A lot of freshwater is needed daily to meet society's domestic, agriculture, and industrial demands. Desalination, creating freshwater from seawater, continues to grow in popularity as a way to supplement the Earth's natural freshwater resources.

However, salty seawater cannot be taken from the sea and sent directly to a desalination system's specialized equipment. It must first undergo pretreatment upstream to prepare it for processing through the specific desalination technology employed at the facility. Similarly, before the produced freshwater can be distributed for use in society, it must undergo post-treatment to prepare it for its intended use.

The Desalination: Pre- and Post-Treatment of Water training course discusses concerns with bringing seawater into a desalination system for processing. It also describes specific pre-and post-treatment applications common to processing water through reverse osmosis and thermal distillation desalination systems.

This online course is part of the Water Treatment training series.
