Abstract Membrane distillation is an emerging membrane technology, commonly used for desalination. The development of high performing and cheap membranes is one of the concerns for increasing the industrial applicability of the technology. In this paper, an economically interesting alternative has been found through the deposition of an atmospheric plasma coating on an inexpensive commercial hydrophilic membrane with a microporous structure. This coating enables obtaining the required hydrophobicity in order to retain the feed solution and preventing wetting of the membrane. The effect of the plasma discharge time on the membrane properties and membrane distillation performance was investigated. It was found that by using atmospheric plasma technology, very thin hydrophobic layers of a few μm can be obtained on top of a hydrophilic membrane structure. The thin hydrophobic layer obtained using this technology reduces the mass transport resistance, which results in very high fluxes at seawater salinity. This flux is equal to the flux of more expensive and supported thin PTFE membranes.

用于膜蒸馏的大气等离子涂层
摘要 膜蒸馏是一种新兴的膜技术,常用于海水淡化。高性能和廉价膜的开发是提高该技术工业适用性的关注点之一。在本文中,通过在具有微孔结构的廉价商业亲水膜上沉积大气等离子体涂层,发现了一种经济上有趣的替代方案。该涂层能够获得所需的疏水性,以保留进料溶液并防止膜润湿。研究了等离子体放电时间对膜性能和膜蒸馏性能的影响。人们发现,通过使用大气等离子体技术,可以在亲水膜结构的顶部获得几微米的非常薄的疏水层。使用该技术获得的薄疏水层降低了传质阻力,从而在海水盐度下产生非常高的通量。该通量等于更昂贵且有支撑的薄 PTFE 膜的通量。
