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.
