Trifluoroacetic Acid (TFA): An Emerging Threat to Water Resources and Drinking Water Safety

By | | , ,
Leave a comment

Trifluoroacetic acid (TFA) has emerged as one of the most widespread and persistent fluorinated contaminants detected in the environment. As an ultra-short-chain member of the per- and polyfluoroalkyl substances (PFAS) family, TFA exhibits exceptional water solubility, high mobility, and extreme environmental persistence. Unlike legacy PFAS such as perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS), TFA is primarily generated through the degradation of fluorinated refrigerants, pesticides, pharmaceuticals, and industrial chemicals. Recent monitoring studies have revealed its increasing occurrence in rainwater, groundwater, surface waters, drinking water, food products, and even human serum. This review aims to summarize current knowledge regarding TFA sources, … Continue reading →

The Role of Dissolved Gases and Ionic Composition in Reverse Osmosis Desalination

By | | ,
Leave a comment

As global water stress intensifies, seawater desalination has become one of the cornerstones of water security in arid and semi-arid regions. From the Gulf countries to the Mediterranean basin, Australia, and parts of North America, desalination plants now produce tens of millions of cubic meters of drinking water every day. Reverse osmosis (RO) has emerged as the dominant desalination technology due to its increasingly competitive energy efficiency and the continuous improvement of membrane performance [1]. However, beyond traditional operational parameters such as salinity, pressure, and recovery rate, one critical factor often remains underestimated: seawater temperature. Its influence extends far beyond … Continue reading →

The Vanishing Aquifers in MENA: An Overview

Aquifers are of tremendous importance for the MENA as world’s most water-stressed countries are located in the region, including Kuwait, Qatar, UAE, Palestine, Saudi Arabia, Oman, Iran, Lebanon and Yemen. However, aquifers in MENA are coming under increasing strain and are in real danger of extinction. Eight aquifers systems, including those in MENA, are categorized as ‘over stressed’ aquifers with hardly any natural recharge to offset the water consumed.   Aquifers in MENA Aquifers stretched beneath Saudi Arabia and Yemen ranks first among ‘overstressed’ aquifers followed by Indus Basin of northwestern India-Pakistan and then by Murzuk-Djado Basin in North Africa. The Nubian Sandstone Aquifer … Continue reading →

Desalination at a Turning Point: Breakthrough Innovations Driving Sustainable Water Production

By | | ,
Leave a comment

Desalination has become one of the most important technological pillars for addressing global water scarcity. As climate change intensifies droughts, population growth increases water demand, and industrial development places additional pressure on freshwater resources, desalination is evolving from an alternative water source into a strategic component of water security [1,2]. Recent advances presented at international scientific forums reveal that the sector is undergoing a profound transformation. No longer focused solely on producing freshwater from seawater, modern desalination is increasingly characterized by resource recovery, energy efficiency, environmental sustainability, digitalization, and integration with renewable energy systems. One of the most significant breakthroughs … Continue reading →

Water-Food Linkage in the Arab World

By | | , , ,
1 Comment

The water-food linkage represents an important and vital nexus in the Arab countries. Under the current unstable food security situation (fluctuating energy prices, poor harvests, rising demand from a growing population, the use of biofuels and export bans have all increased prices), the ability for the Arab countries to feed their growing population is severely challenged by competition over increasingly limited water resources. Agriculture is currently challenged by competition among sectors on available water resources. While the majority of water in the Arab region is used inefficiently in the agricultural sector (about 85% with less than 40% efficiency), which is … Continue reading →

Valorization of Desalination Brines into Molten Salts, Carbonates and Thermal Fluids

By | | , , ,
Leave a comment

The management of brines generated from seawater desalination has become a central issue in arid and semi-arid regions, particularly in Mediterranean basin countries and the Middle East. The rapid increase in desalination capacity, especially through reverse osmosis, has helped secure access to drinking water but has also generated a growing stream of hypersaline discharges. Global estimates indicate that worldwide brine production now exceeds 140 million m³/day, or more than 50 billion m³/year, with continuous growth driven by industrial desalination development [1]. One of the most widely studied pathways is the transformation of salts contained in brine into materials for thermal … Continue reading →

PFAS in Water Systems: Sources, Challenges and Emerging Removal Technologies

Abstract Per- and polyfluoroalkyl substances (PFAS) have emerged as one of the most critical classes of persistent organic contaminants threatening global water resources. Due to their exceptional chemical stability, resistance to degradation, and widespread industrial applications, PFAS are increasingly detected in groundwater, surface water, wastewater, and even drinking water supplies. This article reviews the origin and environmental pathways of PFAS contamination, with a particular focus on aquatic systems. It also examines the principal analytical techniques currently used for PFAS detection and quantification in water matrices, including LC-MS/MS and high-resolution mass spectrometry. Furthermore, the study critically analyzes conventional and advanced PFAS … Continue reading →

Rethinking Desalination through Digital Twins: From Energy-Intensive Processes to Intelligent Water Systems

By | | , ,
Leave a comment

The increasing global water scarcity driven by climate change, population growth, and industrial expansion has positioned desalination, particularly seawater reverse osmosis (SWRO), as a strategic solution for ensuring water security. However, desalination processes remain energy-intensive, operationally complex, and sensitive to variations in feedwater quality and membrane performance. In this context, the emergence of the Digital Twin represents a paradigm shift in the management and optimization of desalination systems. What is Digital Twin? A digital twin is generally defined as a dynamic virtual replica of a physical system that integrates real-time data, physics-based models, and advanced analytics to simulate, predict, and … Continue reading →

Water-Food-Energy-Ecosystems Nexus in MENA: Role of Startups and Entrepreneurship

By | | , , ,
Leave a comment

The MENA region stands at the intersection of some of the most acute resource challenges globally. Water scarcity, energy dependency, food insecurity, and ecosystem degradation are not isolated crises; they are deeply interconnected, reinforcing one another in complex and often unpredictable ways. The Water–Energy–Food–Ecosystems (WEFE) Nexus has emerged as a conceptual and operational framework to address these interdependencies, promoting integrated resource management and cross-sectoral coordination. Yet, despite its conceptual maturity and policy recognition, the WEFE Nexus in MENA remains largely under-implemented. The missing link is not knowledge, nor policy ambition, it is execution. Increasingly, startups and entrepreneurship are emerging as … Continue reading →

Decentralized Brackish Water Desalination as a Catalyst for Climate-Resilient and Sustainable Agriculture

By | | , ,
Leave a comment

Water scarcity has emerged as one of the most pressing challenges facing the Mediterranean basin, a region characterized by sharp climatic gradients, demographic pressures, and structural inequalities in resource distribution. Agriculture alone accounts for between 64% and 79% of freshwater withdrawals in many Mediterranean countries, particularly in the southern and eastern shores, where irrigation is essential for food security and rural livelihoods [1]. Climate change is intensifying these pressures through increased frequency of droughts, rising temperatures, and declining precipitation, thereby exacerbating groundwater depletion and salinization [2]. In this context, decentralized brackish water desalination is gaining recognition as a promising pathway … Continue reading →
