This paper investigates the adsorption of oil, chemical oxygen demand (COD) and turbidity of the produced water (PW) which accompanies the oil exploration and production after treatment by using powdered activated carbon (PAC), clinoptilolite natural zeolite (CNZ) and synthetic zeolite type X (XSZ). Moreover, the paper deals with the comparison of pollutant removal over different adsorbents. Sorption was carried out in batch sorption system. The operating factors including adsorbent dosage, time, pH, oil concentration and temperature were investigated to determine the optimum operational conditions. Three adsorption isotherm models (Langmuir, Freundlich and Temkin models) were applied. The kinetics of the oil sorption and the change in COD content over on PAC and CNZ were studied by using pseudo-first order and pseudo-second order kinetics models. Maximum oil removal efficiencies (99.57, 95.87 and 99.84%), COD and total petroleum hydrocarbon (TPH), respectively were found at PAC adsorbent dose of 0.25 g/100 mL. However, maximum turbidity removal efficiency (99.97%) was obtained when zeolite X was used at 0.25g/100 mL concentration. It is not very different from that obtained over PAC (99.65%). The results proved that adsorption over PAC is most effective compared to zeolites in the removal of organic pollutants from PW. Also, regeneration of the consumed adsorbents was carried out in this work to find out the possibility of reusing the adsorbents. The consumed powdered activated carbon and zeolites can be effectively regenerated and reused by chemical treatment and thermal treatment respectively.

This paper studied the adsorption of chemical oxygen demand (COD), oil and turbidity of the produced water (PW) which accompanies the production and reconnaissance of oil after treating utilizing powdered activated carbon (PAC), clinoptilolite natural zeolite (CNZ) and synthetic zeolite type X (XSZ). Moreover, the paper deals with the comparison of pollutant removal over different adsorbents. Adsorption was executed in a batch adsorption system. The effects of adsorbent dosage, time, pH, oil concentration and temperature were studied in order to find the best operating conditions. The adsorption isotherm models of Langmuir, Freundlich and Temkin were investigated. Using pseudo-first-order and pseudo-second-order kinetic models, the kinetics of oil sorption and the shift in COD content on PAC and CNZ were investigated. At a PAC adsorbent dose of 0.25 g/100 mL, maximum oil removal efficiencies (99.57, 95.87 and 99.84 percent), COD and total petroleum hydrocarbon (TPH) were identified. Moreover, when zeolite X was used at a concentration of 0.25 g/100 mL, the highest turbidity removal efficiency (99.97%) was achieved. It is not dissimilar to what you would get with PAC (99.65 percent). In comparison with zeolites, the findings showed that adsorption over PAC is the most powerful method for removing organic contaminants from PW. In addition, recycling of the consumed adsorbents was carried out in this study to see whether the adsorbents could be reused. Chemical and thermal treatment will effectively regenerate and reuse powdered activated carbon and zeolites that have been eaten. Graphic abstract

“…This behavior is attributed probably to the active surface area which was negatively affected by the presence of the repulsive force between the oil adsorbed on the surface of WWP or the aggregation formed by the adhesion of the adsorbents to each other. [ 31 ]…”

Waste motor oil (WMO), which has no stable form or structure, causes major environmental problems and damage to the ecosystem once it is disposed to the environment. Because of the high toxicity of contents in such effluent, it must be treated before being discharged into the receiving environment. In recent years, the valorization and the use of waste materials to remove toxic pollutants is of great importance to researchers and diverse industries. In this study, the usability of waste welding powder (WWP) as an adsorbent for waste oil removal was investigated. For this purpose, investigating the usability of material, which is generated as industrial waste, in wastewater treatment will lead to the evaluation of waste. The effects of temperature, pH, WWP amount, and initial WMO amount were investigated. According to the adsorption studies, 1 g WWP/L of the processed adsorbent was able to effectively remove 95.05% of WMO (100 mg) at a pH of 2 at 30°C. Stereo microscopy images showed a large amount of oil adsorbed on the WWP surface. The different WWP properties were determined by adsorption isotherm (Harkins–Jura), kinetic (pseudo‐second order), and thermodynamic (ΔG: −5.1 kJ mol–1) experiments. It is thought that WWP, which is a low‐cost and waste material, can be used as a promising adsorbent in WMO removal.
