2. SBR (Sequencing Batch Reactor) designed by ABJ Group Sanitaire. This system is an ICEAS (Intermittent Cycle Extended Aeration System). The circuit was to provide higher quality disinfected effluent so that the reclaimed water flows to beneficial use in the South Dayton area. Currently the water flows to the Dayton valley golf course and is reused to water the grass on the fairways.
