France does not depend on desalination process for getting fresh water.
Desalination is a process that removes minerals from saline water. More generally, desalination refers to the removal of salts and minerals from a target substance, as in soil desalination, which is an issue for agriculture.
Due to its energy consumption, desalinating sea water is generally more costly than fresh water from rivers or groundwater, water recycling and water conservation.
Desalination is particularly relevant in dry countries such as Australia, which traditionally have relied on collecting rainfall behind dams for water.
Water pollution can be controlled in the multiple ways. It is best controlled by the dilution of water. The pollutants must be treated chemically and must be converted into the non toxic substances. The low level of radioactive wastes in the water is removed by the oxidation of ponds. There are certain chemicals which act on the organic insecticide and are used in the pesticide. There are different techniques which are very helpful in the process of thermal pollution and involve the cooling, evaporation, water cooling; cooling can be wet or dry.
