Day by day production of wastewater is increasing with the advent of scientific age. The direct disposal of such liquid waste in the environment ultimately upset the aquatic reservoir and human community as well. So, those wastewaters are needed to be treated before releasing in the environment. But the nature of wastewater varies significantly due to their origin. It may contain different types of organic matters, nutrients, chemicals, and heavy metals. As a result, all liquid wastewater can't be treated by following one typical treatment process. Comparing to other existing techniques SBR is a promising method to treat a wide variety of wastewater with several critical modifications. This review paper aims to find out recent works on SBR, how it has been modified to treat different types of wastewater, the efficiency of each modification in removing pollutants and other nutrients etc. This might also help others who wish to conduct research to improve the existing SBR design efficiency and discover new modifications for treating wastewater.
