The ability of hydrous manganese oxide (HMO)
and manganese greensand to remove radium in
order to meet the new radionuclides rule is discussed.
The authors explain how although HMO and
manganese greensand are normally used to remove the
nuisance contaminants of iron and manganese, they are
also a possible means for removing radium.
This study was undertaken to determine radium
removal in pilot- and plant-scale iron and manganese
removal plants in Brown County, Wisconsin; Knoxville and
Marcus, Iowa; Garretson and Elk Point, South Dakota; and
Lakeville, Hinckley, and Savage, Minnesota.
Water suppliers can use the information in this article
in pilot plant studies for the removal of radium by
HMO and manganese greensand filtration systems and
compare the associated costs with those of best available
technology, such as lime softening, ion exchange,
and reverse osmosis. Includes 9 references, tables, figures.
