Abstract

One of the parameter that could reason to decrease water quality in distribution system is velocity change in networks. This study is to analyze the effects velocity changes on the water quality in water distribution systems. We need to choose different locations that will be water quality and quantity relative too much. Location of the study has been in Ahwaz of Iran. There are two instances for the conduct of this analysis, local environment and Laboratory condition and this analysis had been done independently as far as the plants are concerned. The results showed that the distance travelled and residence time have been causing to increase bacterial growth (HPC), hydraulic change in water distribution system in Ahwaz so, velocity has a reversed relationship with bacterial growth (HPC). Velocity change has been causing to increase bacterial growth (HPC) so change Velocity has a direct relationship with residual chlorine. Velocity change has been causing to increase chlorine consumption more. Also, Kw hasn’t any relationship with change velocity and bacterial growth (HPC) and change Velocity has a direct relationship with turbidity with the aid of the diagrams and Figures, the results of station sampling in the water distribution systems of Ahwaz have shown that the systems have large transmission line and have extensive networks.
