Abstract
A water purifying system including two or more stages for removing organic and inorganic contaminants from source water. The system may be configured such that water is first passed through a biocidal resin, and then through a granular metal alloy and an activated carbon filter to remove iodides released into the water by the biocidal resin. The granular metal alloy may be agitated by turbulent motion as the water treated.
