Saudi Arabia - Saudi Arabia's Ras Al Khair desalination plant uses RO technology and produces 1,036,000 cubic meters of seawater per day, which would make it the largest desalination plant.

As global water shortages become increasingly serious, containerized desalination has attracted much attention as an emerging seawater desalination technology. It has flexible mobility and convenient deployment characteristics, and is suitable for emergency water supply, remote areas and temporary occasions.

This article explores the advantages, challenges and prospects of application of desalination technology at home. Despite high costs, high energy consumption, and environmental impacts to consider, for coastal areas, utilizing abundant seawater resources to address water shortages is a clear choice.

The working principle of seawater desalination machine involves evaporation and condensation, reverse osmosis, multi-stage distillation, electrodialysis and water film evaporation and other technologies. These methods remove salt and impurities from seawater through physical or chemical processes, producing fresh water suitable for a variety of uses.

Desalination technology is a key means to solve the shortage of fresh water resources. Although desalination converts salt water into fresh water, not all treated water is directly drinkable and requires further treatment. This technology is widely used in fields such as water supply, industrial water supply, agricultural irrigation, and emergency rescue.
