A Midwest iron mine contains selenium-impacted waters as a result of mining operations. As a effort to ensure regulatory compliance and future mine operations, Frontier Water was selected by the customer to demonstrate treatment of the stream using a SeHAWK® Mobile bioreactor. With prefabricated construction and small footprint, the Mobile bioreactor allowed for aggressive delivery timeline and easy onsite installation of the treatment demonstration.
Throughout the project’s duration, the SeHAWK® Mobile equipment met and exceeded treatment targets for selenium as well as other contaminants, at water temperatures as low as 40°F.
