Water Treatment Design Course - Self-Study
The Water Treatment Design Course is a self-paced training opportunity for technical in-office staff, technical support staff, engineers and others to learn about water contaminants and treatment solutions. The course addresses contamination behavior, drinking water regulations, POU/POE treatment technologies and their application and sizing.
The course is a pre-requisite for the Certified Treatment Designer title.
The first three of four modules may also be completed as instructor-led courses in the CWS program. Please check the Education page at wqa.org for upcoming classes and make sure to select the CTD-path options when registering.
