Two methods for removal of Radon from drinking water are considered: activated carbon adsorption and packed tower aeration. Although both granular activated carbon (GAC) and packed tower aeration have been identified as the most effective technologies for the removal of radon from drinking water, the long EBCTs required for removing radon by GAC results in substantially greater production costs than are required for packed tower aeration. Therefore, based upon the facility requirements and costs it would appear that packed tower aeration will become the most viable treatment alternative.
