GEOLIDE Wastewater Treatment Complex in Marseille uses DCS CENTUM and Exaquantum

Case Study by Yokogawa: Constructed in 1987, the GEOLIDE wastewater purification plant treats up to 220,000 m3 of wastewater per day (86 million m3 per year) for the city of Marseille (population 1,860,000) and 16 towns in the surrounding area. The plant has been operated since 2001 by Seramm, which is a subsidiary of the French water supply and wastewater treatment company Lyonnaise des Eaux.

Although located in the Marseilles city center, the GEOLIDE wastewater purification plant has minimal impact on the surrounding area as it is built almost entirely underground and releases none of the objectionable odors that are normally associated with facilities of this type. Originally configured to provide just primary water treatment using physical and chemical processes, the GEOLIDE plant was revamped in 2008 to provide advanced biological treatment processes. Water treated by this facility is discharged into the sea, and sludge is transported 6 km to the Cayolle treatment plant.

As part of the revamping process that was completed in 2008, Yokogawa France was asked to upgrade the GEOLIDE plant’s existing Yokogawa CENTUM V production control system (PCS) to the CENTUM CS3000 PCS and to install the Exaquantum plant information management system (PIMS). This work was carried out in collaboration with Veolia Environnment and Suez Environnment.
