“…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

“…These patterns of TPH degradation were reported by Zucchi et al 2003 andVinas et al 2005 . And similar studies carried out by Cerqueira et al 2011 , demonstrated the degradation of oil sludge by five pure culture isolates viz., Stenotrophomonas acidaminiphila, B. megaterium, B. cereus, B. cibi and Ps. aeruginosa.…”

A study on bioremediation of soil contaminated with petroleum sludge was performed using Bacillus pumilus/MVSV3 Accession number JN089707 . In this study, 5 kg of agricultural soil was mixed well with 5% oil sludge and fertilizers containing nitrogen, phosphorus and potassium-N:P:K . The treatment resulted in 97% removal of total petroleum hydrocarbon TPH in 122 d in bacteria mixed contaminated soil when compared to 12% removal of TPH in uninoculated contaminated soil. The population of the microorganism remained stable after introduced into the oil environment. The physical and chemical parameters of the soil mixed with sludge showed variation indicating improvement and the pH level decreased during the experiment period. Elemental analysis and Gas Chromatography-Mass Spectroscopy GC-MS analysis revealed the bacterial ability to degrade oil sludge components. Growth experiments with Trigonellafoenumgraecum Fenugreek showed the applicability of bioremediated soil for the production.

“…Specifically, in the PFR systems, the families Comamonadaceae and Xanthomonadaceae comprised more than 50% of the population, fol- lowed by the Burkholderiaceae family. Members of the Xanthomonadaceae family are obligate aerobes, and some of them have been directly or indirectly related to petroleum hydrocarbon degradation (45,46). The family Comamonadaceae belonging to the order Burkholderiales harbor a remarkable phenotypic diversity, while members of the Burkholderiaceae family from the same order have been found in diverse ecological niches.…”

In the present study, microbial toluene degradation in controlled constructed wetland model systems, planted fixed-bed reactors (PFRs), was queried with DNA-based methods in combination with stable isotope fractionation analysis and characterization of toluene-degrading microbial isolates. Two PFR replicates were operated with toluene as the sole external carbon and electron source for 2 years. The bulk redox conditions in these systems were hypoxic to anoxic. The autochthonous bacterial communities, as analyzed by Illumina sequencing of 16S rRNA gene amplicons, were mainly comprised of the families Xanthomonadaceae, Comamonadaceae, and Burkholderiaceae, plus Rhodospirillaceae in one of the PFR replicates. DNA microarray analyses of the catabolic potentials for aromatic compound degradation suggested the presence of the ring monooxygenation pathway in both systems, as well as the anaerobic toluene pathway in the PFR replicate with a high abundance of Rhodospirillaceae. The presence of catabolic genes encoding the ring monooxygenation pathway was verified by quantitative PCR analysis, utilizing the obtained toluene-degrading isolates as references. Stable isotope fractionation analysis showed low-level of carbon fractionation and only minimal hydrogen fractionation in both PFRs, which matches the fractionation signatures of monooxygenation and dioxygenation. In combination with the results of the DNA-based analyses, this suggests that toluene degradation occurs predominantly via ring monooxygenation in the PFRs. Biology-based remediation technologies (bioremediation) for the treatment of groundwater and soils polluted with organic compounds have been receiving high interest due to their low cost, high efficiency, and relative operational simplicity (1). Rhizoremediation is one such effective bioremediation approach, where the transformation of contaminants to innocuous products may be enhanced by plant-microbe interactions occurring in the rhizosphere (2-4). The plants provide the rhizospheric microbial community with root exudates such as carbohydrates, amino acids/amines, and organic acids (5) and thus promote the microbes' establishment and proliferation. Rhizoremediation is particularly effective in constructed wetlands. These treatment systems have been applied for the removal of even high loads of contaminants present in inflow waters (6-8). In addition to the input of labile organic carbon, the helophytes used in these systems have the capacity of channeling significant amounts of oxygen from the atmosphere through a specific tissues, the aerenchyma, into their roots, and thereby foster aerobic microbial activities in the rhizosphere (9).In order to enhance the performance of constructed wetlands through engineering optimizations of the systems, it is deemed necessary to understand the functionality of the relevant microbial community present in the rhizosphere, and some efforts have been pursued in this direction (7, 10). However, due to the presence of steep chemical gradients and variable environmental ...
