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 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.
