Selective nickel/cobalt capture in processes and effluents
In the process industry nickel/cobalt pollution is frequently observed in the effluents. This occurs due to the materials used in the processes. French regulations have set a maximum threshold for nickel/cobalt concentration in discharged water and further restrictions are yet to come. Manufacturers are faced with the obligation to optimise their effluent treatments, which represents significant treatment costs.
A functionalized polymer developed and produced in the laboratory allows selective capture of nickel and cobalt. In this way, the impact of the presence of nickel and cobalt on industrial processes is inhibited.
Validated at the laboratory scale, the development of a prototype facility on a significant scale is currently underway. Samples are available for industrial testing and feasibility studies.
