An Introduction to Vacuum Sewerage System and its Applications in China

Abstract

Vacuum sewerage system (VSS) is an ecological wastewater collection system in which negative pressure difference in pipelines is used to transport sewage gradually to vacuum station for centralized treatment. Classification and application areas of VSSs were reviewed. Various vacuum generators in vacuum stations were compared. Types and key technologies of user terminals in VSSs were presented. Conveying mechanism of vacuum pipelines was illustrated. The way to discharge sewage from VSSs was introduced.

Maintenance issues of the vacuum sewer system

“…Concepts of vacuum sewer system appeared already by the end of the 19th century (Tang et al 2013), when technological developments allowed engineers to construct devices to pump sewage (Miszta-Kruk 2016). It is not entirely clear who can be named the inventor of vacuum sewer system and exact year of invention.…”

Reliability and failure rate analysis of pressure, vacuum and gravity sewer systems based on operating data

“…Relevant proposals can be found in the following publications: [2,4,[11][12][13][14][15]3,6,10]. The methods proposed in the last three texts are used in practice to assess reliability of different network systems in Poland.…”
