inorganic substances. They are produced mainly in the course of flue gas scrubbing in foundries, in slag granulation and top gas cleaning; they occur in the form of emulsions from cooling circuits in forges and rolling mills, or are encountered as backwash water in a foundry’s own power stations.
Thanks to first-class engineering and the use of particularly high-quality materials, GEA decanters feature extremely robust design and are precisely tailored to meet the requirements encountered in the metal-working industry. They thus also provide maximum reliability even under extreme conditions, and with their high separating efficiency, they reliably ensure optimum solids dewatering as well as effluent treated in an environmentally sound manner.
The clarified concentrate can be recycled as wash water back into the production cycle, which significantly reduces the consumption of fresh water for steel production and processing. The dewatered solids on the other hand can be profitably recycled in a subsequent recycling process or their volume can be reduced, enabling them to be disposed of inexpensively.

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...
Efficient dedusting of flue and exhaust gas with GEA´s reliable filtration and separation systems.
Jet pumps, also referred to as ejectors, are devices for the conveyance, compression or mixing of gases, vapors, liquids or solids and for the production of vacuum in which a gaseous or liquid medium serves as the motive force.
GEA supplies scrubbers for an efficient multi-pollutant cleaning of process-and-exhaust gases for various applications.
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.
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.
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.
