The Electrochemical Water Treatment process solution is a highly automated process, which minimizes the need for personnel while ensuring high quality water treatment performance.

Outotec’s EWT solutions can be purchased as a process solution island with full maintenance, spare parts and operational support services. Outotec can also offer a complete water treatment solution from test work including: laboratory scale test work to on-site piloting, conceptual and feasibility studies, basic and detailed engineering, as well as developing a solution for the entire process.

Potential sources of water contamination from the mining industry include drainage from surface and underground mines, wastewaters from beneficiation, surface run-off and acid mine drainage (AMD). Outotec says its EWT solutions can handle everything from the removal of arsenic, selenium and antimony, to trace metals and organic removal. Customer specific wastewater can also be tested in Outotec's lab in Pori, Finland, to help customers find the optimal solution.

One Outotec EWT-40 module can treat approximately 5-40 m3/h of waste water depending on the application. The operation can easily be scaled up as needed simply by adding more modules. Another benefit is said to be the added value it brings to customers - the modules can be easily relocated or resold, protecting the investment beyond plant lifetime.
