摘要
膜污染、膜结垢和膜润湿现象的发生是制约膜蒸馏(MD)实现规模化工业应用的主要阻碍.深刻揭示这些现象的演化机制在很大程度上需要推动新型表征方法的探索.光学相干断层成像技术(OCT)是一种新兴的、能够对各种膜分离过程进行非侵入性表征的技术.本综述在简要介绍OCT表征相关原理的基础上,旨在阐明如何利用基于OCT的技术对MD过程进行定性(例如污染层的可视化)和定量(例如污染层的原位结构测量)分析.除了评价应用OC T研究MD过程的优缺点外,本综述也为在水资源再生以及其他分离领域中设计高效的MD系统提供了实用和理论依据.
Abstract
Applications of membrane distillation(MD)are hindered primarily owing to the occurrence of membrane fouling,scaling,and wetting;revealing the mechanisms underlying these negative phenomena is strongly dependent on the exploration of novel characterization methods.Optical coherent tomography(OCT)is an emerging technique that enables a non-intrusive characterization for various membrane processes.When introducing the relevant principle of OCT,this review is aimed at elucidating how the OCT-based characterization was exploited to analyze MD processes in both qualitative(e.g.,visualization of the fouling layer)and quantitative(e.g.,in-situ structural measurement of the fouling layer)ways.In addition to assessing the pros and cons of applying OCT to the studies on MD,practical and theoretical implications are discussed to shed light on the design of high efficiency MD systems for water reclamation and other separations.
