Full Description

This powerpoint presentation outlines a study to develop a technology to remove andeliminate perchlorate from contaminated water. Specific objectives were to: investigate the adsorption and desorptioncharacteristics of perchlorate on granular activated carbon (GAC);to check the various operational conditions by batch(isotherm) and column studies, with the goal of usingthe smallest amount of regenerant to recover thehighest amount of perchlorate; and,to chemically reduce perchlorate into harmlesschloride. Process overview included: perchlorate adsorption on GAC; perchlorate desorption using NaBHsub4/sub as regenerant; and,perchlorate destruction using in-situ produced nano-size iron particles. Parameters for desorption studies of perchlorate using NaBHsub4/sub are given, along with the pilot set up in an Escondido, California, facility.
