Arcelor Atlantique et Lorraine, Montataire - France

Veolia Water took responsibility for the water supply and the wastewater treatment of the Montataire site.

The client

A subsidiary of the worldwide steel group Arcelor, Arcelor Atlantique et Lorraine operates a plant in Montataire, specialized in cold-rolled flat products, both coated and uncoated.

The production of 1,400,000 tonnes per year of rolled steel requires a supply of raw water, softened water, demineralized water, high-pressure hot water, steam and compressed air.

The effluent and waste generated by the plant are treated on site in Sollac's dedicated facilities.

Client's needs

The goal of Arcelor Atlantique et Lorraine was to improve the economical, technical and environmental performances of its facilities.

In order to refocus on its core business, i.e. steel pickling, rolling and surface treatment, Arcelor Atlantique et Lorraine was looking for a partner to take over responsibility for the provision of utilities and the treatment and disposal of the plant's effluents and waste.

Our solution

In the frame of a Veolia Environnement multi-utilities contract, Veolia Water took responsibility for the water supply and the wastewater treatment of the Montataire site and acquired ownership of part of the facility and assets on Arcelor Atlantique et Lorraine's request.

To improve the treatment plant's overall performance, Veolia Water has contracted to optimize the water and wastewater treatment systems: renewal or replacement of equipment, remote monitoring, etc.

Technologies used:

  • Physico-chemical treatment of the wastewater,
  • Treatment of oily waste by phase separation,
  • Sludge treatment using a filter press.

Plant capacity:

  • Production of raw water: 3,000 m3 per hour
  • Production of softened water: 220 m3 per hour
  • Production of demineralized water: 120 m3 per hour
  • Wastewater treatment: 1,500 m3 per day
