Radium Reduction Methods and How They Affect your Residuals - Some are "Hotter" than Others

New IEMA DNS regulation controls radium residual discharges from both water and wastewater treatment facilities. This includes water treatment residuals disposal in landfills and wastewater treatment residuals disposed by land application and landfills. The residuals created by potable water treatment plants for barium and/or radium vary dramatically by the treatment process. Some processes present a greater issue with disposal than others. This presentation will discuss the most commonly used radium removal methods and how they can affect disposal of residuals.
