ArcelorMittal needed to treat the high sulphate concentrated mine water in order to meet the environmental regulations and wanted to re-use the treated water as its water source for industrial applications. For these purposes, Veolia concluded a design, build and operate contract with ArcelorMittal for its wastewater treatment facilities in 1998.
The system comprises a nanofiltration plant with a capacity of 5,500 m3/d. The contractual requirements have been met and exceeded at all times. Nanofiltered water is used by all cold rolling and coating units of the Arcelor Mittal steel mills at Florange. With a production capacity of approximately 3 million metric tons per year, the Florange site specializes in flat steel, mainly for the automotive sector.
