课程名称：离子交换系统设计（水处理） 课程概述：本课程面向希望了解离子交换系统的工程师，旨在教授离子交换系统在去除水中硬度和降低总溶解固体（TDS）方面的应用。课程结束时，学员将能定义树脂并进行分类，理解树脂的使用，并根据废水特点决定离子交换系统的处理方案。此外，课程还涵盖离子交换树脂的制备，讲解不同结构和功能基团的树脂类型。学员将了解离子交换系统的再生方法，并掌握设计交换容量的定义及树脂的交换容量。课程讨论了pK值的概念，以帮助理解为何某些酸是弱酸而某些酸是强酸。同时提供了过程流程图和过程仪器图，以便理解此过程中的机械设备和仪器。本课程还涵盖了计算树脂体积、再生体积、反洗过程中的水废水流量等公式。课程结束后，学员将能够全面设计一个离子交换系统。
This course is targeted at engineers who would like to know about the ion exchange system. The ion exchange system is used to remove hardness and reduce Total Dissolved solids. At the end of this course, one would be able to define resin and classify resins. Also, the usage of resin would be explained and one would be able to decide the treatment scheme of the ion exchange system based on the wastewater characteristics. Preparation of the ion exchange resins is also covered in this course. The different types of resins based on both structure and functional groups are explained. The two ways in which these ion exchange systems can be regenerated are also explained. Design exchange capacity would be defined and the exchange capacity of the resins is also given. Also, concepts like pK values are discussed in order to understand why certain acids are weak and certain acids are strong. The process flow diagram and the process instrumentation diagrams are provided to understand the mechanical equipment and the instruments involved in this process. The formulae to calculate the resin volume, regenerate volume, the flow of water wasted during backwash, etc. are covered in this course. At the end of this course, one would be able to design an ion exchange system completely.
