Abstract

The paper presents two methods for identifying microstructural heterogeneities on the surface of OFAM-K and OPMN-P nanofiltration membranes. Optical microscopy in combination with the AutoCad 2016 computer-aided design system and standard Microsoft Excel 2010 tools allows one to investigate microstructural heterogeneities of initial samples of OPMN-P and OFAM-K nanofiltration membranes. A method that enables the automated calculation of the average diameter of the fouling of semi-permeable membranes and the fouling coefficient of porous bodies is also developed. Using the capabilities of the Matlab 2017 software package, the application of modern tools to accomplish the set goal of the work is shown. Practical implementation of the method is exemplified by the nanofiltration process with semi-permeable polymer membranes of OFAM-K and OPMN-P types. The automated method combining optical microscopy studies, Otsu image processing, and software implementation in Matlab 2017 and optical microscopy in combination with the AutoCad 2016 computer-aided design system and standard Microsoft Excel 2010 tools, which more accurately reveals the structural heterogeneities of OFAM-K and OPMN-P nanofiltration membranes, are compared.

OFAM-K 和 OPMN-P 纳滤膜表面微观结构异质性的鉴定

摘要

本文提出了两种用于识别 OFAM-K 和 OPMN-P 纳滤膜表面微观结构异质性的方法。光学显微镜与 AutoCad 2016 计算机辅助设计系统和标准 Microsoft Excel 2010 工具相结合，可以研究 OPMN-P 和 OFAM-K 纳滤膜初始样品的微观结构异质性。还开发了一种能够自动计算半透膜结垢平均直径和多孔体结垢系数的方法。使用 Matlab 2017 软件包的功能，展示了现代工具的应用以完成工作的既定目标。该方法的实际实施以 OFAM-K 和 OPMN-P 类型的半透聚合物膜的纳滤过程为例。
