This webinar covers a general overview of groundwater treatment applications with permanganate including iron and manganese treatment with a focus on radium removal. Radium removal topics will include a discussion of the current EPA regulation along with various treatment methods that can be used like hydrous manganese oxides (HMO). The use of HMO from design of a treatment system to application rates and water quality parameters that affect removal efficiencies and the feed equipment used for these systems will be shown. Case studies from several cities showing the success of HMO for radium removal will be presented. Finally, safety and handling of permanganate and HMO solutions will be discussed.
