Abstract
Water contaminated with a trihalocarbon is passed through a first or second bed containing particles of an activated composite adsorbent comprising alumina and zeolite. The trihalocarbon is adsorbed onto the particles, thereby reducing trihalocarbon concentration in the water. The adsorbed trihalocarbon is reacted with air or steam at an elevated temperature in order to regenerate the adsorbent particles for reuse. Gaseous HCl produced in the reaction with air or steam may be adsorbed in a third bed containing adsorbent agglomerates.
