This slide presentation outlines a study on manganese removal by oxide coatings that focused on media characterization and optimization of operational variables. Overall research objectives included: characterize the oxide coated media for Size and surface area, and Oxide coating level; conduct laboratory experiments for Mn uptake capacity, and examine the impact of operational variables on Mn removal; evaluate laboratory and full scale media regeneration requirements for both online and offline use of oxidants; and, guidance and documentation. Laboratory experiments included: extraction of metal oxide coatings on media (Mn, Al, Fe, Cu, Ca); Mn uptake capacity: compare media collected from different plants; and, column experiments: Impact of operational variables on Mn+2 removal. Includes figures.
