With a growing metropolitan population of over 8 million people, Chennai is the fourth largest population center in India after Mumbai, Delhi, and Kolkata. Historically dependent upon limited water resources, the people of Chennai must pay high costs to transport water. Meanwhile, the lakes that supply the city’s water have been depleting over the last decade due to a rapidly growing population and dwindling seasonal rains. Chennai’s population was in desperate need of a fresh water source alternative.
The Udipi 1300 MW Thermal Power Plant is a coal/gas-based power generating station located in Udipi, near Mangalore, Karnataka, India. It produces power by converting water into steam, which is then used to drive turbines. Vast amounts of the highest quality pure water are needed for the steam generation process.
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.
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.
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®).
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.
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.
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.
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.
With 37 million residents, diminishing water resources due to droughts and agricultural misuse of water, as well as a tough economy and tight budget, California is a state of constrained resources. Yet with an extended coastline and abundance of inland water resources, desalination has emerged as a solution to purify these resources and address the demand for fresh water.
