This paper investigates the treatment of brines using zeolites synthesized from fly ash derivatives. Zeolite P was synthesized hydrothermally from fly ash or fly ash derivatives. The removal of elements from the brine using the fly ash derivatives are compared to fly ash and commercial zeolite Y. It was found that the zeolite P synthesized from fly ash derivates had a greater removal of the major elements (ie. Ca, Mg) than the commercial zeolite Y. In terms of the removal of the minor elements (ie. Al, V, Be, Cr, As, Fe, Mn, Zn, Co and Se), zeolite P was found to correspond to that of fly ash and commercial zeolite Y.
