| Summary: | Produced water (PW) is wastewater generated when oil or gas is extracted from underground reservoirs.
It is a mixture of various organic and inorganic compounds, including benzene, toluene, ethylbenzene and
xylene (BTEX) which has become a global environmental problem due to its enormous volume and
toxicity. The objective of this study was to investigate the feasibility of membrane capacitive deionization
(MCDI) in removing ions and BTEX components from produced water. The desalination process was
obtained when cell potential in the range of 1–1.6 V and flowrate in the range 20-40 mL/min were
applied. The system succeed to reduce ions 40.7-58.7% and organic carbon 14.2-20.1%, while the
maximum energy consumption is 0.595 kWh/m3 and the minimum energy consumption is 0.18 kWh/m3.
The research findings derived from this study identified parameters that merit further improvements
regarding modification of electrodes, ion exchange membranes, MCDI cell design to overcome
limitations of ion and organic adsorption and to overcome organic fouling.
