This powerpoint presentation outlines a study to characterize full-scale oxide coated filter media; optimize Mn removal from surface drinking water sources by oxide coated media; and, assess impact of pre-filter chlorination strategy. Media characterization of metals in coating, other metals on oxide-coated filter media; media characterization of BET surface area, Mn uptake capability; dual media Mn uptake profile; effects of water quality and operational variables on Mn uptake; effects of different parameters on Mn adsorption; intermittent media regeneration; effect of pre-filter chlorination on disinfection byproducts (DBPs); and, adsorptive contactor characteristics.
