The report describes a program to characterize the performance of a granular activated carbonion exchange GACIE pilot plant system for removing pollutants from the various wastewaters of a nitroguanidine NQ production plant. This program was carried out at the Sunflower Ammunition Plant, DeSoto, Kansas, from January through May 1986. It was found that carbon beds can efficiently remove NQ from any of the wastewaters tested, that cation exchange beds can efficiently remove guanidinium Gu and ammonia-nitrogen NH3-N ions, and that anion exchange beds can efficiently remove nitrate-nitrogen NO3-N ions, and sulfate SO4 ions. The amount of wastewater which can be treated before these pollutants sulfate SO4 ions. The amount of wastewater which can be treated before these pollutants break through a given bed has been ascertained, and depends on the concentration of each pollutant and a competing materials Na, Ca, Fe, and H ions in the case of cation exchange, and C1 and Oh ions in the case of anion exchange. The amount of regenerant required to reactivate the ion exchange material was also determined. Used carbon was assumed to be disposed of without regeneration. It should be noted that this process does not destroy any of the pollutants mentioned, but merely concentrates them into smaller volumes for ultimate disposal.
