Advanced Application and Fouling Control in Hollow Fibre Direct Contact Membrane Distillation (HF-DCMD)

Evaluation of anti‐wetting nano‐fumed silica/PVDF hollow‐fiber membrane by central composite design optimization towards efficient desalination performance via membrane distillation

“…The key point is to enhance the desalination performance and increase the anti-wetting and fouling resistance by synthesizing an ideal membrane. 14,15 Earlier studies have verified that the anti-wettability of MD membranes is obtained by their surface characteristics and geometric assemblies. 16 On the other hand, the preferable type of choice by experts is using hollow-fiber (HF) membranes in MD applications because of their lower sensitivity to temperature polarization, self-supporting property flexibility and large surface area per unit volume.…”

Enhancing Hydrophobic/Hydrophilic Dual-Layer Membranes for Membrane Distillation: The Influence of Polytetrafluoroethylene (PTFE) Particle Size and Concentration

“…As MD technology continues to evolve, the optimization of membrane characteristics-such as those investigated in this study-becomes a crucial 2 of 31 factor in enhancing performance while minimizing resource utilization, thus contributing to the broader goals of water and energy sustainability [4]. MD has several key advantages, one of which is its ability to handle solutions and waters that have a high concentration of salt or other impurities; this particular feature makes MD very popular among seawater desalination or wastewater treatment techniques [5][6][7][8]. MD is also considered to be one of the more energy-efficient techniques among other desalination methods, as it is not reliant on high pressure in order to operate and produce high-quality water [9].…”

Potential effects of nano‐fumed silica particles (NFS)/PVDF mixed matrix hollow fiber membrane on the performance of direct contact membrane distillation

“…9,10 Hollow fiber (HF) membranes are the preferable choice by researchers compared with the flat sheet membranes in MD applications due to their less sensitivity to temperature polarization, flexibility, selfsupporting property, and large surface area per unit volume. [11][12][13] In the last decade, researchers have carried out different approaches such as blending, surface grafting, surface coating, and preparation of dual-layer composite membranes to enhance fabricating a hydrophobic PVDF membrane in terms of flux, retention rate, and stability in MD. 14 However, blending is the most frequently used technique among the other methods to optimize the membrane structure and build anti-wetting properties in MD.…”

“…The key factors that a membrane should have for an effective MD process are high hydrophobicity, high porosity, optimal thickness, good chemical resistance strength, acceptable mechanical strength, anti‐fouling characteristic, high liquid entry pressure (LEP w ), narrow pore size distribution, low vapor transport resistance, and reduced thermal conductivity 9,10 . Hollow fiber (HF) membranes are the preferable choice by researchers compared with the flat sheet membranes in MD applications due to their less sensitivity to temperature polarization, flexibility, self‐supporting property, and large surface area per unit volume 11–13 …”
