The Effects of Manganese-Reducing Bacteria on Desorption of Manganese from MnOx(s) Coated Media
… that Mn-reducing bacteria on the filter media play a substantial role in this phenomenon. The primary goal of this research was to assess the role of Mn-reducing microorganisms in the desorption of MnOx(s) from coated filters once pre-filtration chlorine ceased. A secondary objective …

Biogeochemical Cycling of Manganese in Drinking Water Systems
… selective Mn-oxidizing and -reducing culture media. 16S rRNA gene sequencing revealed that most are bacteria of the Bacillus spp. (i.e., Bacillus pumilus and Bacillus cereus). These bacteria are capable of performing Mn-oxidation and -reduction under controlled laboratory conditions. …

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 …

A Pilot-scale Evaluation of Soluble Manganese Removal Using Pyrolucite Media in a High-Rate Adsorptive Contactor
… by Zuravnsky (2007) focused on the use of oxide-coated media in a post-filtration contactor and served as a starting point for the research reported in this thesis. As a part of the work conducted by Zuravnsky (2007), a preliminary model was formulated to predict soluble Mn removal via adsorption …
