Pipe Material Influence On Variable Formation Of Chlorine Disinfection By-Products In Water Supply Networks

Abstract

Well-known, prominent two-chlorination disinfectant byproducts (DBPs), i.e., Trihalomethanes (THMs) and Trihaloacetic Acids (THAAs), emerge in drinking water when reacting with other constituents in water. The chlorination of water nowadays crucial step in water supply infrastructure, yet the production of chlorine-generated DBPs has emerged as a critical public health issue. The pipe nature used for water supply is considered an important factor for the manipulation in the production of Chlorine DBPs. This study validates the pipe nature effect in the production of Chlorine DBPs by using the two types of pipe, i.e., Galvanized Iron (G.I.) and High-Density Polythene (HDPE). When the chlorinated water comes in contact with the surface of two different nature pipes, fluctuating results were seen.  These findings certainly contribute to the contrast between the generation of prominent DBPs formation under the known two supply mediums. Overall results from this study revealed that the G.I pipe nature contributes more to the chlorine DBPs production as compared to the HDPE pipe nature.
