“…The employment of mixed bacterial culture has demonstrated to be more advantageous in comparison with pure culture due to synergistic interactions among members of the associations [19]. Due to characteristics of poor nutrients of nitrogen and phosphorus, low BOD/COD ratio, high toxicity, oilfield produced water is difficult to be treated by a simple biological treatment [20].…”

The oil and gas industry has been a constant developing industry as it is of importance to the maintenance of industrial civilization in its current configuration and play vital roles in many other industries. Some oil and gas industry operations have been accountable of water contamination through by-results of refining and oil slicks. One of the biggest by-products that have raised a critical environment concern is oilfield produced water. Oilfield produced water (OPW) is coproduced aqua liquid phase which originate from well alongside oil phases in normal production process. The content of OPW consists of different type of organic and inorganic mix. Discarding this kind of wastewater can lead to surface pollution especially on water sources as well as soil. Hence, to meet environmental regulations as well as reuse and recycling of produced water, many researchers have focused on treating oily saline produced water. Conventional technologies used to treat produced water consist of clarifiers, dissolved air flotation, hydro cyclones, and disposable filters/absorbers. Typically, additional chemicals for coagulation or settling are needed which are expensive and are incapable of achieving recently required standards of cleanliness. Therefore, researchers have swung to membrane filtration plans because of their capability to minimize extra expenses and surpass issues connected with current advances. Thus, the purpose of this review is to highlight the current and developed membrane technology used in treating the oilfield produced wastewater and its current progress.Keywords: oilfield produced water, membrane filtration, mixed matrix membrane, oily wastewater Abstrak Industri minyak dan gas telah menjadi industri membangun berterusan kerana ia adalah penting untuk mengekalkan tamadun perindustrian dalam konfigurasi semasa dan memainkan peranan penting dalam banyak industri lain. Sesetengah operasi industri minyak dan gas telah dipertanggungjawabkan ke atas pencemaran air melalui tindakan penapisan dan minyak tumpahan. Salah satu yang produk sampingan yang terbesar yang telah menimbulkan kebimbangan persekitaran kritikal adalah air yang dihasilkan medan minyak. Air yang dihasilkan dari medan minyak (OPW) adalah dihasilkan bersama fasa cecair dan fasa minyak yang berasal dari telaga minyak dalam proses pengeluaran normal. Kandungan OPW terdiri daripada pelbagai jenis campuran organik dan bukan organik. Pembuangan jenis air sisa ini boleh membawa kepada pencemaran permukaan terutamanya kepada sumber air dan tanah. Oleh itu, untuk memenuhi peraturan-peraturan alam sekitar serta penggunaan semula dan kitar semula air yang dihasilkan, ramai penyelidik telah memberi tumpuan kepada merawat air masin yang dihasilkan dari medan minyak ini. Teknologi konvensional yang digunakan untuk merawat air yang dihasilkan terdiri daripada clarifiers, pengapungan udara terlarut, siklon hidro dan penapis boleh guna/penyerap. Biasanya, bahan kimia tambahan untuk pembekuan

“…An MBBR treating oilfield-produced water attained a COD removal level of 74% at a TPH loading rate of 2.6 g/m 3 h [2]. The treatment of heavy oil wastewater in an upflow anaerobic sludge blanket combined with a biological aerated filter was investigated by Liu et al [5]. They observed an average COD removal of 74% for oil loading rates between 2.1 and 26.3 g/m 3 h. TPH-laden wastewater was treated in an upflow anoxic fixed-bed reactor (UAnFB) and in a sequencing anoxic batch reactor (SAnBR); TPH removal levels of 93.6-99.6% for the UAnFB and 87.7-98.7% for the SAnBR were attained at similar TPH loading rates of 39.6-104.2 g/m 3 h [8].…”

“…Compared with physicochemical processes, biological treatments are the most accepted technology for controlling waste streams containing organic contaminants, because they are environmentally benign, reliable, and feasible, have the ability to achieve high removal efficiency, and are highly compatible with existing facilities. Further reasons include their simplicity of design, construction and operation, relatively low energy usage, and the biodegradation instead of accumulation of hydrocarbons in another phase or of degradation using chemical agents, and thus cost-effectiveness [2,[4][5][6][7]. In a biological process, microorganisms utilize hydrocarbons as their sole energy and carbon source and thus biodegrade them instead of accumulating them in another phase [7,8].…”

“…A combined sludge-blanket/fixed-film bioreactor has promising characteristics that allow the exploitation of the unique benefits of both processes in a single bioreactor. It has been reported that the combined anaerobic suspended growth and fixed-film bioreactors performed better than the single ones in removing TPH from waste streams [2,5,7,15,16]. However, information regarding the performance (removal efficiency and rate) of hydrocarbon biodegradation under anoxic conditions in combined bioreactors is not available.…”

“…Some of these technologies are based on separation process such as Flotation [3,4], membrane with different types and materials [5,6]. Other technologies are based on oil degradation either by biological process [7,8], or by chemical oxidation processes [9][10][11][12].…”

The lube oil wastewater is produced from Lube Oil Bending Facilities (LOBF) located in Egypt. Currently the lube oil wastewater is treated by oil separator followed by Dissolved Air Flotation (DAF) system. Unfortunately, DAFTreated Lube Oil Wastewater (DTLOWW) contains high concentration of the soluble COD.The first part of this work examined the treatability of DAF-Treated Lube Oil Wastewater (DTLOWW) using bench-scale Fenton process. Effects of H 2 O 2 , Fe 2+ doses at different reaction time and wastewater strength have been studied. Optimum H 2 O 2 dose was 0.8 g/l for normal DTLOWW strength (sCOD<2000 mg/l) and 1.2 g/l for high DTLOWW strength (sCOD>2000 mg/l). Optimum H 2 O 2 /FeSO 4 ratio of 3 was achieved for the normal and high strength DTLOWW at pH 3.5.The Second part of this work studied the performance of Pilot-scale Fenton process. Pilot scale Fenton reactor was installed in the field and conducted under the optimum H 2 O 2 /FeSO 4 ratio that achieved from the bench scale work. The reactor was operating in batch basis at 8 hour cycle period divided in six phases. The results showed that residual sCOD was 788 ± 56 mg/l with sCOD removal of 53.6% which amply met with the local discharge Standards for discharging the industrial wastewater to the municipal sewage network. The Fenton process could be used for treatment of the DTLOWW with daily chemicals cost of 1.25-1.50 $/m 3 .
