Tender for new Paphos (Cyprus) desalination plant in summer

A tender competition is to be announced in the summer for the construction of a new desalination plant in Paphos, acting head of the Water Development Department (WDD) Andreas Manoli said on Thursday.

The Cabinet gave the go-ahead on Wednesday for the construction of a desalination unit with a daily capacity of 15,000 cubic metres. The unit is to be built in Kouklia, in the same location where a mobile desalination unit had been installed in 2010, which is now being dismantled.

According to the cabinet, the decision was taken as part of the government policy to secure alternative access to […]

Membrantechnik im Wasserwerk – Erfahrungen mit der Entfernung von störenden Inhaltstoffen

In Zusammenarbeit mit der Universität Duisburg/Essen, der Deutschen Gesellschaft für Membrantechnik (DGMT) bietet DME GmbH im Juni 2017 das Seminar:

„Membrantechnik im Wasserwerk – Erfahrungen mit der Entfernung von störenden Inhaltstoffen“ (Fr. 23.06.2017)

in deutscher Sprache an.

Im Rahmen ausgewählter Vorträge geben Experten Einblick in den Stand der Technik, Forschungsaktivitäten, betriebene Membrananlagen, Umsetzungsmöglichkeiten der Technologien und regulatorische und rechtliche Rahmenbedingungen.

Neben dem gezielten Blick auf die Entferenung von störenden Inhaltsstoffen wird auch der Umgang mit gerade diesen dann entstehenden Konzentraten technisch und rechtlich betratet werden.

Vortragen werden:

– Bezirksregierung Düsseldorf, Jörg Matthes*
– IWW Mühlheim, Wolf Merkel*
– Universität Duisburg-Essen, Stefan Panglisch
– LANXESS, Alexader Schefler*
– Stadtwerke Dinslaken, angefragt
– […]

Trinkwasser aus der Wüstenluft – Metallorganischer Werkstoff mit extrem großer innerer Ober­fläche ent­wickelt.

….

Extrem poröse Verbindungen aus Metalloxiden und organischen Salzen verfügen über bis zu 7000 Quadrat­metern Ober­fläche pro Gramm. Die künst­lich hergestellten metall­organischen Gerüste – kurz MOF vom englischen metall-organic framework – gelten daher als vielversprechende Materialien für die Trennung von Gasen, sowie für Batterieelektroden oder Katalysatoren. Eine Forschergruppe um Omar Yaghi vom Lawrence Berkeley National Laboratory entwarf jetzt ein MOF-Material zur Gewinnung von Trinkwasser. Selbst bei einer geringen Luftfeuchte von zwanzig Prozent, die beispielsweise in der Sahara herrscht, war ein Prototyp effizient genug, um einige Liter Wasser in einer Nacht sammeln zu können.

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 […]
