Investigation of Organic Compounds Migration from Polymeric Pipes into Drinking Water under Long Retention Times

AbstractUnplasticized polyvinyl chloride pipes (uPVC), Polypropylene random pipes (PPR) and Polyethylene pipes (PE) for drinking water were tested with respect to migration of total organic carbon (TOC) into water. The investigation was carried out under different long retention times aiming to investigate TOC migration trends of different polymeric pipes over time and the corresponding water quality changes like chlorine decay. Experiment results showed TOC release from all pipes increased significantly over time. PE pipe showed the highest TOC concentrations among all tested pipe materials in this study. Chlorine consumption data observed in this research followed the shape of TOC values
