**课程名称：** 离子交换树脂在水处理中的应用 - 2025版 **课程概述：** 本课程由化学工程师 Carlos Maffessoni 主讲，旨在深入讲解离子交换树脂在人类生活用水及工业用水处理中的应用。课程在前一版本的基础上进行了全面升级和扩充，在图像和音质方面均有显著提升。已有近80名学生通过其他平台完成了学习。 课程内容涵盖广泛，从离子交换树脂的历史沿革到深入的理论基础，包括分离系数概念、四种市售树脂类型的配置，以及工程师和技术人员最关心的设备选型项目（包括手动算法和软件应用）。 **课程结构（七个章节）：** 1. **基础概念：** 介绍历史回顾、树脂的化学结构与类型、单位、可去除的水污染物，以及简易软化设备选型计算。 2. **概念扩展：** 深入解析“服务流速”、“线流速”、“选择性”和“交联度”等概念。重点阐述选择性和分离系数理论，解释为何简单的计算可能因含更具选择性的污染物而产生较大的选型误差。介绍1975年Anderson提出的尺寸计算方法。 3. **树脂的“敌人”与容量：** 探讨导致树脂损坏的因素、优先流道（或沟流）现象，以及WAC型树脂在碱度去除中的应用。重点分析树脂的理论/标称容量与实际/运行容量之间的关系及其对选型计算（尤其是手动计算）的影响。 4. **硝酸盐去除：** 详细介绍硝酸盐去除技术，分析硫酸盐等其他污染物对阴离子交换树脂硝酸盐去除能力的影响。将运用Anderson技术并进行案例研究。 5. **再生阶段：** 全面讲解再生过程，包括适宜的再生用水、再生剂的类型与浓度，并提供详细的实践计算，帮助用户正确调整工艺。 6. **进阶议题：** 讨论在其他课程和文献中较少涉及的主题，包括软化和去离子系统的液压细节、混合床、单位换算、当前市场状况，以及软化过程的局限性（例如去除一个离子会引入另一个）。通过显微镜图像和视频展示树脂的形态。 7. **系统项目与选型：** 专注于离子交换系统项目的实际应用，包括特定水质和流量下所需树脂量的选型。涵盖实际项目的液压细节、脱气在去离子项目中的影响、不同品牌同类型树脂的性能对比。此外，还将讨论碱度去除以及四种树脂类型在去离子系统中的各种容器组合等。 **目标学员：** 本课程理论与实践兼备，适合工程师、技术人员、学生、教师以及直接或间接从事离子交换树脂、软化器和去离子系统（包括饮用水和工业用水处理）的专业人士。
Hello!My name is Carlos Maffessoni. I am a chemical engineer at IG Engenharia, and I am pleased to be here to present the Ion Exchange Resins course, which aims to treat water for human or industrial consumption.The success of the course launched in 2021 motivated us to expand and review all topics, which is even better and more complete now. The presentation has improved both image and sound quality. We counted around 80 students until February/2025 on another platform.The training is extensive and covers everything from historical aspects of ion exchange resins to a very detailed theoretical basis - including the concept of separation factors, the various configurations of the four types of resins available on the market, and what engineers and technicians are most looking for: sizing projects, manually and with software.The course is divided into seven chapters, and we will briefly comment on each of them.In the first chapter, we will cover the basic concepts necessary to understand this technology. Main topics covered: historical review, chemical structure and types of resins, units, water contaminants that can be removed with this technology, and the first simple examples of softener sizing calculations.In the second chapter, the concepts are expanded, and we will see what "Service Flow Rate", "Linear Flowrate", "Selectivity" and "Cross-linking" represent. The theory of Selectivity and Separation Factors will also be presented, which explains why very simplified calculations can result in large sizing errors, simply because the water contains a more selective contaminant than the species to be removed. Finally, we will learn how to calculate dimensional systems using another calculation method, presented by Anderson in 1975.In the third chapter, the enemies of resins will be presented and what type of damage they cause to them, as well as "Preferred Paths" or "Channeling" and the applicability of WAC-type resins for alkalinity removal.The main theme of the chapter is the relation between the theoretical or nominal capacities and the real or operational capacity of the resins, and how much this affects the sizing calculation, especially the manual one.Nitrate removal will be extensively detailed in chapter four, as it is an important contaminant rarely detailed in the literature and even less in sizing software. We will see how much a particular contaminant, in this case sulfate, alters the nitrate removal capacity of anionic resins. Anderson's technique will be used, and a study case will be carried out.In the fifth chapter, the regeneration stage will be detailed, presenting everything from water suitable for regeneration, through types and concentrations of regenerants, and a practical calculation will be presented containing all the information necessary to adjust your process correctly.Subjects little or never covered in courses and literature will be mentioned in chapter six. Hydraulic details of softening and demineralization systems, mixed beds, unit conversion, and even the current market situation will be presented. Limitation of softening will also be taught, because when you remove one ion, you add another, and this needs to be considered. The resins will also be presented as they are, with images and films obtained through microscope observations.Finally, in the chapter 7, the most desired subject for engineers, technicians, and those on the front line of projects and assembly of ion exchange systems, but which can also be of great use for students and master's students: ion exchange system projects, contemplating the sizing of the amount of resins required for a given type of water at a given flow rate. Hydraulic details of real projects. The influence of the degassing stage on demineralization projects. Comparison of results using similar resins from different brands. Alkalinity removal. The various combinations of vessels for demineralization, using the four types of resins available on the market, among other important issues that rarely are commented on even in specialized literature.A complete theoretical-practical training, useful for engineers, technicians, students, teachers, and people who work directly or indirectly with ion exchange resins, softeners, and demineralization systems, both for water intended for human consumption and for industrial use.Thank you very much, success!
