It describes zeolitic materials and methods of membrane fabrication, followed by a summary of applications for gas separation, pervaporation and separation of liquid mixtures. Special attention is called to polymer mixed matrix membranes (MMMs) and membranes based on metal organic frame works (MOFs). In this comprehensive survey, the following trends were observed during the past 5 – 10 years. New zeolitic materials and new synthesis methods, such as hydrothermal synthesis, seeding and microwave heating, have been continuously reported in the literature. Many efforts have been devoted to the synthesis of hybrid or mixed matrix membranes (MMMs) since MMMs clearly outperformed polymeric membranes. MOFs also showed improved performance in gas separation. Many attempts have been made to develop thin (1µm) supported zeolite layers on a variety of carriers such as capillaries, fibers, tubes, etc. The assembly of nanozeolite building blocks and nanosheets is the starting point for the synthesis of thin defect free zeolite membranes. The present review presents the recent progresses made in the field of zeolite/zeotype membranes. Different types of zeolite membranes, methods of preparation and application aspects especially for separation of gases have been focused on, including the individual zeolites which are in use or are to be used as inorganic fillers in mixed matrix membranes (MMMs). Despite the enormous efforts of researchers, the commercialization of zeolite membranes has been achieved only in a limited area. The future works necessary to change the current situation are hence suggested.}, keywords = {Inorganic membrane,Zeolite,Membrane preparation,Membrane application}, url = {https://www.msrjournal.com/article_13530.html}, eprint = {https://www.msrjournal.com/article_13530_f812999e94ccfd5db3fa97f78edf18b1.pdf} } @article { author = {Xu, Nong and Su Kim, Sung and Li, Anwu and Grace, John R. and Lim, C.

A novel complexing plating bath of Ru was developed. It is proven that Ru can be deposited directly on these substrates by the bath at a temperature of 328 K and strong alkaline environment. TGA, SEM, EDX and XRD confirmed the successful deposition of Ru. Relationships among plating rate, plating time, plating bath temperature and concentrations were also investigated. The Ru plating procedure was optimized. Based on the optimized procedure, a Ru layer was deposited by electroless plating of Ru onto the surface of pretreated aluminum-oxide modified PSS substrate. A 7.6 µm thick Pd-Ru membrane could be fabricated by electroless plating with a palladium (Pd) layer overlying the PSS substrate and a Ru layer overlying the Pd layer. Helium leakage and hydrogen permeation tests confirmed that the membrane was free of defects. Hydrogen diffusion through the Pd-Ru membrane was found to be the rate-controlling step in permeation. A new Pd-Ru composite membrane had the same features and permeation behavior as a previous one, indicating that electroless plating of both Ru and Pd is reliable and repeatable.}, keywords = {Ruthenium (Ru),Electroless plating,Palladium (Pd),Pd-Ru composite membrane,Hydrogen separation}, url = {https://www.msrjournal.com/article_13532.html}, eprint = {https://www.msrjournal.com/article_13532_0f1457fd762850932cb8d044b60d3571.pdf} } @article { author = {Subagjo, S. and Prasetya, N. and Wenten, I.G.}, title = {Hollow Fiber Membrane Bioreactor for COD Biodegradation of Tapioca Wastewater}, journal = {Journal of Membrane Science and Research}, volume = {1}, number = {2}, pages = {79-84}, year = {2015}, publisher = {FIMTEC & MPRL}, issn = {2476-5406}, eissn = {2476-5406}, doi = {10.22079/jmsr.2015.13533}, abstract = {The present work studied the application of membrane bioreactor (MBR) for tapioca wastewater processing that contained chemical oxygen demand (COD) ranging from 4000-9000 mg/L. A preliminary study was initially conducted in order to evaluate membrane performance with respect to its flux with MLSS concentration ranging from 4,500 to 10,500 mg/L. It was clear that fouling was observed during the initial period of study for the whole range of MLSS concentration resulting in drastic flux decline. Increasing trans-membrane suction pressure only yielded slight flux enhancement in 4,500 MLSS concentration. The contrast result was found for both 8,500 and 10,500 MLSS concentration. However, their flux performance could be increased by applying aeration to the system. In batch operation mode using tapioca wastewater, a slight decrease in COD removal was observed when lower hydraulic retention time (HRT) was applied. Lower HRT also suffered relatively sharper flux decline. However, COD removal was only slightly affected by HRT. In a continuous operation mode, it was observed that above 94% COD removal could be attained using HRT in about 24 hours. However, MBR suffered severe membrane fouling in the 4th day of operation resulting in a drastic flux drop below 1 lmh. The chemical cleaning mechanism employed in MBR was found to give the most prominent result since around 67% of flux recovery could be achieved.}, keywords = {Tapioca wastewater,Membrane bioreactor (MBR),COD removal,Wastewater treatment}, url = {https://www.msrjournal.com/article_13533.html}, eprint = {https://www.msrjournal.com/article_13533_8f9667bc62d7242fda0910d5784244fa.pdf} } @article { author = {Takht Ravanchi, Maryam and Kaghazchi, Tahereh and Kargari, Ali}, title = {Effect of Complexation Reaction Constant on the Separation of Propylene/Propane by Supported Liquid Membrane}, journal = {Journal of Membrane Science and Research}, volume = {1}, number = {2}, pages = {85-89}, year = {2015}, publisher = {FIMTEC & MPRL}, issn = {2476-5406}, eissn = {2476-5406}, doi = {10.22079/jmsr.2015.13536}, abstract = {Traditional systems for olefin/paraffin separation, like low-temperature distillation, are expensive and very energy consuming, and therefore, alternative separation methods are desired.

Due to the numerous advantages and wide applications of carbon membranes, their application for gas separation is of special importance. Because of the importance of carbon membranes and a large number of studies in the field of carbon membrane fabrication, in this study, mathematical modeling of the gas separation process in CMSMs has been investigated. Flat configuration is considered for the membrane, which has been applied for the separation process of CH4 and C2H6. The Runge-Kutta method has been applied in order to solve the model. In the mentioned model, the sorption-diffusion mechanism has been considered as a dominant one for gas separation with CMSM. By comparing theoretical results with experimental ones for binary diffusion, good agreement was obtained. Finally, the effect of some parameters such as effective area of the module, module temperature, total feed pressure and feed flow rate on the purity of components in the retentate and permeate stream and recovery of fast components in the permeate stream have been investigated. Results demonstrated that increasing the effective area, membrane temperature and total feed pressure increased the recovery of the fast component in the permeate side, while the feed flow rate had an adverse effect.}, keywords = {Carbon molecular sieve membrane,CMSM,Flat membrane,Gas separation,Modeling}, url = {https://www.msrjournal.com/article_13537.html}, eprint = {https://www.msrjournal.com/article_13537_cee0ff130f9f918a4ce6da9f3b96f048.pdf} } @article { author = {Belousov, V.V. and Fedorov, S.V. and Kul`bakin, I.V.}, title = {Hybrid Molten/Solid In2O3-Bi2O3 Oxygen Ion Transport Membranes}, journal = {Journal of Membrane Science and Research}, volume = {1}, number = {2}, pages = {96-99}, year = {2015}, publisher = {FIMTEC & MPRL}, issn = {2476-5406}, eissn = {2476-5406}, doi = {10.22079/jmsr.2015.13538}, abstract = {The hybrid molten/solid In2O3 - 30-48 wt.% Bi2O3 oxide materials were studied with respect to their transport properties.
