Abstract

Membrane distillation (MD) is a highly promising method for desalinating water with high salt content. However, a major challenge faced by this technology is its high energy consumption, which is caused by the need to heat up the saline feed solution. Hence, this study aimed to incorporate multi-walled carbon nanotubes (MWCNTs) into the polysulfone (PSF) matrix to fabricate composite photothermal MD membranes. These membranes have the capability to function independently without the need for an external energy source. Various quantities of MWCNTs ranging from 0.5 to 1.5% (by weight) were added to the PSF casting solution. This led to the creation of composite membranes with improved photothermal characteristics. The PSF and PSF/MWCNTs composite membranes were analyzed using scanning electron microscopy (SEM), FTIR spectroscopy, thermal gravimetric analysis, and contact angle measurements. The concentration of MWCNTs that yielded the highest photothermal efficiency was found to be 1% (by weight). The membranes were assessed using a photothermal membrane distillation (PMD) device, where the operational conditions and parameters were investigated. The presence of MWCNTs resulted in an increase in the surface temperature of the membrane to 67 °C when placed 10 cm away from a 200 W light source. In addition, the inclusion of MWCNTs led to a rise in the contact angle measurement from 80° to 112°, as well as an improvement in the liquid entry pressure (LEP) from 25.5 to 52 psi. Moreover, it significantly impacted the improvement of membrane production in the presence of light, while also exhibiting a high degree of operational efficiency.

用于直接接触膜蒸馏的嵌入碳纳米管的聚砜膜的光热效率
膜蒸馏(MD)是一种非常有前景的高盐分海水淡化方法。然而,该技术面临的一个主要挑战是能耗高,这是因为需要加热含盐进料溶液。因此,本研究旨在将多壁碳纳米管(MWCNTs)加入聚砜(PSF)基质中,以制造复合光热 MD 膜。这些膜无需外部能源即可独立运行。在 PSF 浇注溶液中添加了 0.5%至 1.5%(按重量计)的不同数量的 MWCNT。这样就制成了具有更好光热特性的复合膜。使用扫描电子显微镜(SEM)、傅里叶变换红外光谱、热重分析和接触角测量对 PSF 和 PSF/MWCNTs 复合膜进行了分析。结果发现,产生最高光热效率的 MWCNTs 浓度为 1%(按重量计)。使用光热膜蒸馏(PMD)装置对膜进行了评估,研究了操作条件和参数。当膜放置在距离 200 W 光源 10 厘米处时,MWCNT 的存在使膜的表面温度升高至 67 °C。此外,加入 MWCNTs 后,接触角测量值从 80° 上升到 112°,液体进入压力 (LEP) 从 25.5 psi 提高到 52 psi。此外,它还对改善光照下的膜生产产生了重大影响,同时还表现出很高的运行效率。
