| Abstract |
Powdered activated carbon (PAC) and granular activated carbon (GAC) were evaluated for a chlorite and chlorate control. From our batch experiments it showed that the reaction between chlorite and activated carbon yields chloride as end-product. The removal of chlorite depended on the initial concentrations of chlorite, the activated carbon dose, pH and the activated carbon used. Filtration of water containing chlorite and chlorate through beds of GAC was found to remove chlorite and chlorate. GAC effectively removed chlorite, but, depending on the contact time and pH. The removal of chlorite appears to be a result of chemical reduction. Removal of above 90% of chlorite was achieved at elution rate of below 60mL/min. No chlorinated species other than chloride were detected. |
