Production of Co-Precipitated Sludge

Optimize your radioactive waste treatment processes by testing them on non-active sludges, representative of your various effluent types, reproducible, and tailor-made to meet your specific needs.

    • Test your chemical coprecipitation processes with reliable, representative sludges that mimic your waste streams
    • Optimize your treatment flow sheets before deployment on real active matrices
    • Assess the chemical stability and trapping capacity of the sludges produced
    • Guarantee the reproducibility and traceability of your production batches
    • Produce tailor-made complex sludges, adapted to your projects and representative of your waste
    • Benefit from a flexible and robust pilot unit, allowing adjustment of operating parameters to reproduce different types of sludges
    • Validate your processes by first producing small test quantities before scaling up to larger volumes
    • Ensure rigorous analytical monitoring throughout the manufacturing process to characterize the solution, the performance of sorbents, and their sorption capacity
    Implementation of a dedicated pilot
    150L of co-precipitated sludge at 300 g/L produced
    • Flexible pilot operation: variation of operating parameters to reproduce diverse sludge types
    • Stepwise production: validation on small batches before larger-scale manufacturing
    • Guaranteed reproducibility: comparable batches from one production run to another
    • Integrated specific studies: chemical stability during precipitation, sorption capacity of selected sorbents
    • Monitoring equipment: in-house analytical services for real-time solution characterization and sludge quality control
    • Proven applications: representative sludge production for the STE2 facility (five different formulations tested)
    • Robust pilot unit ensuring production continuity
    • Post-production sludge treatment: solid-liquid separation equipment (filter press, centrifugation, geomembrane, etc.)
    • Aging studies of sludges
    • Definition of operating parameters to guarantee future production under conditions representative of industrial reality
    • Production capacity: 150 L of coprecipitated sludges at 300 g/L

  • Waste Cementation: from Study to Implementation of Pilot Trials
