Aquaculture Using Desalination Brine: Transforming a Waste Stream into Sustainable Food Production

By | | , ,

The rapid expansion of desalination capacity in arid and semi‑arid regions has generated an urgent need to find sustainable uses for the concentrated brine by‑product produced by seawater and brackish water desalination plants. Traditionally, brine has been treated as a waste stream, often discharged into the sea or terrestrial environments with little or no value recovery. Because most desalination technologies, especially reverse osmosis, produce brine with salinities significantly higher than natural seawater, improper disposal of this stream can lead to negative environmental impacts, including increased salinity in coastal zones, benthic ecosystem disruption, and changes in water column chemistry. However, over … Continue reading →

Advancing Circular Economy in Water Management in Algeria: From Wastewater to Strategic Resource

As climate change accelerates water scarcity across the Mediterranean and the Sahara, countries are compelled to rethink their approach to water management. The traditional linear model of extracting freshwater, using it once, and discharging it into the environment is no longer viable in regions where rainfall is decreasing, aquifers are overexploited, and agricultural demand continues to grow [1-2]. In Algeria, this challenge is especially acute – declining annual precipitation, high evapo-transpiration rates, rapid population growth, and urban expansion place tremendous pressure on limited freshwater resources. At the same time, industrial and agricultural demands continue to rise, further stressing conventional water … Continue reading →
