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
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
