Selenium Treatment Services
Marshall Miller & Associates has researched, developed, and implemented an actively managed semi-passive biochemical reactor technology for remediating selenium-impacted waters associated with mining. This effort has resulted in the development of a reliable treatment technology with a significant reduction in cost over traditional systems.
160 Weeks of Demonstration Testing have resulted in
establishing system design parameters for:
-
Optimum loading rates
-
Selenium removal rates
-
Systems construction
-
Operational costs and performance
And, completing:
-
Hydrologic and chemistry evaluations (to determine design flow rates and concentrations) on over 20 square miles of surface-mined areas
-
Designs on forty five (45) systems with flow rates of 50 to 1,500 gpm (hydraulic capacity of 3,000 gpm) and selenium concentrations of 10 to 50 μg/L
-
A system design for cold climates (British Colombia, Can.)
-
System designs for both underground and surface mines
