Electrolysis is a process whereby electrical energy is converted into chemical energy. The difference in electrical potential between two electrodes immersed in a solution to be treated constitutes the basic principle of electrolysis. In the chemical industry, electrolysis is used to separate elements or synthesize compounds.


  • Production of hydrogen by electrolysis of water
  • Production of chlorine
  • Electrogalvanizing

Electrodialysis is a technique that consists in extracting sufficiently ionized ions from a solution. It can use less power than electrolysis, but requires a greater surface area and does not concentrate the ions to the same extent.


  • Production of drinking water from seawater
  • Demineralization of whey, deacidification of fruit juice, purification of amino acids
