This project was undertaken to study produced water treatment using Sequencing Batch Reactor (SBR). The treatment involves both untreated produced water and anaerobic treatment effluent of the produced water. Produced water is the water extracted along with oil and gas. Different physical and chemical methods have been used for its treatment~ but their initial and/or running cost are high and produce hazardous sludge. Biological treatment of oily wastewater can be a cost-effective and Eco-friendly method for produced water treatment to comply with discharge limits. The objectives of this project are to apply an aerobic treatment process using bacteria for hydrocarbons and organic matters removal and to compare the effluent quality of an aerobically treated produced water and anaerobically treated effluent followed by aerobic treatment. Therefore project scope is to apply the treatment is applied in to meet discharge limits according to standard B. To treat produced water biologically; aerobically and anaerobically treated effluent followed by aerobically treatment. while studying different biological parameters. Project methodology started with Research and data gathering for produced water, biological treatment and SBR. followed by Sampling from TERENGGANU CRUDE OIL TERMINAL (TCOT). Sludge acclimatization was then applied by diluting produced water into domestic wastewater source of the biomass Produced water characterization. Sequencing Batch Reactor (SBR) was then configured and operated using five phases cycle fill. react. settle. decant and idle. The result showed that the removal efficiency of 73.8% and 82%, BOD removal efficiency is 61.8%, 59.8%. Oil and Grease removal efficiency is 72.5%, 81.25% for anaerobically treated effluent and produced water respectively iv
