Radium Removal From Hungerford & Terry
Radium Removal with Ferrosand®
Radium, like arsenic, is increasingly prevalent throughout well water sources. And like arsenic, most applications are readily treatable using the Ferrosand, or Manganese Greensand filtration process. The principal of the treatment process is to complex the radium with manganese and remove the two constituents together. The process capitalizes on the need to treat for manganese where manganese is naturally occurring and is above the MCL of 0.05 mg/L. Waters that do not have manganese naturally occurring, or have insufficient manganese for effective radium removal can be easily treated by introducing manganese as a chemical additive. The radium, once bound to the manganese, is removed from the filter with the backwash. The waste is typically acceptable to the local sewer authority for disposal.
Ion exchange is an alternative method of treatment. Ion exchange for radium removal is generally more costly when the capital, operating, and waste disposal costs are compared to that of a simple filtration process. Ion exchange is better suited for applications where softening is required and the radium limit can be met after blending. The overall treatment requirements of a given water source determines the best method of treatment.
