Title: Biological process for manganese control in water supplies
Project Type: Research
Start Date: 3/01/2010
End Date: 2/28/2011
Congressional District: KY Sixth
Focus Categories: Treatment, Water Quality, Methods
Keywords: humic acid, manganese-oxidizing bacteria, biological filter
Principal Investigator: Wang, Yi-Tin
Federal Funds: $ 5,000
Non-Federal Matching Funds: $ 17,302
Abstract: This research proposes to implement a catalytic and cell immobilization process utilizing Mn(III, IV) oxide coated sand in batch and continuous flow laboratory studies to evaluate the capability of Mn(II)-oxidizing bacteria to utilize the oxidation products of humic acid and remove/control Mn(II). The results of the proposed study could potentially serve as the basis for an innovative drinking water treatment process for the removal/control of both manganese and natural organic matter. Such a system could also eliminate the frequent need to replace or regenerate adsorbents (such as granular activated carbon), or use of a chemical oxidants to regenerate manganese greensand.
