Membrane Life Cycle Management: An Exciting Opportunity for Advancing the Sustainability Features of Membrane Separations

Environmental Science & Technology, Год журнала: 2023, Номер 57(8), С. 3013 - 3020

Опубликована: Фев. 14, 2023

Membrane science and technology is growing rapidly worldwide continues to play an increasingly important role in diverse fields by offering high separation efficiency with low energy consumption. Membranes have also shown great promise for "green" separation. A majority of the investigations field are devoted membrane fabrication modification ultimate goals enhancing properties performance membranes. However, less attention has been paid life cycle management, particularly at end service. This becoming very important, especially taking into account trends toward sustainable development carbon neutrality. On contrary, this can be a opportunity considering large variety processes, terms size capacity plants operation. work aims highlight prominent aspects that govern management special assessment (LCA). While fabrication, application, recycling three key LCA, we focus here on (module) elucidating relevant aspects, potential criteria, strategies effectively contribute achievement green sustainability goals.

Over the last few decades, developing ultra-permeable nanofiltration (UPNF) membranes has been a focus research area to support NF-based water treatment. Nevertheless, there have ongoing debates and doubts on need for UPNF membranes. In this work, we share our perspectives why are desired We analyze specific energy consumption (SEC) of NF processes under various application scenarios, which reveals potential reducing SEC by 1/3 2/3 depending prevailing transmembrane osmotic pressure difference. Furthermore, could potentially enable new process opportunities. Vacuum-driven submerged NF-modules be retrofitted existing water/wastewater treatment plants, offering lower cost compared conventional systems. Their use in membrane bioreactors (NF-MBR) can recycle wastewater into high-quality permeate water, enables energy-efficient reuse single step. The ability retaining soluble organics may further extend NF-MBR anaerobic dilute municipal wastewater. Critical analysis development huge rooms attain improved selectivity antifouling performance. Our perspective paper offers important insights future technology, lead paradigm shift burgeoning field.
