Removing THMs From Drinking Water Using High‐Energy Electron‐Beam Irradiation

Cooper, William J. / Cadavid, EvaMaria / Nickelsen, Michael G. / Lin, Kaijun / Kurucz, Charles N. / Waite, Thomas D.

High‐energy electron‐beam irradiation was shown to be efficient for removing trihalomethanes (THMs) from drinking water. The process was demonstrated on a 1.5‐MeV variable‐current (0–50 mA) electron‐beam system at a flow rate of 120 gpm and on a ⁶⁰Co gamma source. Of the four THMs, chloroform was the most difficult, i.e., energy‐intensive, to remove. The brominated THMs were much more efficiently destroyed by the process. Organically bound halogens were converted to halide anions, and no organic halogen or oxyhalogen reaction by‐products were observed.
