Treatability of ninth avenue superfund site groundwater
- Dept. of the Army, Vicksburg, MS (United States)
The objective of this study was to evaluate, on a laboratory bench scale, the potential of various treatment processes to remove volatile organic compounds from a composite groundwater sample of six site observation wells. Treatment processes evaluated were activated sludge (AS) and activated sludge with powdered activated carbon (PAC) addition. The approach used for each process is delineated in the paper, and gross pollutant removals and priority pollutant concentrations are listed. The bacterial acclimation phase of the studies indicated that an inoculum from an activated sludge treatment system could be acclimated to the contaminants in the groundwater samples. Biochemical oxygen demand removals were always in excess of 95 percent. However, total organic carbon and COD removals were only in excess of 50 percent. The priority pollutants detected in activated sludge effluent were at concentrations very near their analytical detection limit. The addition of PAC to the activated sludge units improved the removal of the gross pollutants when compared to the AS bioreactors, and the percent removal increased with increased PAC dose. AS treatment augmented with the addition of PAC seemed to be more effective than the AS biological system alone for removing the gross pollutants and organic priority pollutants.
