The sewer system is a very dynamic system with an abundance of mass transfer processes and transformations. A key process is the mass exchange between the wastewater and the sewer atmosphere. An equation that describes the gas-liquid mass transfer under different hydrodynamic conditions is essential when sewer processes are to be quantified or modelled.

Smart Sewer Robot to Remove Blockages in Sewer
Recent Advances in Electrical & Electronic Engineering (Formerly Recent Patents on Electrical & Electronic Engineering), 2023Background: Every system in the world is intelligent. The wastewater infrastructure is installed underground during the construction of homes and businesses. We set up lengthy, kilometers- long pipelines in the subsurface administrative architecture. However, due to the different discharges into pipelines from various sources, the pipeline typically ...

Journal of Irrigation and Drainage Engineering, 1997
Sideweirs for combined sewers in converging U-shaped channels are analyzed. The results are applicable for storm sewers. Based on extended model observations and a hydraulic approach, the characteristics of sideweir flow are determined. These include the surface profile, the discharge distribution, the end depth ratio, and the energy losses due to ...

Comparative evaluation of vacuum sewer and gravity sewer systems
International Journal of System Assurance Engineering and Management, 2016Two most common types of sewer systems are gravity sewer system and pressure sewer system. In last 25 years, a relatively new wastewater collection system called vacuum system got acceptance and popularity in certain circumstances (e.g., hilly and rocky terrains, areas with high groundwater table, unstable soil condition).
