• Global water treatment company intends to use energy recovery devices from ERI in its first seawater desalination vessel

SAN LEANDRO, CA, May 19, 2009 -- Energy Recovery Inc., a leader in the design and development of energy recovery devices for desalination, announced that Water Standard, a global vessel-based water desalination company, plans to use the PX Pressure Exchanger™ (PX™) device in its first Seawater Desalination Vessel (SDV). Water Standard builds and operates vessels that deliver desalinated water to clients onshore and to the offshore energy industry in response to the world's growing water needs.

"Water production cost is a key metric to the success of our initiative and ERI is a great partner to help improve desalination economics. ERI's PX technology, which is capable of improving desalination energy costs by up to 60%, is field-proven and reliable."

By integrating proven reverse osmosis water treatment technology and proprietary water intake and discharge systems in its Seawater Desalination Vessel design, Water Standard provides a mobile, cost-effective and environmentally responsible solution to provide water where needed and address the severe water shortage that is challenging the world.

Water Standard's Seawater Desalination Vessel (SDV) can produce from 20,000m3 to 200,000m3 per day (roughly 5 MGD to 50 MGD). Seawater Desalination Vessels can be based on any floating water platform, including ships or barges, depending on the water requirements in the affected region.

"Water Standard is leading the efforts in vessel-based desalination and we're proud to have been selected as a strategic partner," said G.G. Pique, ERI's president and chief executive officer. "The SDV initiative is a flexible and environmentally-responsible way to provide drinking water to people in need. ERI's PX devices can make that water supply more affordable."

Seawater desalination refers to the process of making drinking water from ocean water. The salts and other impurities are removed through a process known as reverse osmosis (RO) membrane filtration, a proven method that produces some of the highest quality drinking water available anywhere. ERI estimates that its PX technology will save Water Standard 34 MW and improve the carbon footprint of its vessels by 142,000 tons of CO2 per year.

Energy Recovery Inc. designs and develops energy recovery devices that help make desalination affordable by significantly reducing energy consumption.
