VALIDATION OF THE INFLUENCE OF CHLORINE DOSAGE IN LABORATORY-BASED MODEL FOR THE PRODUCTION OF CHLORINE DISINFECTANT BY-PRODUCTS IN DISTRIBUTION PIPES

Abstract

The need for safe and potable water is a basic need for every living entity and is now a global concern, necessitating an examination of the occurrence of Trihalomethanes (THMs) and Trihaloacetic acids (THAAs), two significant chlorination disinfectant byproducts (DBPs) in high-density polyethylene (HDPE) and G.I water distribution systems. This study entailed the identification and quantification of these disinfection byproducts (DBPs), thereafter addressing the occurrence of two prominent DBPs i.e. Trihaloacetic acids and Trihalomethanes in a controlled chlorine attempt in laboratory controlled prototype model. This prototype model matches and represents the original field-based water distribution network on the ground. This study sought to evaluate and compare the occurrence of chlorine DBPs considering the differences in production based on chlorine dosage and the properties of pipe materials. Gas chromatography-mass spectrometry (GC-MS(ECD)) was utilized for the study of DBP, and laboratory-based distribution models were implemented. This study provides significant insights into the dynamics of THMs and THAAs in water distribution networks, presenting strategies for minimizing these DBPs and so enhancing the objective of delivering safer drinking water in these systems.
