ENPAR has been awarded a $1.13-million contract by a Canadian gold mining company for the construction and installation of a full-scale commercial ammonia treatment plant at a mine site located in northeastern Ontario. The plant should be fully operational before year-end 2009.
Ammonium-nitrate is a common form of blasting powder employed at many mining operations throughout the world. In many countries where the temperature decreases to less than 10 degrees Celsius during certain times of the year, conventional biological treatment of ammonia may not be effective. Water treatment for ammonia is important for responsible water management.
Electrochemical treatment however remains extremely effective at converting ammonia to environmentally friendly nitrogen gas at these low temperatures, and unlike the conventional approach, does not produce nitrate as a by-product. These advantages enable year round treatment and discharge of wastewater that meets environmental guidelines.
