Conventional sequencing batch reactors (SBRs) that utilize diffused-air networks have existed in the U.S. for about three decades now. The reliability of controls and instrumentation has significantly improved in the last 10 to 15 years, and as a result, SBR plant designs are becoming more widely accepted. The attractiveness of their compact layout and ease of operation has also helped increase their popularity.

SBR savings

Perry Township in Fayette County, Pa., is one of the first SBR plants to be designed around a layout that utilizes a surface-mounted process aerator/mixer. This aerator is a significant improve- ment over the traditional diffused-air network designs;The new layout offers substantial capital investment savings, operational savings and improved process flexibility.

The facilities plan developed for Perry Township recommended a continuous flow reactor design utilizing diffused air.The original design engineer for the project looked at a variety of manufacturers and eventually selected an SBR system proposed by Wagner Fluid Systems out of Winficld, Pa.,—a process equipment supplier with an established history of successful SBR designs.
