REMOVAL OF MANGANESE FROM ACID MINE DRAINAGE
Manganese removal from acidic, low oxygen mine waters presents the greatest challenge since the kinetics, pH and oxygen concentration work against Mn removal. Neutral mine waters can also contain manganese, largely due to the extremely slow rate of Mn oxidation.

For manganese, use of the proper coagulant and flocculent can increase manganese removal in the filtration step. Also, use of a filtration media coated with manganese oxide (such as Greensand) is effective at removing manganese (and iron). Therefore, a WETS pilot study will almost always be recommended to identify the proper solution to a ...
Manganese removal physicalchemical way
Similar to iron, the manganese removal by physicalchemical way, can be carried out by the oxidation of Mn 2+ in Mn 4+, which precipitates then in manganese dioxide (MnO 2 ). The precipitation is then separated from water by filtration on sand. The only difference (with the iron), is in the reagent used. Indeed, oxidation by oxygen is in many ...
Manganese Removal from Drinking Water Sources | SpringerLink
· Removal of manganese by IX is typically only used for lower flows, often at the or building point of entry and frequently in conjunction with water softening and/or iron removal. While most ionic IX resins are made from synthetic polymers, natural minerals, some which are zeolites, such as clinoptilolite, have been studied with respect to manganese uptake capacity (, [ 49 ]).
Manganese removal by hydrogen peroxide and biofiltration ...
· Manganese was removed at pH <9, so the removal of manganese (II) on the manganese oxide surface would have involved only adsorption (Morgan and Stumm, 1964). In addition, manganese was likely synergistically removed by physical adsorption to the biogenic manganese oxides as MOB deposit oxidised manganese on their external cell surface ( Tebo et al ., 2004 ).
