Benefits of our centrifuges
• Recover valuable oil for reuse or energy recovery
• Reduce disposal volumes and costs
• Remove solids and sludge efficiently
• Produce cleaner water streams for further treatment or discharge
• Continuous, automated operation with minimal maintenance
• Reduce chemical consumption compared to conventional treatment methods
• Compact footprint and easy to integrate into existing plants
Understanding industrial liquid waste
Industrial liquid waste streams can vary significantly in composition and may contain combinations of:
• Waste oil and used lubricants
• Oily wastewater
• Tank cleaning residues
• Bilge and MARPOL-related waste streams
• Process and wash waters
• Sludge-containing liquid waste
The composition of these streams can vary significantly, making efficient oil-water-solids separation essential for both environmental compliance and cost-efficient operation.
Recovering value from liquid waste streams
Many industrial liquid waste streams still contain valuable hydrocarbons that can be recovered for reuse, energy recovery or further processing. At the same time, water, sludge and suspended solids must be removed to reduce disposal volumes and support downstream treatment.
GEA decanter centrifuges and separators provide highly efficient separation of oil, water and solids. Decanters remove sludge and coarse solids, while separators polish the liquid phases by removing fine solids and residual water. This enables maximum oil recovery, cleaner water streams and significantly reduced waste volumes.
Compared with settling tanks or conventional filtration systems, centrifugal separation offers continuous operation, automatic solids discharge and reduced maintenance requirements.
Typical applications
• Waste oil recovery
• Oily wastewater treatment
• Bilge water treatment
• MARPOL waste processing
• Tank cleaning residues
• Industrial wash waters
• Sludge-containing liquid waste
• Waste collection and recycling facilities

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.
Liquid Mixers
Mixing is a vital process in the production of a diverse range of products in a wide range of industries. Based on our extensive experience and technological know-how, GEA offers a variety of batch, continuous and in-house custom designed mixing solutions for unique applications that meet specific customer needs.

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.
