“…For that reason, the oil droplets and fatty acids tend to adsorb on the membrane surface, and severely fouled the membrane. Similar findings were reported in previous studies [33,36]. On the other hand, both of the membrane materials and the droplets possess similar charges in basic feed solution, which enhances the repulsive force between the surface and the solutes.…”

“…It is clearly observed that the contact-angle values dropped at low pH and significantly rise at high pH for both TG and TG−FA mixtures, suggested that the wetting properties influenced by the changes in pH. It is reported in the literature that the zeta potential of the oil droplets was always negative [33]. Therefore, this might exert the strong interaction between the membrane surface and the solutes in acid solution, and enhance the wetting process.…”

“…Al-Jeshi et al [42] has conducted an experiment to test the ability of RO membranes to treat water containing up to 50% (by volume) of oil and to evaluate the effect of oil contamination on membrane performance whereby it is found that the RO membrane employed can only treat wastewater with up to 50% oil contamination. Besides having questionable ability in separation of oil in water emulsion, the high-pressure pump supplies the pressure needed to push water through the membrane, even as the membrane rejects the passage of salt through it which makes the process make use of more energy compared to other separation methods.…”

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.

“…Diversas técnicas de tratamento têm sido utilizadas para a redução de TOG da água como, por exemplo, extração por solvente [6] e separação por membrana [7][8][9] . No entanto, a possibilidade de emprego de resinas poliméricas porosas no tratamento da água produzida vem se intensificando em virtude de suas vantagens, como baixo custo, possibilidade de regeneração e reutilização, elevada seletividade e possibilidade de realização de modificações químicas por meio de reações tais como as realizadas para moléculas de baixa massa molar [10][11][12][13].…”

Resumo:Resinas poliméricas porosas têm sido amplamente empregadas nos processos de tratamento de água devido a vantagens como elevada seletividade e possibilidade de regeneração e modificação química, permitindo a obtenção de um material com maior seletividade/especificidade. No presente estudo, resinas poliméricas porosas de metacrilato de metila-divinilbenzeno (MMA-DVB), estireno-divinilbenzeno (Sty-DVB) e estireno-divinilbenzeno sulfonada (S-Sty-DVB) foram sintetizadas, caracterizadas e avaliadas quanto à eficiência de remoção de petróleo e de anilina contidos na água. Nos testes empregando-se água oleosa, foram avaliadas colunas contendo somente um tipo de resina (Sty-DVB e S-Sty-DVB) e colunas contendo recheios mistos (MMA-DVB/S-Sty-DVB e Sty-DVB/S-Sty-DVB), frente à remoção de óleo e dos cátions sódio e cálcio presentes na água oleosa. As colunas com recheio misto apresentaram melhor desempenho, devido à diversidade de hidrofilicidade do sistema adsorvente, tendo sido possível remover uma gama mais extensa de contaminantes. A remoção de anilina presente na água foi possível com o uso da resina de estireno-divinilbenzeno sulfonada, em razão da reação ácido-base entre a anilina e os sítios ácidos da resina. Uma redução gradual, e não abrupta, da eficiência desta resina na remoção de anilina deve-se à interação de moléculas de anilina com o sal de anilínio formado após a saturação dos sitos ácidos da resina.

Synthesis and Sulfonation of Macroporous Polymeric Resins and their Assessment for Removal of Oil and Aniline from WaterAbstract: Polymeric resins have been widely used in water treatment processes due to their advantages, such as high selectivity and possibility of regeneration and chemical modification, allowing obtaining a material with greater selectivity/specificity. In the present study, porous polymeric resins of methyl methacrylate-divinylbenzene (MMA-DVB), styrene-divinylbenzene (Sty-DVB) and sulfonated styrene-divinylbenzene (S-Sty-DVB) were synthesized, characterized and evaluated for their efficiency in removing oil and aniline contained in water. In the tests with oily water, the efficiency in removing oil and cations of sodium and calcium was assessed with columns containing only one type of resin (Sty-DVB or S-Sty-DVB) and columns containing blended filling (MMA-DVB/S-Sty-DVB and Sty-DVB/S-Sty-DVB). The columns containing the mixture performed better, due to the diverse hydrophilicity of the adsorbent system, allowing removal of a wider range of contaminants. The removal of aniline from the water was possible with the use of the sulfonated styrene-divinylbenzene because of the reaction between the aniline and acidic sites of the resin. The efficiency of this resin in removing aniline declined gradually rather than abruptly, due to the interaction of the aniline molecules with the aniline salt formed after saturation of the resin's acidic sites.
