Energy Recovery Technology to Help Deliver Water Security to One Million People Across Saudi Arabia's Mecca, Al-Baha, and Asir Regions

Key Terms

pressure exchanger technical

A pressure exchanger is a mechanical device that transfers the force from a high-pressure fluid stream to a low-pressure stream so the second stream gains pressure without needing extra energy input — think of it as a hands-on way to pass along momentum instead of re-creating it. Investors care because it sharply cuts energy use and operating costs in high-pressure systems like water desalination and industrial filtration, improving project economics, margins, and the competitiveness of companies that make or use the technology.

reverse osmosis technical

A water-cleaning process that uses pressure to force water through a very fine membrane, leaving salts, minerals and many contaminants behind — like pushing juice through an extremely tight sieve so only pure liquid passes. Investors care because reverse osmosis is a core technology for desalination, industrial water recycling and many manufacturing processes, driving capital spending, recurring service revenue and regulatory or environmental risk and opportunity for companies involved.

• The flagship project advances Saudi Arabia's Vision 2030 water security goals for some of the Kingdom's most strategically important regions.
• Energy Recovery's installed base and contracted capacity across Saudi Arabia supports over 11 million cubic meters per day of fresh water production.

SAN LEANDRO, Calif.--(BUSINESS WIRE)-- Energy Recovery (Nasdaq: ERII), a global leader in energy-efficient technology enabling affordable, reliable water and reduced emissions, today announced a contract to supply its PX® Pressure Exchanger® energy recovery devices to a new flagship seawater reverse osmosis desalination plant under Saudi Arabia's Vision 2030 program. When complete, the plant will deliver affordable, drought-proof water to approximately one million people across the Kingdom's Mecca, Al-Baha, and Asir regions.

Saudi Arabia relies on desalination for more than 70 percent of its potable water supply and has no permanent rivers or lakes, making energy-efficient desalination capacity central to the Kingdom's water security. Mecca, one of the region's most strategically and culturally important cities, drew over 1.5 million pilgrims for Hajj earlier this year, underscoring the importance of a reliable, affordable water supply for the surrounding area.

Energy Recovery's PX devices will operate within the plant’s reverse osmosis process, reducing the energy required to produce fresh water from seawater.

"Saudi Arabia continues to advance an impressive portfolio of water infrastructure to meet rising demand, and this contract reflects the trust the region places in Energy Recovery's technology," said Rodney Clemente, Senior Vice President of Water at Energy Recovery. "Timelines across the region are still shifting as customers adapt to today's environment, but the Kingdom is executing steadily against its Vision 2030 water security goals, and we're proud to be a long-term partner in that effort for a region as important as Mecca."

Energy Recovery's PX devices deliver up to 99 percent efficiency, reducing the energy consumption in seawater desalination by up to 60 percent. With a single moving part and a 30-year design life, the PX is deployed across major desalination plants worldwide.
