Just remember that while it will santize the water, it won't purify the water. There can still be toxins in it, even if the bacteria, viruses, etc are dead. Also be careful not to add too much salt or the water will be too salty to drink, or you'll have the problem of its return from chlorine to salt happening too quickly.
It can be an effective way of making a mild bleach solution if there's enough salt in the water and enough electricity passing through, although it's a very unstable bleach solution and will have a shelf life of probably minutes at best.

I know of one person who - many years ago - used a modified swimming pool filter and an ozone generator to turn dirty river water into potable water. Ozone is an interesting one - it kills microorganisms around 3,000 faster than chlorine. It can also take *some* impurities out of the water as it oxidises many materials.
Ozone is one of many entries on my list of things to study further...

I believe his intent was to create a weak salt solution -> create bleach solution -> pour into container with larger volume of water. Might beat a stockpile of iodine tablets in that sense, keeping in mind iodine also doesn't remove the toxins (and doesn't kill off all micro-organisms to begin with). I do agree that distillation would be the gold standard, though it may be hard to produce large quantities in a pinch. Interesting idea to play with nonetheless. |

This is an interesting one... it shows the production of chlorine gas and hydrogen gas. Why you'd need H2 in a survival situation remains a mystery to me, but there you have it anyway...  |

Peter: Hydrogen could be used as a fuel for cooking etc. Not sure I want to be making chlorine gas! This is very interesting. I don't know enough about this to rely upon it and more over there's lots of options on water supply and collection that are very straight forward. Never the less, any addition is welcome in getting the most precious resource for human survival. Found a paper on it. salekseraj.com/Page49-Badruzzaman.pdf ... I still wonder when you can just get pool shock, though the storage of it is a pain [I'm up to using glass ampules or getting the smaller sealed bags] as it absorbs moisture from the air. |

Found this one, a variation of sticking water in soft drink/water bottles in the sun.
