To optimize and find out the effect of operating conditions on the different responses for EC and EC/PS, response surface methodology (RSM) was implemented. The results showed that EC process had considerable performance in the removal of H2S (96 %), oil and grease (O&G) (98–99 %), turbidity (91–97 %), phosphate phosphors (94 %), and heavy metals (92 %). EC/PS was introduced as an effective and a compact method for the removal of soluble hydrocarbons and nitrogen-ammonium (N-NH4+). The results indicated that at the current density of 35 A/m2, PS of 30 mM, reaction time of 30 min, N-NH4+ and chemical oxygen demand (COD) removal efficiency increased to 37 % and 71–94 %, respectively. To further increase the ammonia removal, EC/PS was integrated into thermal-PS activation at 65 °C, and the results showed that the ammonia removal by thermal/EC/PS reached about 69 %. According to gas chromatography/mass spectrometry (GC/MS), EC/PS was able to effectively eliminate most of the hydrocarbons. Moreover, a new kinetic model based on a novel algorithm and the main reactions occurring during EC/PS was developed to predict the COD removal efficiency, and the results indicated that it could predict COD removal efficiency with the acceptable accuracy. The estimated operating costs and energy consumption for EC/PS demonstrated that this process was more economical and efficient than other advanced oxidation processes (AOPs).

The use of novel cleaner technologies lead to effective productions in chemical industries. The dyes involve the complex structure, recalcitrant nature, and more intermediates. The generation of oxidative species with higher yields is obtained by advanced oxidation processes as a green and powerful treatment technology. These processes are the effective, inexpensive and eco-friendly methods for decaying the toxic pollutants. The AOPs are classified as non-photochemical and photochemical processes. There are included various technologies such as ozonation, Fenton oxidation, wet air oxidation, electrochemical oxidation and photocatalytic oxidation. The production of highly reactive free radicals is the main purpose of the AOPs process. The generation of free radi...

The new trend of using natural coagulants to treat saline oily wastewater can help overcome the drawbacks of inorganic coagulants such as high costs, health risk, and large amounts of sludge. In the present study, the Lallemantia mucilage was used for the first time as a novel natural coagulant, which offered a remarkable performance in bilge water treatment at the optimum condition of coagulants dose = 10 mg/L, pH = 7.00, and contact time = 23.8 min with the maximum chemical oxygen demand (COD) removal efficiency of 87.57 % and influent COD of 1202.5 ± 8.5 mg/L. Also, at the optimum condition, Lallemantia mucilage could remove surfactant up to 20.6 % with influent concentration of 55 ± 0.4 mg/L. A quadratic polynomial with R2 = 0.9943 for COD removal showed a satisfactory fit and consistency. The predictability of Multivariate Adaptive Regression Splines (MARS) method with R 2 = 0.95235 was significant compared to the Response Surface Methodology (RSM) with R 2 = 0.9599. The second-order kinetic equation performed better in terms of kinetic determination with k = 0.00009, E = 1.42776E+13, and R 2 = 0.9642 than the first-order model with k = 0.0159, E = 2.52237E+15, and R 2 = 0.9431.

The drilling and extraction operations aiming to maximize the production of oil may be counterbalanced by the huge production of contaminated water with pollutants, such as heavy metals and organic compounds. This review provides insight into the implementation of different technologies in the petroleum industry for treating PW generated from conventional oilfields in upstream and downstream processes. Scientific efforts in the future can concentrate on developing the most economical and environmentally compliant solutions for the management of untreated PW.
