Taking Desalination to the Next Level, Energy Efficiency Is Key to Tapping the SeasEarth: the Blue Planet. Its nickname is derived from the fact that about 70 percent of its surface is covered by water. Yet despite its abundance, water that is readily adaptable for drinking is in short supply. In fact, about 97 percent of all water found on our home planet is saltwater that must be treated before it can be used for consumption, irrigation or industrial processes.

China Takes a Loss to Get Ahead in the Business of Fresh Water“There are large-scale desalination projects centralized all up and down the east coast of China,” ERI’s chief executive officer, Thomas S. Rooney Jr., said in an interview. “Our company has the most advanced technology in the entire desalination industry. And one of the beautiful things about China is that they like to adopt the most advanced technologies.” “You can either fight them or join them, and our philosophy is that China likely is going to be the next big desalination market,” he added. “I would rather develop technology for China in China and take a more open approach than play the secrets game.” » Go to storySeptember 13, 2011
ERI Chief Calls for Less Plant DowntimeERI chose the IDA to announce enhancements to its PX Pressure Exchanger™ (PX™) technology for seawater reverse-osmosis systems, including a 97.2% efficiency guarantee. May 22, 2011
Dispatches From Ontario: More Fresh Water With Less EnergySolutions to environmental challenges are often laden with paradoxes. Let’s take the case of desalination of sea water to make potable water. It’s becoming more common in some parts of the world, including the Mediterranean region and Australia. But there’s a catch: it’s energy-intensive, therefore carbon intensive, and for that reason it ends up contributing to the climate change cycle. » Go to storyMarch 30, 2011
Breaking ground in desalination performance and energy efficiency with high-pressure pump innovationThe high pressure pump is the heart of the desalination process—every desalination plant must have at least one high pressure pump. In plants with multiple trains, which are modular desalination units that consist of membranes, pumps, energy recovery devices, etc., each train also typically has a high pressure pump. The trains typically share common piping headers and may share common system pretreatment. » Go to storyDecember 6, 2010
Californians need water, but desalination projects are bogged downChugging a cool glass of California tap? It could be seawater flowing from that faucet. Desalination — the process of making salty water drinkable — is now producing a growing share of the national water supply as officials scramble to hydrate booming populations with dwindling fresh supply. » Go to story November 30, 2010
The Secret to Desalination: CeramicsThink of the Pressure Exchanger from Energy Recovery as an industrial Super Soaker. The company's energy-efficient desalination system revolves around applying pressure to "slugs" of water. Seawater has to be pressurized to a high level before a desalination membrane can filter out the salt and other impurities. November 2, 2010
SWRO desalination: Long-term solution for water shortagesDrought in Barcelona was forcing the government to transport water into the city. To provide a long-term solution, the Llobregat Desalination Plant was commissioned and built within two years. The success of this endeavor was marked with the award of the 2010 Global Water Intelligence Desalination Plant of the Year. October 20, 2010
SWRO Desalination: A Viable, Long-Term Solution to Water ScarcityTwenty years ago, I was engaged in a pioneering attempt to drought-proof the City of Santa Barbara, Calif., by building a series of trailer-mounted emergency desalination plants. I also have been directly involved in the design of hundreds of desalination plants operating worldwide. Since that time, the water supply/demand equation has shifted dramatically with a profound impact on municipal water rates. The evolution of technology also has increased the affordability of desalination. » Go to storySeptember 1, 2010
Desal on the RiseNew processes that complement reuse and strategies are changing the way we look at desalination. Most of the water we use comes from rivers, lakes, and aquifers, but as extraction reaches historic maximum levels, available supply diminishes to minimum levels. The dwindling water supply has tripled water rates and increased water rationing along the California coastline and in other parts of the world. » Go to story |
