Abstract |
The study included sampling and analysis of waters from nine municipal water treatment plants in the state of Iowa to determine the efficiency of radium-226 removal in a variety of treatment processes and to provide cost data for these processes. Supplies with a high naturally occurring radium content over 5 pCi/l in Jordan and Dakota sandstone formation well waters were selected and included four different treatment processes: reverse osmosis, iron removal filtration, sodium ion exchange, and lime-soda ash softening. Analyses were performed to determine radium, hardness, and other parameters on the well water and removals of these parameters through the treatment process. Radium-226 removals through the reverse osmosis, sodium ion exchange, and lime-soda ash softening plants were in the range of 95% removal. Radium removals in the iron removal plants ranged from 12 to 38%. |
