Freshwater is essential for industrial, agricultural, and domestic purposes. From drinking water to crop irrigation to plant makeup water, an abundance of freshwater remains a critical necessity for society. But as the world's population continues to rise, growing demands on Earth's natural freshwater supplies cannot be sustained.

However, the availability of saline water sources, such as seawater and brackish water, added to the growing number of desalination plants, can be a reliable supplement to, and even substitute for, freshwater resources.

The Introduction to Desalination training course defines desalination and discusses its importance to society. It describes membrane and thermal technologies used for the desalination process. It also explains the purpose of pre- and post-treatment systems. This online course focuses on:

• Introduction to desalination
• Pre-treatment process
• Desalination technologies
• Post-treatment process

Introduction to Desalination is part of the Water Treatment training series.
