A method of removing di-, tri- and tetra-valent cations from aqueous media with a relatively short residence time, by causing cations to bind to a negatively charged media immobilized on a support structure thereby incorporating the cations into or onto the structure and removing them from the aqueous media. In another aspect, the present invention relation to a structure useful for removing di-, tri- and tetra-valent cations from aqueous media. The structure is designed to facilitate adherence of cations to the structure thereby incorporating the cations into or onto the structure and removing them from the aqueous media. |
