Trace element removal by coprecipitation with amorphous iron oxyhydroxide: engineering evaluation. Final report

Technical Report ·
OSTI ID:5592244
; ;
Coprecipitation with iron appears to be technically and economically feasible for arsenic removal, and technically and economically feasible for selenium removal, provided selenium is predominantly in the selenite form. Furthermore, if treatment could be successfully carried out in existing ash ponds instead of conventional treatment equipment, treatment costs could be reduced to approximately $144 per million gallons (3.8 cents/cu m). 41 figs., 120 tabs.
