Full Description

Biological and chemical reduction processes, membrane processes, and ion exchange were investigated in this study for perchlorate removal via ion exchange and chemical reduction. The focus of this research is the biological reduction of perchlorate. Reduction processes are based on the fact that percholorate is thermodynamically unstable. The three primary objectives of this research were: to establish the ion-exchange capacity of Norit GAC for perchlorate; to establish that perchlorate at low : g/L concentrations can be biologically removed to below the limit of detection (2.0 : g/L) using biologically active carbon (BAC) filtration; and, to determine a correlation between nitrate concentration and level of perchlorate removal. Includes 7 references, table.
