Sequencing Bath Reactors (SBR)
Sequencing Batch Reactors (SBR) are a variation of the activated-sludge process. They differ from activated-sludge plants because they combine all of the treatment steps and processes into a single basin, or tank, whereas conventional facilities rely on multiple basins.
The operation of an SBR is based on a Fill-and-Draw principle, which consists of five steps—Fill, React, Settle, Decant, and Idle. These steps can be altered for different operational applications
