This powerpoint presentation outlines a study to develop a technology to remove and
eliminate perchlorate from contaminated water. Specific objectives were to: investigate the adsorption and desorption
characteristics of perchlorate on granular activated carbon (GAC);
to check the various operational conditions by batch
(isotherm) and column studies, with the goal of using
the smallest amount of regenerant to recover the
highest amount of perchlorate; and,
to chemically reduce perchlorate into harmless
chloride. Process overview included:
perchlorate adsorption on GAC; perchlorate desorption using NaBH<sub>4</sub> as regenerant; and,
perchlorate destruction using in-situ produced nano-size iron particles. Parameters for desorption studies of perchlorate using NaBH<sub>4</sub> are given, along with the pilot set up in an Escondido, California, facility.
