Energy Recovery and Seawater Desalination

New 120,000 m3/day (31.7 million US gallons per day) SWRO Plant in Algeria

SAN LEANDRO, Calif.--(BUSINESS WIRE)--Dec. 11, 2008--Energy Recovery, Inc. ("ERI") (NASDAQ:ERII), a global leader of ultra-high-efficiency energy recovery products and technology for desalination, announces another large-scale energy recovery contract for seawater reverse osmosis (SWRO) desalination in Algeria. The Fouka SWRO Desalination project is designed to produce 120,000 cubic meters per day (m3/day, 31.7 million US gallons per day (MGD)). It is scheduled to begin operation in early 2010.

The Fouka SWRO Desalination Plant will be located in Tipasa near the city of El Jazair on Algeria's northern coast. The project is being developed by Acciona Agua of Spain and SNC Lavalin International of Canada on a 25 year build, own and operate (BOO) contract basis. The 138 ERI PX-220 energy recovery devices are expected to save nearly 13 MW of energy or over 113,000 MWh per year. In total, ERI is helping to produce over 1.5 million m3/day (396 MGD) of drinking water for the Algerian region alone, saving an estimated 440 MW of energy on an ongoing basis.

Recently, Acciona Agua as part of a consortium also contracted ERI's PX technology for the Tordera desalination plant near Barcelona. Here, older turbine technology was replaced with advanced, more efficient PX Pressure Exchanger devices to save energy and increase plant production capacity.

Borja Blanco, ERI's GM and VP, Mega Projects Division, stated, "This contract award, along with Tlemcen Souk Tleta, consolidate ERI as the preferred supplier of energy recovery devices in the Mediterranean basin. Eight major desalination projects have been awarded by different contractors in Algeria so far, and all of them with ERI PX technology. Using our energy recovery solution allows the Algerian government to provide affordable water to their constituents."

Large Scale Seawater Desalination Project to Produce 200,000 Cubic Meters Per Day (52.8 Million US Gallons) of Fresh Water

SAN LEANDRO, Calif.--(BUSINESS WIRE)--Dec. 9, 2008--Energy Recovery, Inc. ("ERI") (NASDAQ:ERII), a global leader of ultra-high-efficiency energy recovery products and technology for desalination, announces the award of another large-scale energy recovery contract for seawater reverse osmosis (SWRO) desalination in Algeria. The Souk Tleta SWRO Desalination Plant, located in Tlemcen in Northwestern Algeria, will have a total capacity of 200,000 cubic meters per day (m3/day) (52.8 million US gallons per day (MGD)). The plant is slated to begin operation in the first half of 2010.

The Souk Tleta plant is being built by the Singapore-based company Hyflux on a 25-year build, own, operate and transfer (BOOT) basis. It will provide desalinated seawater to the Algerian Energy Company (AEC), the state-owned national water entity of Algeria. Under the contract, ERI will supply the plant with 260 PX-220 energy recovery devices that will save an estimated 21 MW of energy.

Earlier this year, Hyflux also contracted ERI's PX technology for the 100,000 m3/day (26.4 MGD) Tianjin desalination project. This is the largest desalination project contracted in China to date.

Borja Blanco, ERI's GM and VP, Mega Projects Division, stated, "This is a significant award for us in that we are able to provide our client with maximum energy savings which results in the lowest life-cycle costs. Our technical staff works closely with all involved to ensure that the project achieves or surpasses the energy recovery expectations."
