REMOVAL OF CHEMICAL WARFARE AGENTS FROM WATER BY VAPOR COMPRESSION DISTILLATION

摘要

To determine whether a U.S. Army vapor compression distillation unit could prude an acceptable distillate from fresh and saline water contaminated with seven CW agents (incapacitating agent, BZ;nerve gases, GA, GB, and VX;blood gas, AC;and vesicants, HD and HN-3)nThe Army’s vapor compression distillation unit does not produce an acceptable distillate from fresh water contaminated with BZ, VX, AC, GB, or GA.nMixed-bed ion exchange resin, containing a strongly acidic cation resin and a strongly basic anion resin, is effective for posttreatment of distillate containing all the CW agents studied.nA small scale batch coagulation process involving super hypochlorination, activated carbon dehypochlorination, coagulation, and filtration is capable of effectively removing VX from a contaminated fresh water source.
