Dear Giorgos,

I am sure you know https://en.wikipedia.org/wiki/Salt_water_chlorination and the health concern raised there. 

they are quite positive: http://www.qdmis.com/drinking-water-electrochlorination-system_p34.html

maybe their experience would be something to ask http://www.waterworld.com/articles/2015/03/europe-s-largest-potable-water-brine-electrochlorination-plant-installs-hypochlorite-generating-system.html

to what I know it is positive

 best regards

The method is commonly used. Shall I put you in contact with some suppliers?

I would investigate Cu ionization first because there are not any chlorine issues; also, it is more convenient and I would guess less expensive.  See: http://www.agri-ions.com

If foi mean use NaCl as disinfectant agent, hydrolyzing it to form NaClO, then yes, we have a very good experience. You are going to like it!' 

Chlorination of water is very common treatment process as to make water bacteriological free. In India such chemical available as bleaching power ( Calcium Oxy Chloride ). However how much chemical to be added and further process depend upon various factors. In addition to this , pre and post detailed chemical analysis is must. In particular for Residual chlorine.

Chlorine has been used for water purification for a long time, it is highly effective in combating microorganisms. However, special attention should be paid to the dosage because excess chlorine in drinking water is harmful to health.

Residual chlorine should not exceed 2 mg / l and residual free chlorine should not exceed 1 mg / l. Each specific country has its standards set, which may or may not coincide with these values.

I recommend the use of NaClO sodium hypochlorite.

regards

Our experience with NaClO sodium hypochlorite is excellence. It is cheap. Best solution is 13% product.
