We are currently scaling up and nuclearising a patented electrochemical process for removing chloride and organics (i.e ETDA, formic acid) from spent decontamination solutions generated during nuclear decommissioning operations. Other technologies we have indentifed as offering potential cost savings during decommissioning are electro-pickling of steel, microwave concrete scabbling and ohmic/microwave heating of liquid and solid waste streams.

Our collaberation with the National Nuclear Laboratory on the ELENDES (Electrochemical Enhancement of Nuclear Decontamination Solutions) project has demonstrated via active trails the effectivness of an electrochemical process in removing chloride (sub 10ppm) and destroying 100% of the complexing ability of EDTA in 1L batches of acidic spent decontamination solutions.

The process hardware is currently been scaled up to allow us to conduct active trails at the 10L scale and an outline design for a 480L version has already been generated. C-Tech are keen to replicate the sucess of the ELENDES project and work with companies in the nuclear sector to develop nuclearised versions of our technologies to meet specific decomisioning/decontamination challenges.

Key benefits of electrodialysis

  • Reduce waste disposal costs by recycling
  • Improve product purity by removing salt
  • Converts salt product to free acid or base
  • Improve volume efficiency by decreasing product inhibition
  • Can be applied in situ, as well as downstream processing

Electrodialysis Applications


Electrochemical enhancement of fermentative succinic acid production to reduce costs and improve efficiency.


Utilisation of electrodialysis (ED) membranes for the recovery of amino acids from enzymatic reaction mixtures.
