Understanding oily wastewater
Oily wastewater is commonly generated in refineries, tank terminals and petrochemical facilities whenever oil and water come into contact during processing, cleaning or storage activities.
Typical sources include:
- Tank cleaning operations
- Slop water systems
- Refinery process water
- Fuel and lube oil leaks
- Equipment washdown water
- Cooling water contamination
- Drainage from separators and tanks
Without proper treatment, oil and suspended solids must be removed before reuse, discharge or further processing. Increasing environmental requirements and rising disposal costs make efficient oily wastewater treatment more important than ever.
Oily wastewater treatment with centrifugal separation
GEA centrifugal separators continuously remove free oil and suspended solids from oily wastewater streams.
The recovered hydrocarbon phase can often be returned to the process or utilized elsewhere, while the treated water stream can be sent to downstream polishing systems, biological treatment facilities or discharge systems depending on site requirements.
Compared with conventional settling systems, centrifugal separation offers faster separation, a smaller footprint and continuous operation with minimal operator intervention.
With decades of experience in treating oily water, bilge water and other hydrocarbon-contaminated wastewater streams, GEA helps operators reduce waste volumes, recover valuable resources and support environmental compliance.
Where oily wastewater treatment makes a difference
Whether generated during refinery operations, tank cleaning, product storage or utility processes, oily wastewater requires reliable treatment before reuse, discharge or further processing.
GEA solutions are applied in:
- Refineries
- Tank terminals
- Petrochemical facilities
- Fuel storage sites
- Utility and offsite systems
- Slop water treatment systems
- Industrial wastewater treatment facilities
Turn wastewater into a recoverable resource
GEA's oily wastewater treatment solutions help recover valuable hydrocarbons, reduce waste volumes and support efficient downstream water treatment.
Let's discuss your oily wastewater challenge.

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...

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.
