Discharge of domestic and industrial waste water without treating into environmentcauses hazardous effects. Therefore treatment of waste water before discharge is necessary, Sequencing Batch Reactor (SBR) is a modified activated sludge process which can be successfully used to treat municipal and industrial waste waters. The SBR process can be applied for removal of nutrients, high Biological Oxygen Demand (BOD) present in the waste water of food industries, tannery industries and landfill leachates. The present study is intended to examine the efficiency of the SBR by analyzing various parameters of the influent and effluent of sewage water and also to increase the efficiency of the SBR by inoculating nitrifying and denitrifying bacteria into the SBR. The results obtained demonstrated that the effluent water (after treatment) met the standard specifications of World Health organization (WHO) after 24 hours of treatment in the SBR. The treated water could be mainly used for gardening and other domestic usage.
