Reducing disposal costs and recovering oil residues
Waste water from refining processes is frequently collected in lagoons or waste water ponds. The viscosity of the waste in these ponds can vary considerably dependent upon the water, oil and solid content. GEA decanters represent an ideal technology for treating waste water. The decanters reliably separate oil and fine sediments from the waste water, enabling the recovery of valuable oil residues, which also increases profitability. Reduced volumes of waste water means lower disposal costs, and our decanters adapt automatically to fluctuating feed conditions, so can achieve optimal results, even when the solids concentration of the waste water changes.
High performance separators for clean water
Downstream of decanter treatment, GEA’s high-performance separators can be applied to treat the aqueous phase that is still contaminated with oil. Our separators ensure that a residual oil content of less than 15 ppm is achieved in the aqueous phase, to meet regulatory environmental requirements.

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.

The breakthrough that changed spray drying
In 1976, NIRO engineers responded to a competitive challenge by rethinking what spray drying could do. Their idea became the multi-stage dryer MSD. Fifty years later, the same fundamental principle helps turn liquids into the powders used in essential nutrition products and important medicines around the world. Refined through decades of engineering expertise, customer insight and continuous development, MSD is a story of innovation with lasting impact.
Beyond the machine: unlocking better plant performance
An efficient machine does not automatically make an efficient factory. Real improvement often starts by looking beyond individual equipment and understanding how processes, energy systems and operating decisions affect one another. It’s a holistic approach designed to uncover opportunities that might otherwise be missed.
How a valve reshapes the way food and drinks are made
In food and beverage plants, valves are commonly operated using compressed air. GEA Hydract® Actuation Technology moves valves with water instead, in a closed, digitally controlled circuit. The result is a valve that can be held exactly in place and steered in fine-tuned steps. This results in lower energy use and greater control.
