Description
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!
Who this course is for
Companies that supply or install softeners, ion exchange systems, softners and demineralizers. Students interested in learning in depth the mechanism of ion exchange and the four main types of resins on the market.
