Installer Training
This course addresses best practices, treatment equipment operation, premise plumbing systems, safe drains, pressure loss, and installation procedures. Successfully completing this one course qualifies you to take the Certified Installers exam.
Session – “RO Part 2/UV”
This session explores the use of cartridge filters and ultraviolet (UV) disinfection systems in residential water treatment. Participants will learn about filter types, flow patterns, sizing, and installation tips, along with how UV systems deactivate microorganisms and what conditions are required for effective operation. Ideal for those seeking practical guidance on improving water quality and system reliability.
Session A – 8 a.m. ET (7 a.m. CT)
Tuesday, Oct. 28
Session B –10 a.m. ET (9 a.m. CT)
Thursday, Oct. 30
Assessing Water Quality Problems
WQA’s introductory Instructor-led course on POU/POE Water Treatment is the first step toward the CWS/CWR/CST/CTD certifications. It walks the learner through identifying aesthetic problems, onsite testing, interpreting water analyses for aesthetic contaminants, and drinking water regulations.
Session – “Selecting Tests for Drinking Water Contaminants”
Learn how to identify which water contaminants to test for and how to interpret lab results effectively. This module walks through categories like microorganisms, inorganics, organics, radionuclides, and PFAS, and discusses sampling techniques, regulatory standards, and local water quality concerns. Perfect for professionals helping customers make informed decisions about water testing.
Session A – 11 a.m. ET (10 a.m. CT)
Wednesday, Oct. 29
Session B – 8 a.m. ET (7 a.m. CT)
Thursday, Oct. 30
Application & Sizing of POU/POE Treatment for Aesthetic Contaminants
This course moves from identifying problems into how to select and correctly size treatment equipment for aesthetic contaminants. It is the final course in the CWR coursework and the second in a series for the CWS/CST/CTD titles.
Session – “Overview of Membrane Technologies”
Dive into membrane-based water treatment technologies including microfiltration, ultrafiltration, nanofiltration, and reverse osmosis. This session explains how these systems work, what contaminants they remove, and how pressure and membrane design affect performance. Great for those looking to understand advanced filtration methods and system design.
Session A – noon ET (11 a.m. CT)
Tuesday, Oct. 28
Session B – 9 a.m. ET (8 a.m. CT)
