Water scarcity is becoming one of the defining global challenges of the 21st century. As demand for reliable freshwater increases, desalination is playing a growing role in national water security. But historically, desalination has been extremely energy-intensive.
In this interview, Rodney Clemente, Senior Vice President of Desalination at Energy Recovery, explains how the company’s PX Pressure Exchanger technology has helped transform the economics of desalination. Energy Recovery has recently launched the PX Q650, the latest generation of its flagship pressure exchanger, designed for the next generation of large-scale desalination plants.
We discuss:
- Why desalination used to be so energy-intensive
- How the PX Pressure Exchanger captures wasted energy
- Why the technology can reach 99% efficiency
- The role desalination will play in global water security
- How the new PX Q650 supports the world’s largest desalination plants
As water scarcity grows worldwide, innovations in efficiency and infrastructure will play a critical role in delivering sustainable freshwater supplies.
