“…The authors reported that the feed flow rate has a high impact on trans-membrane pressure; however, the increase in the ceramic membrane's porosity did not significantly influence the system's performance. Tong et al [12] used CFD modeling of a 19-core ceramic membrane to investigate the flow rate's effect on the membrane module's resistance. The authors reported that with an increase in the flow rate from 26 to 89 m 3 /h, the resistance of the membrane system grows continuously.…”

Multi-channel microfiltration (MF) membranes are considered as one of the most efficient separation methods for wastewater treatment, mainly due to their relatively high thermal and chemical resistance. Among various types of MF membranes, Ceramic Membranes attract great attention because of their high active area and superb mechanical strength, making them an industrially applicable pretreatment process for Reverse Osmosis (RO) unit operation. Here, a thorough 3-dimensional modeling of a 19-channel Ceramic Membrane was employed in order to gain insight into pressure drop, velocity distribution, and concentration profile in each channel. Experimental data from a lab-scale multi-channel Ceramic Membrane fed with oily wastewater was used to validate the model. The permeate flux was predicted as 200 to 250 L/m2.hr based on the porous media transmission pressure in such configurations. Further, permeate mass flux was also calculated based on the inlet flow velocities ranging from 0.75 to 2.25 m/s.

“…Some new multi-channel membrane structures with more osmotic channels are proposed and evaluated. Yujia Tong et al [21] established CFD simulation of the permeation process of a 19-core series ceramic membrane module, and studied the flow field and resistance as well as their changes on the position of the membrane element and the permeation flux of each membrane element channel. Through the simulation, the flow mechanism in the module can be elucidated, which provides a reliable basis for optimizing the equipment structure and improving the industrial ceramic membrane module.…”

Inorganic ceramic membrane has been widely used in the field of fluid filtration, purification and separation. The flow characteristics of fluid passing through ceramic membrane are very important for its filtration and purification efficiency. Computational fluid dynamics (CFD) technology can simulate the fluid field rules and predict its application effect, so as to optimize the membrane structure and performance. This paper reviews the application of inorganic ceramic membrane and the application of CFD technology in the optimization of the structure of the inorganic ceramic membrane module and filtration purification separation, and makes a prospect for its future development.

“…In this very interesting paper, the authors have concluded that the permeate efficiency of the inner channels is smaller than that of the outer channels and that the difference in permeate flux of a channel in different radial rings diminishes gradually as the resistance of the skin layer increases. Tong et al [ 54 ] reported a similar CFD study using a 19-core tandem ceramic membrane module. The authors concluded that when the volume flow rate changes from 26 to 89 m 3 /h, the resistance of each part of the membrane module system increases gradually.…”

“…In this context, the CFD (Computational Fluid Dynamics) technique provides information and new models for the application of membranes and contributes to the understanding of the filtration mechanisms [ 43 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 ]. The computational fluid dynamics enables the understanding and development of new membrane separation processes, allowing researchers to study, in detail, phenomena such as fouling, concentration polarization, and pore-clogging, responsible for reducing the filtration rate and favoring contamination of the permeate.…”

Wastewater from the oil industry can be considered a dangerous contaminant for the environment and needs to be treated before disposal or re-use. Currently, membrane separation is one of the most used technologies for the treatment of produced water. Therefore, the present work aims to study the process of separating oily water in a module equipped with a ceramic membrane, based on the Eulerian–Eulerian approach and the Shear-Stress Transport (SST k-ω) turbulence model, using the Ansys Fluent® 15.0. The hydrodynamic behavior of the water/oil mixture in the filtration module was evaluated under different conditions of the mass flow rate of the fluid mixture and oil concentration at the entrance, the diameter of the oil particles, and membrane permeability and porosity. It was found that an increase in the feed mass flow rate from 0.5 to 1.5 kg/s significantly influenced transmembrane pressure, that varied from 33.00 to 221.32 kPa. Besides, it was observed that the particle diameter and porosity of the membranes did not influence the performance of the filtration module; it was also verified that increasing the permeability of the membranes, from 3 × 10−15 to 3 × 10−13 m2, caused transmembrane pressure reduction of 22.77%. The greater the average oil concentration at the permeate (from 0.021 to 0.037 kg/m3) and concentrate (from 1.00 to 1.154 kg/m3) outlets, the higher the average flow rate of oil at the permeate outlets. These results showed that the filter separator has good potential for water/oil separation.
