Case Studies
ERI clients are saving more than $550 million per year in energy costs. With more than 10,000 PX devices and turbochargers in the market, ERI is helping support the worldwide production of water for industries and human consumption.
Al Shuaibah Seawater Desalination Plant
Seawater desalination using the reverse osmosis process is now the least expensive, most environmentally friendly desalination technology available today. Advancements in membrane technology, as well as improvements in pump efficiency, have helped make seawater reverse osmosis (SWRO) a viable alternative to traditional thermal methods. However, the most significant advancement in recent years—making membrane-based desalination a truly cost-effective technology—has been the introduction of isobaric energy recovery systems, such as the Energy Recovery, Inc. (ERI) PX™ Pressure Exchanger (PX™) device.
Cabo Cope Desalination Plant, Murcia, Spain
Drinking water to residents and water supply for farm usage reached critically low levels. Moreover, the high construction costs for new desalination plants threatened to increase the cost of water supply. Farmers, businesses and residents did not want to pay more for using desalinated water.
Cabo San Lucas Desalination Plant, Mexico
The Cabo San Lucas Desalination Plant provides municipal drinking water to approximately 40,000 local residents.
Dalian Petrochemical Plant, China
At 5,000 m3/day, the Dalian Petrochemical Company SWRO plant began operation in November 2003 as one of the largest SWRO installations in Asia.
Dhekelia Desalination Plant, Cyprus
The Dhekelia Plant was the first large scale (10,000 m3/day per train) to employ ERI PX technology which was implemented as a retrofit for the original Francis turbines energy recovery solution.
Ghalilah Desalination Plant, UAE
The Ghalilah plant was designed and built by Fisia Italimpianti. Among plants that use ERI PX Pressure Exchangers, this is the largest SWRO plant in the Gulf.
Hurghada Desalination Plant, Egypt
Ridgewood decided to retrofit its plant, which previously included a turbo charger energy recovery device with an Energy Recovery, Inc. (ERI) PX technology solution. Currently, plant capacity is at 1,500 m3/day.
Maspalomas Desalination Plant, Spain
Since 2006, ELMASA has retrofitted the EDR plant with PX Pressure Exchanger (PX) technology to provide a seawater reverse osmosis solution that has significantly reduced energy consumption and CO2 production by the plant.
Perth Desalination Plant, Australia
To reduce energy and overall costs, ERI’s industry-standard PX technology was selected by the Degrémont Multiplex Joint Venture as the advanced energy recovery solution for the project. The first of 12 trains of the Perth SWRO Plant started producing fresh water in November 2006.
Regents de Mazarron Desalination Plant, Spain
In 2001, the Comunidad de Regantes de Mazarron Desaladora "Virgen del Milagro" Plant decided to reduce their power consumption by retrofitting their installed energy recovery device with the more efficient PX Pressure Exchanger ® Technology (PX®).
Sharm El-Sheikh Desalination Plant, Egypt
ERI’s PX technology allowed Intech to increase production to three times more than that of the original process. Moreover, capacity was increased within the same footprint, saving civil work, time and money.
YuHuan Desalination Plant, China
The plant, built by Beijing CNC Technology, Inc. will supply process water to new electrical power stations. The OEM’s decision to use ERI®’s PX Pressure Exchanger® Technology (PX®) for the 36,000 m3/day YuHuan desalination plant will prepare the Country for its 2008 Olympics.
