Abstract
A fluid purification system is provided for contaminated fluids such as air ontaminated with a wide spectrum of chemical warfare agents which includes two adsorption chambers with adsorption medium suitable for effectively removing chemical warfare agents from a stream of air; a valve selection device adapted for directing a stream of contaminated air to one or the other of the adsorption chambers, for directing a stream of contaminant-free air from the adsorption chamber, for directing a stream of regeneration fluid to one or the other adsorption chambers requiring regeneration and for directing a fluid stream with a concentration of contaminants from a regenerated adsorption chamber; a fluid stream diverter device adapted for diverting a portion of contaminant-free fluid from one or the other adsorption chambers for use as a regeneration fluid stream for regeneration of the adsorption medium in one or the other adsorption chambers; and a temperature regulation device for heating the regeneration fluid stream to a temperature effective for regeneration of the adsorption medium in the adsorption chambers.
