Current Water Technologies to deliver ammonia treatment system to Canadian mining operation

Global Mining Review,

Canadian-based company, Current Water Technologies, Inc., which is concerned with environmental protection and remediation, has received a contract to install and demonstrate its patented ammonia treatment system at an active mining site in central Canada. CWTI has successfully mobilised and demonstrated the efficacy of the AmmEL system under varying industrial site conditions, including near freezing wastewater conditions characteristic of winter months in Canada and the northern USA.

According to the company the versatile, state-of-the-art AmmEL demonstration scale unit is designed to treat approximately 100 m3 per day of mine effluent containing elevated levels of ammonia. 

The AmmEL-LC Electrochemical Ammonia Treatment System is a two-stage process consisting of ion exchange, followed by electrochemical oxidation of ammonia to environmentally friendly nitrogen gas (N2). Designed to achieve high ammonia removal rates in industrial and municipal wastewater, groundwater sources and industrial process waters, the technology does not produce nitrate, a known carcinogen, or the greenhouse gas nitrous oxide (N2O).

Unlike conventional biological systems, the technology is also not affected by low water temperatures (0°C) and has the ability to achieve very low ammonia levels (<1 mg NH4-N/L) in treated streams. The system can be implemented as a full-scale, stand-alone treatment plant for ammonia or as a complimentary upgrade to conventional methods at new and existing water treatment facilities. 

Founder and CEO of Current Water Technologies Inc., Dr. Shelp, commented: “CWTI is extremely pleased to partner with the Canadian mining industry, which is a world leader in the early adoption of cost-effective, innovative environmental waste management technologies. These mutually beneficial relationships will assist in establishing a solid platform.”
