SAN LEANDRO, Calif.—May 19, 2015— Energy Recovery Inc.

For this project, Energy Recovery is partnering with Sidem, a global desalination leader headquartered in France.

Sidem will use Energy Recovery’s PX-Q300 Pressure Exchanger devices for the plant in Sur in the Ash Sharqiyah Region of northeastern Oman.

Having successfully deployed our PX Pressure Exchanger technology into another major project with Sidem, we continue to act as the preferred supplier of energy recovery solutions with the Q-series of our PX devices. This project has experienced delays over the past year, and we feel this shipment is an indicator of a strengthening global desalination market, the sustainability of which will lend to our continued penetration into emerging markets.”
