Optimize and analyze a large-scale grid-tied solar PV-powered SWRO system for sustainable water-energy nexus Desalination (IF 9.9) Pub Date : 2024-02-20 Mohamed R. Elkadeem, Kotb M. Kotb, Swellam W. Sharshir, Mohamed A. Hamada, Abd Elnaby Kabeel, Ibrahim K. Gabr, Mohamed A. Hassan, Muhammed Y. Worku, Mohammad A. Abido, Zia Ullah, Hany M. Hasanien, Fathalla F. Selim
The lack of clean water and access to energy are two major obstacles to global sustainable systems. The development of solar photovoltaic (PV) technology gained the attention of water desalination projects due to its cost decline, carbon-free emission, and the on-site energy production. However, studies on in-depth analysis of the performance of these systems remain rare. This study performs a comprehensive

Growth of TiO2/Ti-MOF nanorod array with enhanced photoabsorption and photocatalytic properties on carbon cloth for efficient auto-cleaning solar desalination Desalination (IF 9.9) Pub Date : 2024-02-20 Ruru Meng, Yang Lu, Liming Zou, Hongde Du, Xiaolong Li, Bo Zhu, Daniel K. Macharia, Majid Amidpour, Zhigang Chen, Lisha Zhang
Solar-enabled seawater desalination has attracted increasing attention for mitigating the freshwater crisis worldwide, while the practical applications are vitally restricted due to unsatisfactory photoabsorption and membrane contaminations from organic-matter adsorption and sea-salt deposition. To settle the above issues, herein we report the growth of TiO/NH-MIL-125(Ti) nanorod array with enhanced

Effect of sodium chloride on yield, purity, morphology and polymorphs of calcium or magnesium carbonate sequentially precipitated from brine solution Desalination (IF 9.9) Pub Date : 2024-02-19 Naswibu A. Kasimu, Jun Gu
Oilfield brine disposal in marine environments is undesirable due to concentrated salts of calcium, magnesium, sodium, and others which endanger aquatic organisms. Thus, it is paramount essential to precipitate the dissolved ions into stable carbonates for industrial applications. However, the effect of NaCl in the brine solution on the quantity and quality of precipitated carbonates is not yet reported

New model of nutrient utilization and salt regulation of anaerobic digestate from food waste Desalination (IF 9.9) Pub Date : 2024-02-19 Yongze Li, Chujie Qi, Yazhou Tang, Bo Liu, Bo Bian, Li Gao, Linhua Fan, Zhenzhen Zhao
Anaerobic digestion (AD) treatment of food waste (FW) has become increasingly popular, in the meantime, it creates a challenge for effective management of its by-products. The study of biogas slurry (BS) treatment methods is an ongoing endeavor. In this study, we formulated the following scenarios for the treatment of BS: S1 as sewage treatment, S2 as a base rice fertilizer, and S3 as an additional

Engineering PVDF omniphobic membranes with flower-like micro-nano structures for robust membrane distillation Desalination (IF 9.9) Pub Date : 2024-02-17 Jie Xu, Kecheng Guan, Ping Luo, Shanshan He, Hideto Matsuyama, Zhaoxiang Zhong, Dong Zou
Conventional PVDF membranes are easily wetted and contaminated in membrane distillation (MD) process, especially when used in separating high-salinity water and oil-contained saline water. To address these issues, an omniphobic membrane was fabricated in this work. ZnO micro-flowers with a rough structure were successfully deposited onto the PVDF membrane with the assistance of polydopamine assistance

Nanofiltration membranes for sustainable removal of heavy metal ions from polluted water: A review and future perspective Desalination (IF 9.9) Pub Date : 2024-02-17 Mwema Wanjiya, Jia-Chen Zhang, Bin Wu, Ming-Jie Yin, Quan-Fu An
The increase demand on clean water accompanied with water shortage is now threatening the ecosystem and human life, which is aggravated with the rising of heavy-metal-ion polluted water. Thus, water purification from metal-ion contained wastewater is of significance. The metal ions removal could achieve two aims simultaneously: harvesting clean water and recovering the valuable metal resource. Nanofiltration

Novel data-driven optimal control methods for cost-effective brine treatment Desalination (IF 9.9) Pub Date : 2024-02-16 Mustafa F. Kaddoura, Natasha C. Wright
This study presents a novel data-driven optimal control method to minimize the cost of Convection-Enhanced Evaporation (CEE) systems under time-varying weather conditions. CEE is the approach of evaporating water from saline films (brine) on packed evaporation surfaces by air convection. Here, operating variables (brine injection rate, brine temperature, and air speed) are actively controlled as a
