Numerical Analysis of Sediment Transport in Sewer Pipe

The efficiency and economical performance of sewer systems is an essential issue in urban drainage. The need for sewers to carry sediment has been recognized for many years. One of the main problems in designing sewerage systems is the sediment deposition. Sedimentation in sewers occurs regularly according to the alternating natural flow. The present study investigates the hydraulic characteris...

Automated Sewer Pipe Inspection through Image Processing

An innovative inspection method to assess the condition of sewer pipes is proposed in this paper. The standard sewer inspection technique, based on closed-circuit television systems, has a very poor performance. A video camera is mounted on a robot and the video recording is provided off-line to an engineer that classifies the potential defects. The focus of the research is the automated identi...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Life Cycle Assessment of Sewer System: Comparison of Pipe Materials

Sewer system is fundamental urban infrastructure for the public sanitation. Construction of sewer system is needed to invest a huge amount of capitals and labours as well as generates various and wastes and atmospheric emissions, and hence sewer pipes should be appropriately managed in the environemental aspect which is analysis of greenhousegases(GHGs) emissions. In this study, we investigated...
