Miles and miles of gorgeous Red Sea coastline draw tourists to Egypt every year. And while most of Egypt’s residents have access to fresh water from the River Nile, transporting it to the farthest reaches of the Egyptian coast is expensive. Tourism is a significant part of Egypt’s economy, and coastal towns are looking to seawater reverse osmosis (SWRO) desalination as an option for bringing fresh water to tourist destinations.
As electricity production increases in China to keep pace with the nation’s rapid economic growth, power providers are caught in a bind: energy generation requires processed water, but desalinating seawater to feed power plants requires significant energy. The 4,000 MW power stations expanding China’s electrical grid in preparation for the 2008 Olympics required a seawater reverse osmosis (SWRO) plant capable of processing significant quantities of water and a careful balance of energy considerations.
Limited water resources were holding back social and economic development in Tianjin Dagang, the largest industrial city in Northern China. An early adopter of desalination to meet municipal and industrial water needs, Tianjin sought to develop a massive desalination plant to enable a large, new industrial development.
Shengsi, an island in Zhoushan, China’s largest archipelago, is known for its beaches, fishing, and salt production. The area has more than 79,000 residents and hosted more than 2.7 million tourists in 2012, a number that strains the island’s minimal natural water supply. Before constructing a desalination plant, daily water flow and availability could be severely limited especially during drought season.
In the vibrant seacoast city of Qingdao, China, a diverse population of over 8 million people shares space and resources with rapidly growing industry. The pressing need for a larger municipal water supply led government leaders to commission a seawater reverse osmosis (SWRO) water treatment plant.
The quality and availability of freshwater supplies in Turkey are unpredictable. This is because rainfall variations, geographical irregularities, urbanization, industrialization, and agricultural modernization all complicate water use for human, industrial, and agricultural purposes. Turkey has no natural oil or gas resources and must make deliberate and thoughtful decisions about its energy acquisition and use.
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.
