Abstract

This study presents a framework for pressure transient simulation as well as local wall shear stress analysis to manage biofilm growth in water distribution systems. The study aims to disrupt the growth of biofilm colonies attached to the inner walls of pipeline systems. In this approach, the examined systems are subjected to consecutive controlled pressure transient waves. The transient waves are originated by causing sudden changes via valves' manipulation in the distribution system. It is vital to keep the head pressure confined between the allowed pressure range to ensure the integrity of the system. The transient simulation is done by the Lagrangian-based wave characteristic method transient analysis model; two example applications are explored demonstrating the potential of the suggested approach.
