Study on the treatability of the petroleum refinery effluent wastewater was conducted using bench scale biological sequencing batch reactor systems. Six sequencing batch reactors (SBR) each of 2L liquid volume were operated at a 24 hours cycle. The SBRs were operated in various anaerobically stirred and aerobic modes. The average COD removals percentages for the aerobic reactor, combined anaerobic-aerobic reactors and aerobic mixed with domestic wastewater were found to be approximately, 91, 91, and 88 respectively, with its final average effluent COD of 63 mg/L, 65 mg/L, and 44 mg/L, respectively. © 2011 WIT Press. date: 2011 publisher: WITPress official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84865538115&doi=10.2495%2fWRM110621&partnerID=40&md5=e77e0cd87ad242930a8d1f8e06d79056 id_number: 10.2495/WRM110621 full_text_status: none publication: WIT Transactions on Ecology and the Environment volume: 145 place_of_pub: Riverside, CA pagerange: 691-699 refereed: TRUE isbn: 9781845645144 issn: 17433541 citation: Kutty, S.R.M. and Gasim, H.A. and Khamaruddin, P.F. and Malakahmad, A.
