Detailed explanation-1: -Desalination is the process by which the dissolved mineral salts in water are removed. Currently, this process, applied to seawater, is one of the most used to obtain fresh water for human consumption or agricultural purposes.
Detailed explanation-2: -Desalination uses reverse osmosis technology to separate water molecules from seawater. Water from the ocean is forced through thousands of tightly-wrapped, semipermeable membranes under very high pressure. The membranes allow the smaller water molecules to pass through, leaving salt and other impurities behind.
Detailed explanation-3: -Desalination is a technique where the excess salts are removed from sea water or brackish water converting it into safe potable or usable water. Desalination methods are categorized into thermal processes and membrane processes.
Detailed explanation-4: -Desalination is a separation process used to reduce the dissolved salt content of saline water to a usable level.
