Returning to the podcast to discuss water desalination is Mark Holtzapple. Mark is a Professor of Chemical Engineering at Texas A&M University where he researches technologies that improve sustainability.

With close to 30 years of experience as a researcher, Mark is constantly finding new ways to turn waste into useful products. So what's his take on obtaining fresh water from saltwater?

In this episode, you will learn about:

• What desalination is, and how Mark got started working with it.
• Techniques used to desalinate water, and how they have evolved over the years.
• How reverse osmosis contributes to water desalination.
• What vapor compression technology is, and why this may be the future of energy-efficient water desalination.

Imagine a world where freshwater is as plentiful as seawater… With the work that researchers like Mark Holtzapple are doing, this idea may be more realistic than you may think!
