Beyond Reverse Osmosis: How Hybrid MED+RO Systems and Green Energy are Securing Algeria’s Water Future

By | | ,
Leave a comment

Abstract Algeria’s pure reverse osmosis (RO) desalination systems face serious vulnerabilities: increasing turbidity events and frequent membrane replacements threaten operational stability, resulting in 1,680 hours of downtime annually across active plants. As the Mediterranean warms 20% faster than the global average, water security requires urgent innovation. This article proposes a hybrid MED+RO technology (1/3 thermal + 2/3 membrane) to ensure operational resilience. If RO shuts down, MED continues independently at 33% capacity, guaranteeing minimum supply. Although hybrid systems require a 28% higher capital investment, break-even is reached in year 16 due to reduced membrane replacement costs. Optimized pre-treatment with ultrafiltration … Continue reading →

The great cultural bloom that took place during the al-Andalus period was made possible from a material and social viewpoint thanks, among other factors, to the judicious water management at those times. Countryside, cities, public bathhouses and fountains, qanats, mosques and gardens honoured the element of water. However, this water culture emerged from a distinctively Islamic conception which is briefly summarized in the following paragraphs. Water in the Holy Quran In Islam, life and knowledge originated from water, a divine gift that symbolises profound wisdom, the drink that quenches the soul’s thirst. But it is also science. Thus, the word al-ma’a – … Continue reading →

Desalination at the Heart of Algeria’s Green Hydrogen Future: Water Security as a Strategic Energy Lever

By | | , ,
Leave a comment

Algeria stands today at the crossroads of two defining transitions: the global shift toward low-carbon energy systems and the intensifying pressure on water resources across arid and semi-arid regions. In this dual transformation, green hydrogen has emerged not only as an industrial opportunity but as a strategic lever capable of reshaping the country’s energy model, export structure, and environmental trajectory. Yet, at the heart of this hydrogen ambition lies a critical enabler that is too often underestimated: desalination. Green hydrogen, produced through water electrolysis powered by renewable electricity, is increasingly recognized as a cornerstone of global decarbonization strategies [1,2].

By | | , ,
Leave a comment

Abstract The expansion of seawater desalination has significantly increased global brine production, exceeding 140 million m³/day, with more than half generated in the Middle East and North Africa (MENA) region [1]. Brine disposal poses environmental and economic challenges, particularly in semi-enclosed marine systems. Zero Liquid Discharge (ZLD) and brine valorization strategies aim to eliminate liquid effluent while recovering water and valuable minerals. This study analyzes current ZLD configurations, mineral recovery pathways, and techno-economic constraints. Particular attention is given to the Saudi Arabian national strategy as a leading example of industrial-scale brine mining. The findings indicate that hybrid membrane–thermal systems combined … Continue reading →
