To mitigate the impact of mining operations on a local wetland, a Western US mine must collect and treat a selenium contaminated groundwater stream prior to discharge.
To deliver environmental compliance without a large footprint or construction effort, Frontier Water Systems supplied a modular SeHAWK® bioreactor along with auxiliary plant equipment, housed inside a 2000 sq. ft tent structure. Commissioned in 2015, the selenium treatment plant has operated continuously by Frontier Water field engineer staff to maintain high rate selenium reduction to >95% removal.
