Spain's Cadagua has chosen PX^® energy-recovery technology for its refit contract for the Valdelentisco desalination plant in Murcia, Spain.

Energy Recovery Inc (ERI) is supplying the units for phase 1 of the project which involves retrofitting two reverse-osmosis trains in the 140,000 m³/d plant owned by Acuamed.

By retrofitting and upgrading with the latest in desalination energy-recovery technologies, plants and municipalities can save money and increase efficiencies, says ERI. In Spain, ERI technology has been chosen in a majority of 2012-13 retrofit operations and has saved customers 1.5 billion kWh and more than US$ 158 million per year.

"Even during hard economic times, we knew investing in ERI's solutions would give us the best return on our investment," explains Eva Muñoz, Cadagua project manager. "The cost savings we are expecting to achieve will be vital to the plant's ability to remain online, and to the development of fresh water production for our country."
