The Behavior of Polymeric Pipes in Drinking Water Distribution System—Comparison with Other Pipe Materials

The inner walls of the drinking water distribution system (DWDS) are expected to be clean ensure a safe quality water. Complex physical, chemical, and biological processes take place when comes into contact with pipe surface. This paper describes impact leaching different compounds from supply pipes subsequent risks. Among these compounds, there heavy metals. It is necessary prevent metals getting DWDS. Those susceptible impacting delivered population either by dangerous chemicals or enhancing development microorganism growth on corrosion process materials, scale formation mechanisms, bacteria formed in layers discussed. Water treatment materials also affect composition. Pipe act differently flowing stagnation conditions. Moreover, they age (e.g., metal-based subjected while polymer-based have decreased mechanical resistance) enhanced bacterial film formation. dynamic environment, therefore, models that used must consider changes occur over time. Mathematical modeling complex includes description time, correlated model for biofilm disinfectants–corrosion products disinfectants–biofilm interactions. range simple longitudinal dispersion Monte Carlo simulations 3D modeling. review helps clarify what possible sources responsible degradation. Additionally, it gives guidance measures needed maintain stable quality.
