The nanoparticles exhibited high specific surface areas of 498.49 and 538.17 m²/g for the Co-C and Co-P samples, respectively, contributing to an impressive adsorption capacity, with Co-P achieving 100 % Cr³⁺ removal within 30 min while Co-C achieved 99.6 % Cr³⁺ removal within 40 min.

These findings suggest that the green-synthesized cobalt ferrite nanoparticles, with their high surface area and mesoporosity, hold significant potential as effective agents for environmental remediation.

ANOVA analysis further underscored the significant influence of adsorbent dosage and contact time on removal efficiency, aligning well with the freindly isotherm model.

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 % of feed water volume.

The gain output ratio (GOR) of the system is 3.07, 2.97, 2.99 and 2.98 for feed water with salinity 10,000, 20,000, 30,000 and 40,000 ppm NaCl respectively.

Egypt is advancing a major desalination initiative under a Public-Private Partnership (PPP) framework, with initial tenders expected in late 2024.

The project, managed by The Sovereign Fund of Egypt (TSFE) alongside the Ministry of Finance’s PPP Central Unit, seeks to establish renewable energy-powered desalination plants across Egypt to reach a production capacity of 8.85 million cubic meters per day (m³/day) by 2050. This aligns with Egypt’s national water security strategy and environmental sustainability objectives.

Officials from the Holding Company for Water and Wastewater presented a proposal outlining the strategic desalination plan and the targeted stations for implementation. They discussed the status of securing the necessary land for building the desalination plants as part of the plan, as well as the challenges faced during execution across different coastal governorates.

The company’s officials noted that the plan covers 11 coastal governorates, explicitly Matrouh, Alexandria, Beheira, Kafr El-Sheikh, Dakahleya, North and South Sinai, Port Said, Suez, Ismailia, and the Red Sea.
