ABSTRACT
A series of studies by E. B. O'Neill, R. P. Wallace, and J. L. Burr, showed that it is possible to use a packed column to remove manganese from reservoir waters and mine drainage. A pilot scale treatment system could be designed and installed in the field for manganese treatment of certain mining wastewaters. Three columns packed with different media were used for these studies and their efficiency of manganese removal was measured during upflow operation. The three columns were prepared as follows: Column A-Glass marble packing in a four-foot clear plexiglas four-inch diameter column. Column B-Sandstone packing in a four-foot column of four-inch diameter PVC pipe packed with sandstone which was collected in the field near Flat Rock, Alabama. Column C-Chert packing in a six-foot column of four-inch diameter PVC pipe packed with stones taken downstream from Normandy Dam, Tennessee.
