An Introduction to Water Desalination

COURSE NO: H04-002
An Introduction to Water Desalination
Course Highlights

This online engineering PDH course will introduce you to water desalination technologies, processes and methods.  You will learn the importance of site and water source selection.  You will be introduced to an approach for selecting the appropriate desalination technology and process. You will learn about distillation/condensation techniques, membrane techniques and ion exchange techniques. You will find out how to develop process concepts, evaluate their utility, and move forward into preliminary design for projects and sites where water desalination is an operational requirement.


This 4 PDH online course is intended for engineers and other design and construction professionals interested in gaining an understanding of the technologies, processes and techniques for treating saline water, such as from the sea, to provide potable or suitable process water to meet the operational requirements of facilities and activities.
