Evaluation of factors affecting bulk chlorine decay kinetics for Zai water supply system in Jordan: Case Study

01.Apr.2017

​Chlorine decay behavior is significantly variable since it depends on the quality of water and the condition of distribution system. This paper describes the effect of various parameters on the bulk chlorine decay kinetics in the water samples collected from Zai water treatment plant in Jordan. These parameters are reaction time, temperature, TOC, and free chlorine dose. This work also reports the derivation of empirical formulae which describe abovementioned effects. The general trend of chlorine decay decreases with time and can fairly be represented by first-order decay kinetics. An increase in the value of temperature and TOC parameters has proportional effects on the decay of bulk chlorine. However, the data show that the decay constants were found to be inversely proportional to the initial chlorine concentration. A general correlation for the calculation of bulk chlorine decay rate constant as a function of the parameters in question of this study is proposed. Consequent predictions are in good agreement with the observed results in this study.
