Biodesalination is a concept that combines bioremediation and desalination processes to address water scarcity issues by removing salts and other contaminants from brackish or seawater. Traditional desalination methods, such as reverse osmosis, are energy-intensive and can have environmental impacts. Biodesalination aims to harness biological processes to make the desalination process more sustainable, eco-friendly, and cost-effective.

In biodesalination, biological organisms, such as certain types of bacteria, algae, or plants, are used to reduce the salinity of water. These organisms can either absorb salts directly from the water or facilitate the precipitation of salts, making it easier to separate them from the water. By leveraging the natural abilities of these organisms, biodesalination has the potential to reduce the energy requirements of desalination processes and minimize the environmental impact associated with conventional methods.
