•Case Study: City of Pewaukee, Wisconsin
This radium removal pilot study was conducted for the City of Pewaukee, Wisconsin. The raw water source for this pilot study was taken prior to any treatment, or the addition of any chemicals, and therefore operated only when the well was operating. Water from the well is treated with sodium phosphate and chlorine before it enters the distribution system. Naturally occurring radionuclides in the City of Pewaukee's raw water source exceed current Maximum Contaminant Levels (MCL's) for combined radium and gross alpha.
The City of Pewaukee selected Water Remediation Technology's (WRT) Z-88™ Radium Removal Process as a possible cost effective solution for their radium and gross alpha problem. WRT provided a one GPM (gallons per minute) pilot plant, which was delivered and installed on April 19, 2005.
The purpose of this pilot study is to demonstrate the effectiveness of the treatment process on this water, establish design parameters for the full scale system and meet regulatory piloting requirements.
The pilot unit has successfully reduced combined radium and gross alpha and met radium and gross alpha compliance at all times during the pilot study. Based on the data received at the time this report was written, the pilot plant had been in operation for 49 days and effectively reduced the level of radium to less than the MCL.
