Summary: Desalination of seawater is a main method for producing fresh water in many countries, but waste brine or concentrate rejects can have adverse effects on the environment due to high salinity. This study presents a simple process for reducing the salinity of concentrated brine and producing calcium and magnesium oxides, using an electrochemical system. By applying a DC potential, the system reduces the TDS of the brine solution and decreases cations and anions in the treated brine.

Summary: With the increasing global population and industrial production, the demand for water continues to rise. By 2030, 60.0% of the world population will lack access to freshwater, accounting for -2.50% of the total global water. Over 17,000 operational desalination plants have been constructed worldwide, but the main obstacle lies in the high production of brine, which is 50.0% more than freshwater and contributes to 5.0-33.0% of the total desalination cost. This paper proposes a new theoretical brine treatment approach combining electrokinetic and electrochemical mechanisms using alkaline clay. The feasibility, size, and usability of the clay have been evaluated through advanced numerical and analytical analyses, demonstrating the potential for clean brine production and mineral recovery.

Summary: Based on the evaluation of samples taken from the Brackish Water Reverse Osmosis (BWRO) plant in Eshtehard, Iran, this study demonstrated the performance of bench-scale EDR in removing total dissolved solids (TDS) from brackish water. The results showed that temperature and voltage had significant influences on the efficiency of the EDR process. The successful reduction of TDS and electrical conductivity (EC) in the second stage brine suggests that the hybrid process of RO-EDR-RO could be the best choice for the development of the Eshtehard Desalination Plant.

Summary: Seawater desalination technologies have been widely studied to address freshwater scarcity, but the disposal of desalination brine poses potential environmental risks. Alternative approaches to recover minerals, freshwater, and energy from desalination brine have been explored, with techniques including pressure-driven, thermal-driven, and electro-driven methods. Membrane/thermal integrated hybrid processes and energy recovery techniques like PRO and RED utilizing SGE have been considered for water and energy recovery, with valuable mineral products including sodium, lithium, magnesium, calcium, and other minerals being reviewed for recovery methods and product quality. Economic comparisons have been conducted to analyze the cost and revenues of each technique for operating desalination plants.

Summary: Spray evaporation is a promising desalination technology for high-salinity wastewater, but previous numerical studies neglected salt precipitation. This study experimentally investigated the evaporation of brine droplets with salt precipitation using the pendent droplet method. A reaction engineering model was developed and integrated into ANSYS Fluent for numerical simulation. The study revealed that brine droplets have different behavior compared to pure water droplets, leading to different design requirements for the spray dryer.

Summary: Forward osmosis membrane bioreactors (FOMBRs) are gaining attention for their potential to produce high effluent quality and better flux stability against fouling. This study found that a hybrid cleaning strategy involving physical and free nitrous acid (FNA) cleanings can effectively recover water flux and slow down fouling deposition during long-term FOMBR operation. The results suggest that FNA solution has the potential to not only recover membrane performance, but also to act as a strategy to mitigate fouling deposition.

Summary: Traditional discussions about energy, CO2 emissions, and human development often overlook the inequality in domestic energy and CO2 emissions. This study reveals these inequalities in India and examines the impact on both welfare and CO2 emissions as India transitions away from energy poverty. The results suggest that addressing welfare issues related to energy use, such as indoor air pollution, can be aided by a transition to modern energy carriers without a significant increase in CO2 emissions. However, the wealth creation required for a modern energy transition will lead to increased consumption, supported by carbon-intensive electricity and materials, which represents the fastest-growing source of CO2 emissions. Consequently, a coherent strategy is necessary to tackle energy poverty, wealth creation, and reduce emissions intensity in sectors like transportation.

Summary: Introducing defects into porous metal-organic frameworks is important for improving their adsorption performance. Quasi-MOFs, an underutilized variant of large-scale, fundamentally deficient MOFs, have been found to have substantial amounts of unsaturated metal sites to offset the drawbacks of MOFs. In this study, a quasi-MOF was produced using a water-stable MOF and demonstrated significantly improved phosphate adsorption capability due to the presence of defect sites.

Summary: This study focuses on the recovery of sinapic acid using liquid-liquid extraction assisted by a hollow fiber membrane contactor from an aqueous feed obtained through the hydrolysis of mustard bran. The screening of solvents of different chemical nature showed that all tested solvents had an extraction efficiency of more than 80% for pH < 5. Four solvents were selected for use in the hollow fiber membrane contactor, and the volatile solvents showed higher mass transfer coefficients compared to non-volatile solvents. The extraction efficiency was intensified by increasing the initial concentration of sinapic acid and the feed-to-solvent ratio. CPME was found to have optimal recovery efficiency at a phase ratio of 8:1, yielding 0.9 g of sinapic acid per liter of CPME used.

Summary: In this study, a nanofibrous layered structure of Ff-Ti3C2Tx-Co3O4 was prepared by self-assembling nanofibrous Co3O4 with lamellar fluorine-free MXene (Ff-Ti3C2Tx). The Ff-Ti3C2Tx-Co3O4 exhibited excellent catalytic activity for degradation, resistant to ionic interference, and maintained high removal efficiency of sulfamethoxazole (SMX) in municipal wastewater. The rapid SMX degradation involved fast electron transfer in redox cycles with PMS and the generation of 1O2 via PMS ->center dot O2 -> 1O2. This work provides new insights into antibiotic degradation mechanisms and electron transfer based on PMS activation.

Summary: In this study, sludge-derived biochar (SBC) was functionalized with various iron salts to enhance its adsorption ability for sulfamethoxazole (SMX) and magnetic collection performance. Ball milling was further employed to treat the optimal iron salt functionalized SBC (MSBC), resulting in ball milled SBC (BMSBC) with improved adsorption performance for SMX. The dominant driving mechanism for SMX adsorption onto BMSBC was confirmed to be multiple physicochemical forces, including 7C-7C conjugation, pore filling, H-bonding, Fe-O complexation, and electrostatic interactions. BMSBC exhibited favorable adsorption ability for SMX in actual waters and could be easily collected within 1 min due to its magnetic sensitivity.
