Sequencing batch reactor or sbr is a new technology for the treatment of domestic and industrial waste water. It is ideal for treatment of wide range of domestic and industrial waste water at flow ranging from few thousand liters to millions of liters per day. The sbr process treats wastewater by activated sludge process.
The Sequencing Batch Reactor (SBR) is an activated sludge process designed to operate under non-steady state conditions. An SBR operates in a true batch mode with aeration and sludge settlement both occurring in the same tank. The major differences between SBR and conventional continuous-flow, activated sludge system is that the SBR tank carries out the functions of equalization aeration and sedimentation in a time sequence rather than in the conventional space sequence of continuous-flow systems. In addition, the SBR system can be designed with the ability to treat a wide range of influent volumes whereas the continuous system is based upon a fixed influent flowrate. Thus, there is a degree of flexibility associated with working in a time rather than in a space sequence. |
