Special Issue Information

Dear Colleagues,

We are delighted to invite you to submit your original research work to the upcoming Special Issue of Membranes on Membrane Distillation. Membrane distillation is a rapidly growing technology with great potential in various fields including desalination, wastewater treatment, food industry, and pharmaceutical production. Membrane distillation has distinct advantages over traditional separation techniques such as low fouling tendency, high separation efficiency, and the ability to operate at low temperatures and pressures.

This Special Issue aims to compile recent advances in membrane distillation technology and its applications, presenting them alongside emerging challenges and potential solutions. We welcome original research articles, reviews, and perspectives on various aspects of membrane distillation. Potential topics include, but are not limited to:

  • Novel membrane materials and structures;
  • Advanced membrane distillation configurations and systems;
  • Fouling and scaling phenomena and mitigation strategies;
  • Modeling and simulation of membrane distillation processes;
  • Applications of membrane distillation in desalination, wastewater treatment, and other areas.

The purpose of this Special Issue is to provide a comprehensive platform to enable researchers, engineers, and scientists to share their knowledge and experiences in the field of membrane distillation. We hope that this collection of articles will serve as a valuable reference for the scientific community and provide insights for future research and development.

We look forward to your contributions to this Special Issue, and we hope that you find this topic both interesting and relevant to your research.

Abstract
In order to enhance the separation performance and reduce the heat loss of transmembrane for membrane distillation, the thermal efficiency and hydrophobicity of the membrane distillation need to be simultaneously enhanced.

In order to enhance the separation performance and reduce the heat loss of transmembrane for membrane distillation, the thermal efficiency and hydrophobicity of the membrane distillation need to be simultaneously enhanced. In this work, a polyvinylidene difluoride/polyethylene glycol terephthalate (PVDF/PET) hydrophobic/hydrophilic membrane has been prepared by non-solvent phase induction method. Nanosized silica aerogel (SiAG) with high porosity has been added to the composite membranes. The modifying effects and operating conditions on permeate flux and thermal efficiency in direct contact membrane distillation (DCMD) are investigated. Furthermore, the latent heat of vaporization and the heat transfer across the membranes have been compared for SiAG addition, which indicates that the composite PVDF@SiAG/PET membranes demonstrate a great potential for distillation-separation application due to their high heat efficiency.

Finned tubular air gap membrane distillation is a new membrane distillation method, and its functional performance, characterization parameters, finned tube structures, and other studies have clear academic and practical application value. Therefore, the tubular air gap membrane distillation experiment modules composed of PTFE membrane and finned tubes were constructed in this work, and three representative air gap structures, including tapered finned tube, flat finned tube, and expanded finned tube, were designed. Membrane distillation experiments were carried out in the form of water cooling and air cooling, and the influences of air gap structures, temperature, concentration, and flow rate on the transmembrane flux were analyzed. The good water-treatment ability of the finned tubular air gap membrane distillation model and the applicability of air cooling for the finned tubular air gap membrane distillation structure were verified. The membrane distillation test results show that with the tapered finned tubular air gap structure, the finned tubular air gap membrane distillation has the best performance. The maximum transmembrane flux of the finned tubular air gap membrane distillation could reach 16.3 kg/m2/h. Strengthening the convection heat transfer between air and fin tube could increase the transmembrane flux and improve the efficiency coefficient. The efficiency coefficient (σ) could reach 0.19 under the condition of air cooling. Compared with the conventional air gap membrane distillation configuration, air cooling configuration for air gap membrane distillation is an effective way to simplify the system design and offers a potential way for the practical applications of membrane distillation on an industrial scale.
