Special Issue Information

Dear Colleagues,

Membrane separation technology has been widely used for many applications, such as water treatment, seawater desalination, food processing, energy and resource production and separation and purification of pharmaceuticals, chemicals gases, CO2 capture, and so on. Membrane technologies offer intrinsic advantages such as a small footprint, easy operation, and high removal rates for many contaminants and pollutants. Membrane systems also represent a smart, flexible solution to develop sustainable remediation pathways with a limited environmental impact. However, the industrial applications of membrane technologies are still limited because of their low selectivity, poor stability, and fouling of membrane materials. Researchers from a different background (chemistry, physics, material science, and engineering) are working together to improve the performance of membrane processes.

This Special Issue on “State-of-the-Art Membrane Science and Technology in Australasia” aims to provide a comprehensive overview of membrane science in the Australasia region and will include both original research articles and reviews covering novel approaches in the field. Topics include but are not limited to the following:

  • Removal of chemicals of emerging contaminants;
  • Resource recovery from wastewater;
  • Membrane nanotechnology and polymer materials for energy and environmental applications;
  • Advanced membranes for gas separations, such as carbon dioxide capture, hydrogen upgrate, and nature gas perification, etc.;
  • Stimuli-responsive membranes for catalysis, energy recovery and biomedical applications.

Besides, the researches about biological membranes are also welcome.

The scope of this Special Issue includes that the main part of the study must be in Australia/New Zealand or by Australasian researchers. We expect that this Special Issue will provide some insights into future directions of membrane technologies from Australia/New Zealand and provide the remaining world with a bright image of what is carried out in the field in our country.

A three-dimensional model for the simulation of concentration polarisation in a full-scale spiral wound reverse osmosis (RO) membrane element was developed. The model considered the coupled effect of complex spacer geometry, pressure drop and membrane filtration. The simulated results showed that, at a salt concentration of 10,000 mg/L and feed pressure of 10.91 bar, permeate flux decreased from 27.6 L/(m2 h) (LMH) at the module inlet to 24.1 LMH at the module outlet as a result of salt accumulation in the absence of a feed spacer. In contrast, the presence of the spacer increased pressure loss along the membranes, and its presence created vortices and enhanced fluid velocity at the boundary layer and led to a minor decrease in flux to 26.5 LMH at the outlet. This paper underpins the importance of the feed spacer’s role in mitigating concentration polarisation in full-scale spiral wound modules. The model can be used by both the industry and by academia for improved understanding and accurate presentation of mass transfer phenomena of full-scale RO modules by different commercial manufacturers that cannot be achieved by experimental characterization of the mass transfer coefficient or by CFD modelling of simplified 2D flow channels.

The application of membrane technologies for wastewater treatment to recover water and nutrients from different types of wastewater can be an effective strategy to mitigate the water shortage and provide resource recovery for sustainable development of industrialisation and urbanisation. Forward osmosis (FO), driven by the osmotic pressure difference between solutions divided by a semi-permeable membrane, has been recognised as a potential energy-efficient filtration process with a low tendency for fouling and a strong ability to filtrate highly polluted wastewater. The application of FO for wastewater treatment has received significant attention in research and attracted technological effort in recent years. In this review, we review the state-of-the-art application of FO technology for sewage concentration and wastewater treatment both as an independent treatment process and in combination with other treatment processes. We also provide an outlook of the future prospects and recommendations for the improvement of membrane performance, fouling control and system optimisation from the perspectives of membrane materials, operating condition optimisation, draw solution selection, and multiple technologies combination.
