A cost-effective electrochemical water-treatment system
Outotec
Combining its unique understanding of water treatment, process design, electrolysis and hydrometallurgy, this company has developed EWT-40 (photo) — a single modular electrochemical water treatment system. With EWT-40, purification of wastewater is based solely on electricity and the right combination of electrode materials, so there is no need for chemicals. The EWT-40 module can treat between 5 and 40 m3/h of water, depending on the application. EWT-40 can be utilized to treat a wide range of wastewaters, removing various impurities, such as: arsenic, selenium, antimony and other metals; thiocyanate; thiosulfate; phenol; and organic residues. The system is cost-effective because no chemicals are required, and treatment is faster than conventional precipitation processes. Hall B3, Stand 416 — Outotec Oy, Espoo, Finland
