Model Development for Residual Chlorine

open access: yesJournal of Engineering Research and Reports, 2023
The research is to develop a mathematical model for the decay of residual chlorine at the nodes and compare with results from Epanet 2.0. All the influencing parameters of initial chlorine Ccl(init(o)), bulk decay (Kb), wall decay (KW) and travel time (t), were well represented and the equation is developed applying the differential form of the first ...

Laboratory and pilot plant scale study on water dechlorination by medium pressure ultraviolet (UV) radiation

open access: yesMATEC Web of Conferences, 2017
Ultra violet (UV) dechlorination was performed to eliminate residual chlorine as the byproducts of chlorination process. UV dechlorination utilizes photon energy generated by medium pressure (MP) UV lamp to produce powerful hydroxyls which in return ...
