PRODUCED WATER AEROBIC TREATMENT USING SEQUENCING BATCH REACTOR (SBR)

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
