Secondary sedimentation in pipes theoretical derivations and field validation / Mohammad Halim Khairoji

This project deals on the cases where instead of formation of floes and sediments in the treatment plant, sedimentation occur in pipes especially in old pipes. This secondary sedimentation will decrease the cross-sectional area of the distributions pipes affecting the flow capacity. This study focuses on this phenomenon based on literature review, theoretical considerations and field trips. The aim of this study is to find out the main causes of this sedimentation in distribution pipes and to make a comparison between theoretical values and that obtained in the field.
