Abstract

Abstract Nitrification-driven chloramine decay kinetics have largely been unquantified in premise plumbing, which is particularly vulnerable to opportunistic pathogen growth. Here, we carried out complementary experiments in an at-scale premise plumbing rig with mature biofilms (>4 years age) with influent residuals of 0.9). The best fit chloramine decay reaction order varied among the rig pipes from 0.88 to 2.74, depending on chloramine dose and exposure time, hydraulics, and modeling method.
