What Do People Still Get Wrong About Desalination Technology? | Salty Water Podcast with Eric Jankel

What Do People Still Get Wrong About Desalination Technology? Lessons from 40 Years Inside Desalination and Membrane Technology Desalination is often misunderstood. It is called too expensive, too energy intensive, or unrealistic at scale. But much of what people believe about desalination technology is outdated, incomplete, or based on early failures rather than decades of real-world progress. In this episode of the Salty Water Podcast with Eric Jankel, Eric sits down with John Tonner, Executive Director of the American Membrane Technology Association and an XPRIZE Water Scarcity Judge, for a wide-ranging, career-spanning conversation about what people still get wrong about desalination technology and why those misconceptions persist. With more than 40 years in the industry, John Tonner has worked across thermal desalination, seawater reverse osmosis, energy recovery systems, international water consulting, and large-scale project development. His career spans early, risky desalination plants, the evolution of membrane technology, major breakthroughs in energy recovery, and today’s global push to address water scarcity through innovation and smarter delivery models. This episode goes beyond theory. It explores what actually worked, what failed, and what lessons engineers, policymakers, utilities, and the public still need to understand about desalination technology today. If you care about water security, infrastructure, energy use, public health, or the future of clean drinking water, this episode of the Salty Water Podcast with Eric Jankel offers rare, experience-driven insight you will not find in academic papers alone. ⏱️ Episode Timestamps (Approximate, topic-based) 00:00 – Welcome to the Salty Water Podcast with Eric Jankel 02:30 – John Tonner’s unconventional entry into desalination 07:15 – Early desalination plants and what went wrong 13:40 – Thermal vs reverse osmosis, lessons learned 21:10 – Energy recovery myths and real-world breakthroughs 30:45 – Why desalination is still misunderstood today 38:20 – Cross-border water projects and regulatory challenges 47:30 – XPRIZE Water Scarcity competition and future innovation 56:10 – What the next generation of water professionals should know 01:02:30 – Final reflections on desalination, water scarcity, and progress 🔑 Key Takeaways Why desalination’s reputation does not match its real-world performance How early technical and operational mistakes shaped public perception The role of membrane technology in water reuse and potable supply Why energy costs are often misunderstood in desalination discussions What needs to change in project delivery, regulation, and communication 🔍 Search Terms & Topics desalination technology, desalination myths, water scarcity solutions, membrane technology, reverse osmosis, thermal desalination, water innovation, water infrastructure, potable reuse, water energy nexus, global water supply, water security, public health water systems, desalination costs, desalination energy use, podcast about water, water technology podcast Parents, communities, and policymakers often ask how water quality affects health, long-term sustainability, and family well-being.
