Costly advanced water treatment methods are necessary to meet the standards for the disposal of oil products polluted waters to commercial fishing water bodies. The objective of the present research is establishing the efficiency of gas-phase pulsed corona discharge applied to oil products removal dependent on treatment parameters. The results showed the ability to cost-efficiently purify the produced water to the standard requirements; the maximum efficiency treatment parameters were determined. The mass transfer of oil products was determined to limit the overall process rate. The treatment method efficiency was confirmed in pilot-scale experiments.
