Melbourne’s dwindling water storages could trigger maximum order from desal plant (Australia)

Victoria’s near-record dry winter has pushed Melbourne’s water storages close to the level where the state will start to prepare for drought, which could involve cranking up the multibillion-dollar desalination plant to its full capacity for the first time.

A new threshold set by the Andrews government requires the state’s water corporations to begin to prepare for drought should Melbourne’s water storages drop below 60 per cent by November 30. The previous threshold was 54.1 per cent.

Melbourne’s dams are 62 per cent full and dropping towards the new mark following the state’s driest June since records began in 1900. […]

OPWP seeks ministry’s approval for water desalination project in Salalah (Oman)

Oman Power and Water Procurement Company (OPWP) plans to build a 22 million imperial gallons per day (100,000 cubic meters per day)-capacity seawater desalination project in Dhofar to meet growing demand for potable water.

The proposed project, which will be given to a private developer on a Build, Own, Operate (BOO) basis, is awaiting approval from the country’s Ministry of Finance (MoF).

OPWP, which oversees procurement of all new water and electricity capacity in the Sultanate, has already started an initiative to find a suitable site for the project, according to the seven-year outlook report released by the company.

Private desalination plant told to suspend operations (India)

Administration says it had failed to set right infrastructure.
The district administration has asked the South Ganga Water Technology Private Limited, a private desalination plant, at the coastal Krishnapuram, near here to temporarily suspend operations for failing to set right the infrastructure in the plant as per the guidelines.

As the officials failed to renovate and set right the infrastructure as per the stipulated guidelines in the given time and the re-inspection by the Joint Committee revealed that the plant was functioning without the promised modifications, it was asked to suspend operations, an official release said on Friday.

Pumpen zur Meerwasserentsalzung

…

Hier stehen Verfahren zur Verfügung – insbesondere die Umkehrosmose –, die als kontinuierliches Verfahren in großindustriellem Maßstab nutzbar sind. Zu den Kernkomponenten derartiger Anlagen gehören Hochdruckpumpen. Ihre Aufgabe ist es, die Membranen der Osmoseanlagen mit hoch korrosivem Salzwasser zu beschicken. Die Trägerflüssigkeit passiert die Membran, während die Feststoffanteile zurückgehalten und abgeschieden werden.
Als Hersteller von Hochdruckpumpen für anspruchsvolle Aufgaben und korrosive beziehungsweise abrasive Medien hat sich…

Characterisation and comparison of bacterial communities on reverse osmosis membranes of a full-scale desalination plant by bacterial 16S rRNA gene metabarcoding

PERTH, Australia – A benchmarking study has been carried out on the bacterial build up on reverse osmosis membranes at a full-scale desalination plant which could help prevent biofouling in future operations.

Murdoch University PhD student Veena Nagaraj examined the bacteria living on the membranes on 14 reverse osmosis units in the Perth seawater desalination plant in Rockingham after seven years of operation.

She then compared them to the unused units waiting in the plant for installation.

Before reaching the reverse osmosis membranes, the water has already gone through sand filtration, micro-filtration and chemical treatment to try to remove […]

mayor of Brockton pursues a plan to buy the Aquaria desalination plant for $78 million, other elected officials representing the city are exploring another way to meet the community’s supplementary water needs

…

“It’s just a better business decision,” Carpenter said. “It’s now or never on Aquaria. … What we’re proposing is 0 percent uncertainty, and 100 percent equity.”

Farwell, however, said there is some uncertainty with the Aquaria option as well. He pointed to electricity costs as an example, referring to an analysis completed last year by the city-contracted firm CDM Smith. Although Brockton would be immune from three years from electricity rate increases, after that an increase of just $0.01 in the electricity rate would spike the operating costs of the Aquaria plant by $50,000, the CDM Smith report […]

Motion of the Ocean Generates Fresh Water (RO)

Sandia Labs’ findings have helped Atmocean attract about $3.5 million in investment to continue product testing, add staff and boost component manufacturing at Reytek. The company built full-size seawater pumps and tested the system off the coast of Oregon in 2011 and off Peru for six months in 2015. “The first Peru tests were a big success,” Kithil said. “Other small communities want to see if it will work for them.”

Atmocean is working now with Sandia Labs engineer Tim Koehler on computational modeling of the wave energy system. Following trials in a test tank at the Texas A&M […]

In California the drought is over, so now what is the plan for local water agencies?

…

As the worst drought in California’s recorded history fades from memory, and mandatory water conservation cutbacks become a thing of the past, California water agencies are left to grapple with the question: What do they do now?

About 80 representatives of Inland Empire water agencies gathered at a symposium at the Chino Basin Water Conservation District (Chino Basin) headquarters in Montclair on June 29 to discuss that and many other topics, ranging from climate change to wastewater recycling to desalination. Not least among the topics was rates, and how to pay for new technologies to ensure a safe, […]
