“…Effluent from flotation systems and can achieve below 10 mg L À1 OIW through multiple stages need to be further treated in the presence of dissolved oil/hydrocarbons. Several post treatment techniques such as advance oxidation (Afzal et al, 2015), solvent sublation (Bayati et al, 2012), photo-fenton (da Silva et al, 2015) and membrane filtration (Alzahrani and Mohammad, 2014;Muraleedaaran et al, 2009) are used to remove toxic dissolved hydrocarbon substances from water (e.g. Gas field produced water).…”

“…United States Environmental Protection Agency (USEPA) approved the use of activated carbon in adsorption applications as one of the best available technologies for the removal of organic compounds from air and water treatment processes. Since oil is mainly composed of organic compounds, activated carbon materials could be considered a suitable adsorbent for its removal [7,8]. Okiel et al [11] conducted a study to remove emulsified oil from produced water using three different adsorbents, powdered activated carbon, deposited carbon, and bentonite.…”

Graphene and its magnetite derivative were used as adsorbents for removal of emulsified oil from produced water. The experimental parameters for maximum emulsified oil removal efficiency and effective regeneration of these adsorbents were determined. The best parameters in terms of dosage, contact time, pH, salinity and temperature were 3.00 g/L, 60.0 minutes, 10.0, 1500 ppm and 25.0 o C for graphene nanoplatelets, and 4.00 g/L, 30.0 minutes, 3.5, 1000 ppm and 25.0 o C, for graphene magnetite, respectively. Packed column studies were carried out utilizing graphene magnetite as adsorbent for the removal of oil from produced water. The packed column operation was assessed using Thomas, Yan et al., Clark, Bohart and Adams and Yoon and Nelson models. Thomas model was found to best describe the column experimental data. The column was regenerated using n-Hexane and reused several times for produced water treatment with negligible decrease in its initial capacity.

“…Water and oil are two of the major resource issues facing the world. After many oilfields were brought into the mid to late petroleum exploitation period [1][2][3], oily wastewater has become one key issue for the production process of the oilfield industry and environment protection [4][5][6]. In order to handle the oily wastewater issue, a cyclonic-static microbubble flotation column with a unique structure characterizing frother consumption has been introduced to the oil-water separation field [7][8][9].…”

A cyclonic-static microbubble flotation column of a novel construction was used in oil-water separation fields and has high efficiency for oil-water separation. The gas holdup is a key parameter for the evaluation of the performance of a flotation column. The gas holdup, closely related to the bubble size, bubble velocity and superficial gas velocity, is one of the most important parameters characterizing the hydrodynamics of a bubble column. The effect of gas holdup in a cyclonic-static microbubble flotation column was investigated. In addition, several operating parameters such as the circulating pressure, superficial gas velocity, and frother consumption were also investigated. The gas holdup was positively correlated to the superficial gas velocity. The gas holdup of clean water and oil wastewater increased along with the increase of the frother consumption. The separation mechanism of cyclonic-static microbubble flotation column was analyzed.
