Yes actually I end up finding this company: http://www.cdi-electrosorption.org/ They are using this method to remove saltiness with a very low energy cost and no impact to the environment

That is good to know but actually I'm working on a product containing water meant to be drank and I'm concerned about reducing its saltiness without degrading the container (made from calcium alginate, allowing ions to go through), that's why I thought about electrolysis. I'll keep on working on it, see if indeed I can avoid the hydrolysis and still get the electrolysis to be efficient. Thank you all for your answers

Hi I wonder if we can reduce the quantity of salt (mostly Cl- and Ca2+) from water by electrolysis and still be safe to drink. I know that with inert electrods (not sure wich ones although) Cl- would be trun into Cl2(g) and I'm concerned by its toxicity even though it's going in the air. But I'm don't know what's going on about the Calcium: if it can be precipitated or if I can't get rid of it and will just need to adjust the pH. Thanks
