Biological treatment of grey water using sequencing batch reactor Original Research Article

The aim of this study was to investigate the application of sequencing batch reactor (SBR) technology for treating grey water collected at outlet of showers room of students. The performance of SBR was satisfactory as the effluent had respectively 20 and 5 mg/L of COD and BOD. Applied two hydraulic retention times (HRTs) showed that the nitrogen and phosphorus removal could be improved while adapting to load variations.
