Project duration: 1 January 2017 – 31 March 2019

Objective

The aim of the EWT-CYNCOR is to upscale electrochemical cyanide and nitrogen removal process to TRL 7 a prototype to demonstrate a solution process that enables sustainable, flexible and cost-efficient polishing treatment of cyanide and nitrogen-containing process- and/or wastewaters within an operational environment.

This involves removing impurities from the process- and wastewaters enabling water recycling, decreasing environmental pollution, producing less solid waste than conventional water treatment options, and increasing sustainability and resource efficiency due to modularised, digitalised and removable water treatment process.

The solution (technology)

EWT-CYNCOR will develop polishing electrochemical treatment application for waters containing cyanide and/or nitrogen compounds. Technology will be demonstrated via laboratory scale tests (TRL5 to TRL 6) optimizing different operational parameters using real process and/or wastewater samples from mines and industry. Then, the treatment method will be upscaled to demonstrate the system prototype OT’s EWT-40 on-site (TRL 6 to TRL 7). Comprehensive treatment process will be developed testing also suitable S/L-separation technologies. The process is producing a low amount of solid product, of which stability and disposal/utilization will be evaluated. As the prototype EWT-40 can be directly up-scaled to industrial level due to the modularized solution, electrochemical water treatment process for cyanide and nitrogen compounds removal can be easily commercialized directly after the end of the EWT-CYNCOR project.

The solution proposed enables economically viable and sustainable water treatment process especially for mining and metal industry, securing raw materials supply. It is also digitalized solution collecting measurement data providing better monitoring, raw material management and efficient product service system providing new systemic ways of designing solutions. Proposed solution also enables water recycling and diminishing produced waste material that needs to be disposed aiming to close material loops.
