Efficient process water treatment with GEA decanters
Concentrated to recycled sludge by means of settling or flotation processes, our powerful decanters treat the process water which is obtained in such a way that they reliably separate residual oil as well as micro-particles from the effluent so that high-quality olive oil can be produced and so that oil mills can considerably boost their yield. The process not only enables the volume of effluent to be reduced by 15 percent. It also reduces all parameters which are relevant for evaluating effluents; this means that effluent charges are also reduced.
Energy-efficient concentration using GEA concentration installations
As an environmentally-sound solution for the treatment of effluent from olive oil production, we also supply highly efficient concentration technology, with which the effluent can reliably be concentrated to 50% dry matter. The concentrate can subsequently be used as a fertilizer or, after the dry matter has been further increased, it can be incinerated and used for generating electrical energy. The evaporated water is condensed and can be reused as process water. GEA concentration installations can be entirely operated by way of using the waste heat of peripheral equipment and thus feature extremely energy-efficient operation.
- Environmentally-sound and added-value methods for treating effluents from olive oil production
- Processing with GEA decanters ensures a lower effluent load, reduced disposal costs and additional yield gains
- Energy-efficient concentration installations thanks to the use of waste heat for reliable concentration

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.
