Investigations on drinking water in contact with PE-RT materials [PERT]


Plastic Pipes Conference Association # 2012 Barcelona

Amaia Bastero

Drinking water needs to be healthy, clean and tasteless and its quality at the tap is determined by microbiological, chemical and organoleptic parameters. Currently in Europe, the compliance with the national drinking water regulations is required and the absence of a harmonized European regulation generates intense debates in the marketplace regarding the best suited materials for drinking water pipes. The inherent microstructure of DOWLEXTM PE-RT materials ensures the temperature resistance required by the hot & cold water pipe applications without the need of chemical post-modification of the material. The absence of added chemical compounds which can migrate to water ensures a low level of taste and odour of the water exposed to the pipes, complying with current regulations. Taste and odour investigations are conducted internally and externally to ensure the inertness of our materials to the water organoleptics. The combined efforts of a large trained human sensory panel and our electronic capabilities allow us to ensure fast, statistically significant and reproducible results.

The effect of chlorinated water environment to plastic pipes has been intensively investigated in recent years and proved to affect the lifetime of plastic pipes. Since it is known that the use of the different disinfectants (ClO2, HClO/ClO- ) imply different degradation rates, understanding the conditions...

To maintain the high quality of potable water chlorine based disinfectants are frequently dosed into the drinking water network. Considering the oxidative nature of these species their long-term impact on the aging of polyolefin pipes is a matter of interest. In this study four polyolefin pipe grades were objected to...
