flow periods to save power. Because the mixers and aerators remain off, this scenario has an energy-savings component. Mixed Fill – Under a mixed-fill scenario, mechanical mixers are active, but the aerators remain off. The mixing action produces a uniform blend of influent Sequencing Batch Reactor Design and Operational Considerations 4

www.neiwpcc.orgSBRs 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. According to a 1999 U.S. EPA report, an SBR is no more than an activated-sludge plant that operates in ...
