GAC for TOC Removal from Detained Stormwater
TOC has been suggested as a surrogate parameter for evaluating the effectiveness of granular activated carbon filters in removing THM precursors from potable water supplies. Adsorption of less than 10 mg/L of TOC from lake water onto Filtrasorb 400 was studied with column contacting modes. In column studies, the relationship between either normalized effluent concentrations or adsorption capacity, and the volume of water passed through the filter was found to be described by power equations. Using the best fit power equation for each column, the volume of water treated and cumulative mass loading at exhaustion were estimated. These were found to be highly dependent on the residence time of water in column, or empty bed contact time. A maximum observed adsorption capacity of 17 mg of TOC per gram of GAC was calculated from batch studies and 8 mg of TOC per gram of GAC using column studies at an empty bed contact time of 141 seconds. This removal of TOG was accomplished with minimal bacterial degradation.
