Energy Recovery Inc PX(TM) Technology to Significantly Reduce Lifecycle
Costs at Massive Desalination Plant in Qingdao, China


Isobaric Energy Recovery Devices to Substantially Decrease Energy Consumption and Operational Costs of 100,000 m3 (26.4 Million Gallons) Seawater Desalination Plant to Serve More Than 500,000 People

SAN LEANDRO, Calif., Oct 26, 2010 (BUSINESS WIRE) --

Energy Recovery Inc (NASDAQ: ERII), a leader in the design and development of energy recovery devices for desalination, today announced that its industry-leading PX Pressure Exchanger(TM) (PX(TM)) isobaric energy recovery devices will be implemented at the large seawater reverse osmosis (SWRO) desalination facility to be built by Befesa in Qingdao, China.

Energy Recovery's PX devices will significantly reduce the energy consumed by the reverse osmosis (RO) process in the Qingdao plant by enabling cost-effective, energy-efficient delivery of 100,000 m3 (26.4 million gallons) of potable water per day to more than 500,000 people. The Qingdao plant is Befesa's seventh massive RO plant to incorporate Energy Recovery's technology, as PX devices are currently implemented at facilities in Chennai, India, Bajo Almanzora, Spain, and four major plants in Algeria.

"While desalination represents a long-term solution to global water scarcity, the water produced must be affordable for it to be a viable, sustainable option. That is why Befesa continues to work with Energy Recovery Inc to implement its innovative PX devices to significantly reduce the lifecycle costs of the desalination process," said Carlos Cosin, international director with Befesa. "We have worked with Energy Recovery on several global mega-projects, and continue to be impressed with the reliability, efficiency and overall performance of its PX technology. We anticipate similar success in the Qingdao facility and look forward to continuing our partnership with Energy Recovery to meet the increasing worldwide demand for desalination."

The Qingdao desalination plant is expected to be operational by the end of 2012, and will save more than 2,000 kW of energy and offset more than 10,000 tons of CO2 annually with Energy Recovery's PX devices. It will be the second large-scale potable water facility in China to include PX technology. Energy Recovery's solutions are in the majority of small to medium-sized RO plants throughout China.

"Befesa has constructed many impressive RO desalination facilities throughout the world, and Energy Recovery's PX devices continue to help these plants affordably deliver potable water," said Borja Blanco, executive vice president of Energy Recovery Inc. "We look forward to working with Befesa on the Qingdao project as part of our continued success in China as the country ramps up construction of RO desalination facilities."

ERI's PX devices operate at up to 98 percent efficiency and reduce the energy consumption of SWRO systems by up to 60 percent, making desalination a cost-effective solution for clean water supply. PX devices also reduce the carbon footprint of desalination, saving more than 970 MW of energy and reducing CO2 emissions by more than 5.2 million tons per year worldwide. More than 8,600 PX devices are currently deployed or under contract to be installed at desalination plants around the globe.
