Desalination is a process used to remove salt from seawater, but it comes with high costs and environmental impacts. Despite its advantages in providing water, challenges like brine disposal need to be addressed for sustainable water management.
Desalination is the process of removing dissolved salt and minerals from seawater or saline groundwater. It is commonly done through methods such as boiling, filtration, electrodialysis, and reverse osmosis. One of the processes, reverse osmosis, uses pressure to push water through a semipermeable membrane, trapping salts and impurities.
Countries like the United Arab Emirates, Saudi Arabia, and Israel extensively use desalinated water due to water scarcity. However, desalination has disadvantages, including high costs, energy consumption, and the production of saline wastewater that can harm the environment.
In the face of increasing water shortages globally, market forces are driving the adoption of desalination as a solution. While it helps alleviate water stress, it also poses challenges such as the disposal of concentrated brine and the high energy requirements, highlighting the need for sustainable water management practices.
