The Role of Aluminum within MnOx(s)-Coated Filtration Media in Drinking Water Treatment
The Mn oxide (MnOx(s)) surfaces of water treatment filtration media are known to aid in the capture of dissolved Mn species, but the discovery of significant deposits of Al within these coatings raised several questions about the MnOx(s) surface. A series of experiments and analyses were performed …

The Impact of Aluminum on the Initiation and Development of MnOx(s) Coatings for Manganese Removal
… process involving manganese oxide (MnOx(s))-coated filter media and a free chlorine residual known as the natural greensand effect (NGE). In recent years, significant amounts of aluminum (Al) have been found integrated into MnOx(s) coatings on media from drinking water treatment …

Modeling Manganese Sorption and Surface Oxidation During Filtration
… soluble Mn adsorbs to manganese oxide-coated (MnOx(s)) media and is then oxidized by chlorine, forming more manganese oxide. This research builds on a previous model developed by Merkle et al. (1997) by either neglecting the empirically determined available fraction of sorption sites (referred …

Nanoscale structural/chemical characterization of manganese oxide surface layers and nanoparticles, and the associated implications for drinking water
… from drinking water by developing Mn-oxides (MnOx(s)) bearing coating layers on the surface of filter media. Multiple models have been developed to explain this Mn2+ removal process and the formation mechanism of MnOx(s) coatings. Both, experimental and theoretical studies to date have been …
