Review of SBR process in effluent treatment

Abstract

SBR process evolved from activated sludge process. Because the long cultivation period of activated sludge process and the treatment effect can not meet the needs of production and life, SBR process and related variant improved process came into being. Since the 21st century, with the development of automatic control technology, SBR process has become a widely used technology. This paper introduces the SBR technology and the related improvement process, and puts forward suggestions for the development of SBR Technology in the field of sewage treatment.

Energy, Performance, and Reliability Analysis of Wastewater Treatment Plants in Small Communities in Ontario

“…The organic matter degradation law in the SBR process is identical to that in a push flow aeration tank. The SBR response tank is push flow in the sense of time, while the push flow aeration tank is push flow in space (length) (Jing, Wei-li, and Fu-chuan 2021). The initial concentration of organic matter in the tank is high because to the progressive transformation of organic matter in the SBR process.…”

“…The idle period may or may not be set. The SBR process has distinct advantages over conventional effluent treatment systems (Jing, Wei-li, and Fu-chuan 2021). SBR tank is appropriate for automatic control system, which can alter the reaction time according to the influent water quality and quantity; the process makes full use of and meets the basic principles of biological reaction process and unit operation; the process is simple and cost-effective.…”

A life cycle approach to environmental assessment of wastewater and sludge treatment processes

“…SBR is a sewage treatment technology that is still under development and the appropriate management platform and management mode must be updated and enhanced regularly. The disadvantage of conventional SBR technology includes an extended treatment cycle, frequent switching of inlet and outlet water, high needs for equipment automation, high amount of energy and considerable water level changes (Jing et al, 2021). SBR has very high removal efficiencies up to 90%-95% for BOD, 90%-96% for COD, 92%-97% for TSS, 80%-90% for ammonia and 80%-90% for nitrogen and phosphorus (Khalil et al, 2008;.…”
