Abstract | A 9.0 ppb solution of dieldrin in water was passed through a granular-activated carbon bed at the rate of 4 gpm/sq. ft. The performance of the carbon was monitored from sampling ports at bed depths of 2-1/4 and 8-1/4 inches. Isotherm tests were also run with a 9.0 ppb dieldrin solution. The isothermal results were subjected to treatment by the Michaels Method of mass-transfer analysis and compared with the experimental column performance. The granular-activated carbon bed was found to be capable of removing essentially 100 percent of the dieldrin from solution. The column life, though dependent on the system variables was found to be excellent. In this test, with a carbon bed 8 1/4 inches deep, the percolation bed was found to be capable of treating 170,000 gallons of solution per cubic foot of carbon before an effluent concentration of 0.1 ppb was exceeded. Comparison of experimental and theoretical break-through curves indicated that this system is amenable to analysis by the Michaels Method. The isotherm followed the Langmuir model quite closely indicating monomolecular deposition of dieldrin on the carbon. |
