CP072  Specification, Design & Operation of Sequencing Batch Reactors Wastewater Treatment
Sequencing Batch Reactor (SBR) processes have found wide application in the water industry recently. However, the claimed advantages for effluent quality, process stability and ease of operation have not always been achieved and serious difficulties have occurred resulting in compliance problems.

Although SBR systems are variants of the activated sludge process, the design parameters are often different. This resulted in difficulties when purchasers of SBR systems were developing specifications or comparing tenders from different suppliers. This research in conjunction with two major UK water utilities developed guidelines which explained the significance of important design variables, their interaction and effect on plant performance. The guidelines also provided advice on features desirable for process stability, good sludge settleabilty and effective process control.

Benefits

  • Reduced risk of effluent quality failure from incorrectly specified processes
  • Increased number of effective process options available for asset management planning and capital programmes
  • Efficient and rapid selection of the most appropriate process for a given application internationally.
