Summary: The impacts of climate change and population growth lead to a greater demand for food and new water resources. Seawater, which makes up 93% of Earth's surface, is being explored as a sustainable water source. This article reviews and compares various biological tools for water desalination and their efficiency compared to industrial systems. Bacteria in microbial desalination cells can generate the required energy for desalination, with salt removal efficiency ranging from 0.8 to 30 g/L/d. Algal cells can grow in high salt concentrations and be used for seawater desalination without prior treatment, achieving salt removal efficiency of 0.4-5 g/L/d. Biopolymers enhance water evaporation and are used in solar steam generators for seawater treatment. Despite progress, further improvements are needed for sustainable and cost-effective biological water desalination.
