At many water treatment facilities, water being treated by an oxidant is exposed to direct sunlight. The ready decomposition of both ClO2 and ClO2(1-) by sunlight and fluorescent lights can lead to significant losses during water treatment. The characteristics of the water plays an important role in the nature of the byproducts resulting from light-initiated reactions, and significant levels of ClO3(1-), BrO3(1-), and bromoform can be produced. The bromide ion was found to play a particularly important role in THM formation and in initiating light reactions that accelerated the decomposition of ClO2 in the dark.
