This review for the first time aims to investigate the effect of silanization on the ceramic membrane distillation (CMD) as a promising thermally driven separation process. In this regard, the effects of three main factors, namely silane concentration, silane duration, and time as well as the important operating parameters on the process were studied. At the end of this work, future challenges and recommendations in the CMD have also been addressed. The literatures have confirmed that silanization of the CM surface, causes significant changes in the membrane structure in terms of hydrophobicity (water contact angle > 130°), creating different functional groups on the surface and improving the efficiency of the process. The results of previous research woks indicate that the best conditions for the silanization process are possible at silanization time (about 72 h), the number of grafting cycles (1–5 times), and silane concentration (2 or 10 wt%). Concluding the results of various studies shows that the efficiency of the MD for desalination process was high (removal > 98%) under certain conditions (feed input temperature: 70–80 °C and flow rate of 0.3–400 L/h).

硅烷化对陶瓷膜蒸馏 (CMD) 影响的批判性评论:性能、操作因素和表征

本综述首次旨在研究硅烷化对陶瓷膜蒸馏(CMD)作为一种有前途的热驱动分离过程的影响。在此方面,研究了硅烷浓度、硅烷持续时间和时间这三个主要因素以及重要操作参数对该过程的影响。在这项工作结束时,CMD 中未来的挑战和建议也得到了解决。文献证实,CM表面的硅烷化会导致膜结构在疏水性方面发生显着变化(水接触角> 130°),在表面上产生不同的官能团并提高工艺效率。前期研究结果表明,硅烷化过程的最佳条件可能是硅烷化时间(约72小时)、接枝循环次数(1-5次)和硅烷浓度(2或10wt%)。各种研究结果表明,在一定条件下(进料温度:70-80°C,流量0.3-400 L/h),MD 海水淡化过程的效率很高(去除率 > 98%)。
