This presentation serves as an introductory guide to water chemistry for point-of-use and point-of-entry treatment of aesthetic contaminants. It walks technicians through a three-step decision tree—identifying suspended, gaseous, or dissolved constituents—and then dives into the behavior of ionic, polar, and non-polar dissolved substances. Foundational concepts such as ion definition, conductivity measurement, periodic trends, and electron configuration are highlighted to prepare professionals for real-world challenges like removing lithium from well water.
Session A – 12 p.m. ET (11 a.m. CT)
Tuesday, Aug. 26
Session B –9 a.m. ET (8 a.m. CT)
Wednesday, Aug. 27
Water Chemistry Part 2 (0.1 CPD)
(from the “Application & Sizing of POU/POE Treatment for Aesthetic Contaminants” course)
Water Chemistry Part 2 extends the water‐chemistry framework to polyatomic ions, solubility rules, hardness definitions, and the fundamentals of ion exchange and chemical equilibria. It equips technicians with practical insight into why contaminants behave the way they do and how factors like resin affinity, kinetics, and pH control treatment performance.
