Assessment of a pilot continuous freezing desalination system with vacuum-assisted brine extraction – Egypt

The proposed pilot FD unit has multiple brine extraction stages to reach the desired water salinity.

Four distinct feed water salinity are tested. The results show that the unit has the potential to produce low-salinity water without the need for washing or crushing which causes significant mass loss. The results indicate that water is obtained at a salinity of 393 and 1225 ppm NaCl at feed water salinities equal 10,000 and 40,000 ppm NaCl, respectively.

Furthermore, the system produces an approximate constant volume equal 850 mL which is around 28 […]

Preparation of fully coated PEDOT: PSS film on MXene for high reliability capacitive deionization – China

In this paper, the sandwich PEDOT:PSS@MXene film electrode was prepared by uniformly coating PEDOT:PSS film on the surface of MXene through template-assisted polymerization. The film improves the stability of the composite by protecting the Ti layer.

The specific capacitance of PEDOT:PSS@MXene performs 185.5 F g−1 at 5 mV s−1. The desalination capacity of hybrid AC//PEDOT:PSS@MXene cell in 500 mg L−1 NaCl solution is 35.8 mg g−1.

After 40 desalting cycles, the cell performs better retention rate than AC//MXene cell (82.5 %), which keeps 97.2 %.

The morphology and structure of composite show no exists of TiO2 […]

Thermo- and light responsive microgels for efficient brackish and seawater forward osmosis desalination – Germany

In forward osmosis, microgels can be used either in a dried state or as a concentrated aqueous dispersion. A sample with 25 mol% charged units achieved a balance between water flux and responsiveness. It reached fluxes of 2.84, 4.79 and 4.39 L·m−2·h−1 for the dried state, 40 wt% and 20 wt% dispersions, respectively, when tested with 5 g·L−1 brackish water. Furthermore, a 40 wt% dispersion drew 35 g·L−1 seawater at a flux of 1.36 L·m−2·h−1.

Cyprus plans up to 10 new desalination plants to combat water scarcity – Cyprus

The government has approved a plan to build up to 10 new desalination plants to address growing water scarcity issues caused by prolonged drought and climate change, Agriculture Minister Maria Panayiotou announced yesterday.

The strategy, approved by the Council of Ministers, includes 28 actions: seven immediate, eight medium-term, and 13 long-term measures. The immediate and medium-term actions aim to address the expected water crisis in 2025-2026 and will increase water supply by more than 15 million cubic metres annually.

Four mobile desalination units have already been approved:

Desalination in Morocco to reinforce water security – Morocco

The European Bank for Reconstruction and Development (EBRD) is providing a €200 million ($211.1m) loan to phosphate-based fertiliser company OCP Group, aimed at strengthening water security through the development of new desalination facilities in Morocco.

The EBRD loan will finance the construction of two seawater desalination facilities for OCP Group, at its key industrial complexes in El Jadida (Jorf Lasfar) and Safi.

These new facilities, with a capacity of approximately 35 million m3, will support the production of fertilisers essential for global food security, enabling OCP Group to meet the increasing demand […]

Energy min inaugurates Khuzestan’s largest desalination plant – Iran

During the inauguration ceremony on Thursday, the CEO of Khuzestan Water and Sewage Company, Saber Alidadi, announced that the plant, the largest in Khuzestan, is now operational and will help improve the quality of drinking water in the province. 

Alidadi said the project is based on the B.O.O (build-own-operate) model, with a planned operational period of 15 years.

During his first visit to Khuzestan, Aliabadi also inaugurated the 400 KV Shahid Hashemi power substation located in the Shiban district.

Desalination Plant in Chile Chooses Penetron Technology for Enhanced Concrete Durability – Chile

Completed in November 2024, the expansion of the North Antofagasta Desalination Plant in Northern Chile delivers an additional 500 liters per second of drinking water by enhancing the plant’s capability to convert seawater into freshwater through advanced desalination technologies. PENETRON ADMIX, a crystalline waterproofing admixture, was specified to protect the new concrete structures from the aggressive environment of the desalination plant.

Metrowater to start replacing portion of reverse osmosis membranes in Nemmeli desalination plant by December – India

Chennai Metrowater is set to replace reverse osmosis (RO) membranes at the desalination plant in Nemmeli. The work is likely to start by the second week of December.

The desalination plant has a capacity to treat 110 million litres of seawater a day (mld). Currently, the plant produces nearly 60 mld of drinking water, which is supplied to the southern parts of the city. RO membranes are a crucial component in producing quality freshwater. The plant has 7,056 RO membranes, which are used for converting seawater into freshwater.

Dubai’s desalinated water production rises by 4.6% to meet increasing demand and keep pace with the Emirate’s growth – UAE

Dubai Electricity and Water Authority (DEWA)’s total desalinated water production in the third quarter of 2024 grew by 4.64% compared to the same period in 2023, reaching a record 40.5 billion imperial gallons. This is part of DEWA’s efforts to meet the increasing demand for water and to keep pace with Dubai’s unprecedented growth. Peak desalinated water demand reached 455 million imperial gallons per day (MIGD), which is a 4.92% increase over the same period in the previous year.
