Chemicals sent to Tobruk seawater desalination plant – Libya – Tobruk

The operators of the Zliten Desalination Plant have shipped several barrels of chemicals to Tobruk seawater desalination plant after it ceased operation due to running out of these substances. An official at the Tobruk station said the eight desalination plants in Libya along the Libyan coast from Tobruk to Zuwara need chemicals constantly and all declared a state of emergency for the severe shortage of chemical supplies.

„It is illegal to sell water“ Water and Sanitation Department spokesman Sputnik Ratau said – South Africa – Cape Town

….

Meantime, with water rationing underway, and dire warnings of “day zero” when supply will run completely dry, enterprising profiteers are taking advantage of the shortage. Water restrictions, threats of prosecution and a sense of panic have some residents willing to pay for alternative water supplies for gardening, swimming pools and flushing toilets.

Water and Sanitation Department spokesman Sputnik Ratau said the government was the custodian or trustee of water resources, including dams, rivers, lakes, pans, wetlands and groundwater. „It is illegal to sell water. The only case in which water is sold legally is as bottled water,“ he […]

Shutdown of the Point Lisas Desalination Plant – Trinidad – Point Lisas

Citizens are advised that water schedules throughout Trinidad may be affected by the planned shutdown of the Point Lisas Desalination Plant from Monday October 30 to Sunday November 5, 2017. In a release, the Water and Sewerage Authority (WASA) said it was advised by the Desalination Company of Trinidad and Tobago (Desalcott) of the rescheduled planned shutdown of its Desalination Plant at Point Lisas to facilitate maintenance works. The planned shutdown will now take place from Monday 30th October to Sunday 5th November 2017 and will have a significant impact on WASA’s overall supply position in Trinidad. The Desalcott […]

Asahi Kasei’s Microza™ Hollow-Fiber Membrane Selected for Desalination Plant in Kuwait Japan – Tokyo

Microza™ hollow-fiber membrane for water treatment from Asahi Kasei was selected as pretreatment membrane for the Doha Phase 1 reverse osmosis (RO)1 seawater desalination plant to be built near Kuwait City by Doosan Heavy Industries and Construction, a major Korean plant construction company. The Asahi Kasei membrane treatment capacity for this project is scheduled to be 610,000 tons per day, representing the largest hollow-fiber filtration membrane order received by Asahi Kasei. Many RO plants for seawater desalination are planned in Kuwait and other countries of the Middle East to address chronic shortages of fresh water, with microfiltration (MF) and […]

Cape Town will have its first desalination plants working just weeks before the city’s dams are expected to go dry South Africa – Cape Town

That’s according to Xanthea Limberg, the City of Cape Town mayoral committee member for informal settlements, water and waste services, and energy . „Monwabisi and Strandfontein [plants] are currently scheduled [to start operating in] February but we are exploring opportunities to implement earlier, once internal funding issues are resolved,“ Limberg told The Times. Mayor Patricia de Lille said earlier this month that the municipal water supply might dry up in March if usage was not reduced. Chris Braybrooke, general manager of water technology company Veolia, said completion of tendering for the desalination plants should have been six months ago […]

Az Zour North facility is Kuwait’s first independent desalination plant and power station, accounting for up to 20% of the country’s desalination capacity and up to 10% of its energy capacity – Kuwait

A quick aerial view of the state of Kuwait brings one of the country’s most pressing challenges into sharp focus – meeting the water needs of a growing population in a landscape dominated by desert sands. In a recent study, the World Resources Institute ranked Kuwait among the top ten countries globally that are likely to face extremely high water stress by 2040. With average annual precipitation of just 121mm per year and no permanent rivers or lakes, it is no surprise that more than 90% of water for domestic and industrial needs and up to 60% of total […]

MIT suggests a different approach to reducing the rate of fouling – USA

…

The prevailing idea in the industry has been that the high pressure required by RO is responsible for the relatively high rate of fouling, compared to other systems such as forward osmosis. But the MIT study shows that this is not the case, a finding that opens up new approaches to reducing fouling in RO. The research, by Emily Tow ’12, SM ’14, PhD ’17 and MIT Professor John H. Lienhard V, was recently published in the Journal of Membrane Science and presented at the 2017 AMTA/AWWA Membrane Technology Conference, where it received the Student Best Paper Award.

Desalitech’s Closed Circuit Reverse Osmosis (CCRO) Germany – Köln

Lanxess adds CCRO module to its LewaPlus design software

Lanxess has added reverse osmosis (RO) and ion exchange (IX) system dimensioning capabilities to its LewaPlus software suite. The module provides system modeling with Desalitech’s Closed Circuit Reverse Osmosis (CCRO) technology and enables the dimensioning of RO systems, helping system designers bring their water treatment footprint closer to zero liquid discharge (ZLD) or minimum liquid discharge (MLD) goals. Reverse osmosis is used for the desalination and purification of water and is widely used, especially in areas of water stress such as the American West. The traditional reverse osmosis process is […]

Nickel Hexacyanoferrate Electrodes for Continuous Cation Intercalation Desalination of Brackish Water – USA – Illinois

Abstract:

Using porous electrodes containing redox-active nickel hexacyanoferrate (NiHCF) nanoparticles, we construct and test a device for electrochemical water desalination in a two flow-channel device where the electrodes are in direct contact with an anion-exchange membrane. Upon reduction of NiHCF, cations intercalate into it and the water in its vicinity is desalinated; at the same time water in the opposing electrode becomes more saline upon oxidation of NiHCF in that electrode. In a cyclic process of charge and discharge, fresh water is continuously produced, alternating between the two channels in sync with the direction of applied current. Compared to […]
