“…Initial screening of commercially available hydrophobic membranes was carried out to identify those with high permeabilities suitable for this challenging application. The MD coefficients of the membranes evaluated in this study were significantly higher than those previously reported in the literature and the PTFE membranes used in this study exhibited substantially higher flux than that reported before for feed waters with a fairly high TDS content [34]. It was found that the properties of the membrane support layer (e.g., thickness and porosity) greatly influence the permeate flux and that highly porous support should be considered when selecting membranes for DCMD.…”

“…Several studies evaluated the use of MD to treat high salinity produced water from steam assisted gravity drainage process [31][32][33], oilfield produced water [34], coal seam gas produced water [35,36] and produced water generated from natural gas exploration [37]. The feed water used in these studies had total dissolved solids (TDS) ranging from 4000 to 70,000 mg/l and was concentrated up to 230,000 mg/l [37].…”

“…The feed water used in these studies had total dissolved solids (TDS) ranging from 4000 to 70,000 mg/l and was concentrated up to 230,000 mg/l [37]. Depending on the composition of feed water, the desired recovery factor and the heat source, the cost of produced water treatment using membrane distillation could range from 0.3 to 4.47 $/m 3 [31,34]. However, none of the studies with oil and gas produced waters included a comparison of different hydrophobic membranes or discussed the potential for membrane fouling by inorganic deposits that are likely to form at high water recoveries and after a prolonged period of operation.…”

A B S T R A C THydraulic fracturing used for natural gas extraction from unconventional onshore resources generates large quantities of produced water that needs to be managed efficiently and economically to ensure sustainable development of this industry. Membrane distillation can serve as a cost effective method to treat produced water due to its low energy requirements, especially if waste heat is utilized for its operation. This study evaluated the performance of commercially available hydrophobic microfiltration membranes in a direct contact membrane distillation system for treating very high salinity (i.e., up to 300,000 mg/L total dissolved solids) produced water. Polypropylene and polytetrafluoroethylene membranes yielded the highest permeate flux with membrane distillation coefficient of 5.6 l/m 2 /hr/kPa (LMH/kPa). All membranes showed excellent rejection of dissolved ions, including naturally occurring radioactive material (NORM), which is a significant environmental concern with this high salinity wastewater. Analysis of membranes after extended testing with actual produced waters revealed unevenly distributed inorganic deposits with significant iron content. A key finding of this study is that the iron oxide fouling layer had negligible effect on membrane performance over extended period of time despite its thickness of up to 12 µm. The results of this study highlight the potential for employing membrane distillation to treat high salinity wastewaters from unconventional gas extraction.

“…membrane based operations tested so far include microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO). Also, the coalition of membrane based procedures has been examined as an effective device to treat the produced water to meet the quality benchmarks of environmental standards [25].

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.

“…MD is an attractive option for treatment and reuse of impaired water sources because of its high rejection and high compatibility with renewable energy and low-grade waste heat sources [3]. MD provides nearly 100% rejection of non-volatile feed solutes [4][5][6][7][8] and it has been investigated for application to a variety of feed water sources including seawater [6,[9][10][11], brackish water [12], produced water [13][14][15], and various wastewater streams [16][17][18][19]. The benefits of MD make it an ideal candidate for water separation applications where renewable energy or lowgrade waste-heat sources are available.…”
