SBR is very widely applied internationally using various types of as a technology can be explored more in India on high strength
decanters, types of SBR and applications. SBR has been applied to wastewaters for removing pollutants from complex natured
different kinds of wastewater like a tannery, textile, and chemical wastewater as future scope of research. There is a critical need for
treatment as well as for sewage application. Most of the SBRs the industry to take up the patented work on SBR and implement

aerators, fixed aerators, and mechanical weir operated decanters References:
