Effluents from cooling and treatment processes
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.
Reliable and robust even under extreme conditions
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.
Lower disposal costs and reduced fresh water consumption
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.

Absorption & Gas Scrubbing
GEA supplies scrubbers for an efficient multi-pollutant cleaning of process-and-exhaust gases for various applications.
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...
Jet pumps
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.
Particulate Removal (Dedusting)
Efficient dedusting of flue and exhaust gas with GEA´s reliable filtration and separation systems.

The water equation
Across Europe, drought is a recurring reality – and no longer confined to the south. While water increasingly shapes where industries locate, its value is determined by local context. There are many technological routes to water efficiency in industrial processes, but location, energy needs and other factors are also key.
