“…Recently Abdullah et al [40] has successfully synthesized a new type of adsorptive microporous UF membranes that were composed of an organic polysulfone (PSf) and inorganic HFO nanomaterial and has helped in removal of lead in the wastewater. Meanwhile Luo et al [41] has employed ultrafiltration of oil-water separation using triangleshape tri-bore hollow fibre membrane from sulfonated PSf and the result has shown that the water permeates after filtration are very clear with low turbidity.…”

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

Effects of manganese(VI) oxide on polyacrylonitrile-based activated carbon nanofibers (ACNFs) and its preliminary study for adsorption of lead(II) ions

In this work, the effect of adding manganese oxide towards polyacrylonitrile-based activated carbon nanofibers (ACNFs) was evaluated. The properties of PAN-based ACNFs/MnO 2 were analyzed by using scanning electron microscopy (SEM), BrunauerEmmett-Teller (BET), and Fourier transform infrared (FTIR). The sorption study of the electrospun ACNFs/MnO 2 in comparison to neat ACNFs and commercial granular AC towards lead (Pb) was also conducted. SEM micrograph analysis displays more compact nanofibers with dispersion of beads that were observed in the ACNF/MnO 2 with the diameter of 437.2 nm while aligned nanofibers with the diameter of 575.5 nm were observed in the neat ACNFs. The FTIR analysis showed the peak of Mn-O, which indicates the presence of MnO 2 in the ACNFs/MnO 2. In comparison to the neat ACNFs, surface area of the prepared ACNFs/MnO 2 is lower. It was found out that the removal of Pb(II) using ACNFs and ACNFs/MnO 2 is higher than commercial granular activated carbon with a removal rate of 100% at initial concentration of 3.5 ppm. The promising results of ACNFs/MnO 2 contributed by their satisfactory specific surface area and vast presence of surface functional groups.

“…In order to have pollution-free environment, the heavy metals should be removed from the waste water before its disposal. Various methods have been developed to eliminate Pb 2+ and Zn 2+ content in water, including ion exchange [3], reverse osmosis [4] and adsorption [5,6,7,8]. Among of these, adsorption process is one of the effective techniques that has been successfully employed for heavy metals removal from wastewater due to its simplicity of design, easy to operate and can work at low concentrations.…”

Abstract. Coal fly ash (CFA), which is a solid waste generated in large amounts worldwide, is mainly composed of some oxides having high crystallinity, including quartz (SiO2) and mullite (3Al2O3 2SiO2), and unburned carbon as a mesopore material that enables it to act as a dual site adsorbent. To decrease the crystallinity, CFA was modified by sodium hydroxide treatment. The modified fly ash (MFA) contains lower amount of Si and Al and has a higher specific surface area than the untreated fly ash (CFA).
