PIPE SECTION REACTOR TO EVALUATE CHLORINE-WALL REACTION

Development of a bench-scale, pipe section reactor (PSR), and test measures of chlorine rate decay at the pipe wall. Description of a more convenient system than pipe loop reactors. The design allows investigation of the effect of velocity on chlorine–wall reaction. In addition to water velocity, the effects of water quality (corrosion rate, dissolved oxygen [DO], and pH) on the chlorine–wall reaction were also evaluated. The Cl2 decay rate was described by zero-order kinetics for cast-iron pipe, and first-order for the ductile-iron pipe section.
