  • Ensure the clearance of discharges into the natural environment.
  • Limit the impact on the environment.
  • Respect ecological standards. 

Adaptable solutions for all metallurgical players

Process water production

Many metals come from hydrometallurgical treatment for which we provide quality process water. Our innovative solutions also pretreat the water to ensure it complies with many types of facilities, as quality water optimizes equipment life and reduces maintenance costs.

Water reuse – Water treatment circularity

Our water treatment technologies are an essential asset for wastewater treatment and reuse. We help metallurgical industry leaders reduce their environmental impact. 

Companies in the metallurgical industry, well versed in environmental regulation compliance, expect to gain competitiveness and profitability through their water treatment processes. Our innovative solutions for recovery and reuse of water help our customers comply with regulations while ensuring a competitive advantage. 

Veolia Water Technologies' measurement tools and their environmental impact

Using our own tools and in-depth criteria, we can measure the impact of our customers' industrial activities. We can evaluate pollution generated by metal mining activities and resource requirements according to the location of the various production sites. This fine-tuned and precise analysis enables us to accurately determine both the real cost of water for our customers and their environmental impact.

Strong partnerships between world leaders

Rationalization solution for steel giant ArcelorMittal
Our expertise is recognized and highly sought after by the world's leading metallurgical groups, including ArcelorMittal.

Veolia Water Technologies is helping the steel giant reduce its environmental footprint at its São Francisco do Sul site in Brazil. Our water consumption rationalization solutions have helped the company comply with strict environmental regulations – enabling ArcelorMittal to respect local biodiversity while gaining competitiveness.


Metallurgical activities are among the most water-intensive industrial sectors in the world. We offer solutions to  optimize water resources, address the challenges related to water scarcity and meet the most stringent environmental standards.

FAQ about water solutions for metallurgical industries

Which water treatment processes are used for steel production?

The production of steel and metals requires the use of several water treatment processes, starting with process water treatment at the inlet for cooling circuits, steam production, surface treatment, electrolytic baths and gas treatment. This step is followed by effluent treatment for suspended solids (TSS), metals, total organic carbon (TOC) and specific pollutant removal. A final step is applied to treat effluent from wet gas.

What are the steps to treat water in metallurgy?

For process water, the main water treatment steps are raw water clarification, filtration, degassing and demineralization (ion exchange, reverse osmosis). Effluent treatment uses physico-chemical precipitation for metals removal, filtration (specific media and membranes) and evaporation for ultimate concentration before disposal (salinity management).

How can water be reused in the metallurgical industry?

Following appropriate treatment, wastewater can be reused for cooling and demineralized water production. Material recovery can also be considered in order to generate value from wastes (ammonia, nickel, cobalt, sodium sulphate, etc.). CAPEX and OPEX are estimated in order to find the best solutions considering waste management downstream.
