Does an unknown mechanism accelerate chemical chloramine decay in nitrifying waters?

摘要

Most chloraminated water distribution systems experience accelerated chloramine loss after the onset of severe nitrification. It is commonly believed that nitrification (largely the nitrite and pH changes induced by nitrification) is the major cause of chloramine loss. The experiments described in this article showed that nitrite and pH or other known mechanisms are not sufficient to explain the decay observed in severely nitrifying bulk waters.
