Algerian Desalination Capacity Increases With ERI PX Technology

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