Chlorine fate and transport in distribution systems: Experimental and modeling studies
It has become generally accepted that water quality can deteriorate in a distribution system through microbiological and chemical reactions in the bulk phase and/or at the pipe wall. The most serious aspect of water quality deterioration in a network is the loss of the disinfectant residual that can weaken the barrier against microbial contamination. Studies have suggested that one factor contributing to the loss of disinfectant residuals is the reaction between bulk‐phase disinfectants and pipe wall material. Free chlorine loss in corroded metal and polyvinyl chloride (PVC) pipes, subject to changes in velocity, was assessed during an experiment conducted under controlled conditions in a specially constructed pipe loop at the US Environmental Protection Agency's test and evaluation facility in Cincinnati, Ohio. These studies demonstrated that in older unlined metal pipes, the loss of chlorine residual increases with velocity but that wall demand in PVC was negligible.
