Industrial effluents

Olive oil mills

As a result of their high content of polyphenol, fatty acids and organic substances, effluents from olive oil production are posing an increasing environmental problem. It is true that modern production processes now make a major contribution towards reducing the volume of effluent. Nevertheless, it is still the case that approximately 200 liters of water must be used for each ton of processed olives; this effluent contains oil and extremely fine particles. In order to ensure the environmentally-sound treatment of these effluents, GEA supports industry with innovative technologies which not only considerably reduce the volume of effluent but also enable all residues to be virtually fully recycled, thus creating economic as well as ecological added value.
