Savior or Albatross? Proposed desalination plant could decrease South Bay’s dependence on imported water, but has raised environmental concerns


.

And neither is the debate over desalination. The West Basin Municipal Water District, the water supplier for the broader South Bay area, has proposed building an ocean water desalination plant near the NRG power generation campus off Vista del Mar. Two possible plants — one producing 60-million gallons-per-day, the other 20 million — are under consideration. An environmental impact report has been in the works since August 2015, and is set to be released sometime this year.

Spurred by concerns from local environmentalists, the Beach Cities have formed an opposition block to the project. Hermosa Beach and Manhattan [

A joint venture between a division of Italy’s Salini Impregilo and Spain’s Abengoa has signed a $225m agreement with ACWA Power for the development of a desalination plant in Shuaiba, Saudi Arabia.




The Salini unit, Fisia Italimpianti, and Abenoga will design and build the plant for ACWA Power on behalf of the Saline Water Conversion Corporation, the Saudi state-owned water utility company.

Located in the Shuaiba area on the western coast of Saudi Arabia, the plant will use reverse osmosis technology to deliver up to 250,000m3 of water per day, and supply potable water to more than one million residents in the cities of Mecca, Jeddah and Taif.

The joint venture has signed a ‘limited notice to proceed’ agreement for the preparatory work, and expects to sign the ‘full notice [

Carbon nanostructures supplied by Lockheed Martin are special; they are networked


.

The group has leveraged the electrically conductive nature of a special kind of nanofiber, called carbon nanotubes (CNT). CNTs are tiny cylindrical tubes made of tightly bonded carbon atoms, measuring just one atom thick. But the CNTs Dr. Hashaikeh’s team used, which were provided by global security, aerospace, and information technology company Lockheed Martin, are not ordinary CNTs.

“The carbon nanostructures supplied by Lockheed Martin are special; they are networked. This means that they are composed of many interconnecting channels that branch off in all directions. This interconnectivity is what enables the entire membrane to become completely cleaned [

Water harvesting from air with metal-organic frameworks powered by natural sunlight

Abstract:
Atmospheric water is a resource equivalent to ~10% of all fresh water in lakes on Earth. However, an efficient process for capturing and delivering water from air, especially at low humidity levels (down to 20%), has not been developed. We report the design and demonstration of a device based on porous metal-organic framework-801 [Zr6O4(OH)4(fumarate)6] that captures water from the atmosphere at ambient conditions using low-grade heat from natural sunlight below one sun (1 kW per square meter). This device is capable of harvesting 2.8 liters of water per kilogram of MOF daily at relative humidity levels as low [

Desalination plant will not see light of day in Mumbai – India

Such desalination projects are operational in cities like Dubai and Chennai. The desalination proposal was meant to tide over poor rains in the catchment of the dams which supply water to Mumbai. The BMC’s ambitious plans for a Rs 1,000 crore desalination plant to quench Mumbai’s increasing thirst for water seem to have formally come a cropper. While the demand for water in Mumbai is 4,250 MLD, the supply from six water sources hovers at a much lower quantity of 3,400 MLD. While desalinated water would cost citizens Rs 70 per 1,000 litres, the BMC supplies 1,000 litres of [

New desalination plant operated by Unicef – (Israel Defence Forces (IDF) tells UN Gaza faces an ‘impending humanitarian crisis’)

A top commander in the Israeli army has written to the United Nations to warn that the Gaza Strip is on the brink of a water and electricity crisis.

Major General Yoav Mordechai, the Israel Defence Forces (IDF) coordinator of government activities in the Palestinian Territories, sent letters to several international bodies including the UN’s special envoy for the Middle East peace process, to say that urgent action is needed to prevent the situation for civilians from deteriorating (LINK).

DĂŒrre auf Kuba: Regierung setzt auf Meerwasserentsalzung



.

Die Insel verfĂŒgt ĂŒber eine hydraulische Infrastruktur von 242 DĂ€mmen, Dutzende von Mikro-DĂ€mmen, etwa 2.420 AquĂ€dukte (Netzwerk von ĂŒber 22.000 Kilometer Wasserleitungen/Rohre), fast 70 Wasseraufbereitungsanlagen und zahlreiche Pumpstationen. Die seit Jahren herrschende DĂŒrre verursacht einen Mangel der Wasserressourcen, die 242 DĂ€mme weisen aktuell ein kumuliertes Gesamtvolumen von nur noch 38 Prozent auf.

Meerwasserentsalzung ist die Gewinnung von Trinkwasser und Betriebswasser fĂŒr Industrie- oder Kraftwerksanlagen aus Meerwasser durch die Verringerung des Salzgehaltes. Die Entsalzung kann auf verschiedenen Prozessen beruhen, die Salze und Mineralien aus dem Wasser entfernen. (LINK)

Cuba’s struggle for water

Cubans face a daily battle for drinking water as the country experiences one of its worst droughts in 100 years.

Cuba is experiencing one of its worst droughts in 100 years. Although the government provides drinking water, the shortages caused by the lack of rain are compounded by an aging and dilapidated infrastructure. More than 50 percent of the available water is lost to a leaking drainage system and state water officials must manually change the flow of water in the pipes every day to ensure an equal water divide between houses and neighbourhoods.

Even so, some cities in [

Chennai/India – Desalination plant has good governance

BJP poll promises: Desalination plant, good governance

The saffron party also assured to take steps for a desalination plant in the constituency if its candidate Gangai Amaran was elected.

The BJP on Sunday appealed to the RK Nagar voters to give a chance to the party to ensure Prime Minister Narendra Modi’s good schemes and corruption free governance, to Tamil Nadu. The saffron party also assured to take steps for a desalination plant in the constituency if its candidate Gangai Amaran was elected. (LINK)
