Long term water purification

[Rush2112]

heres a very good pdf file regarding charcoal filtering. key points: if one is using activated carbon filter, no worries other than replacing the activated charcoal. filtering through regular charcoal still requires some sort of sterilization. Contrary to what many people believe, it is not necessary to boil water to make it safe to drink. Also contrary to what many people believe, it is usually not necessary to distill water to make it safe to drink. Heating water to 65º C (149º F) will kill all germs, viruses, and parasites.3 This process is called pasteurization and its use for milk is well known though milk requires slightly different time temperature combinations.

* forgot to put the time needed. keep at 65C for 30 mins. also, water must be clear. brackish water wont work.

this is just another option. u may not always be able to boil water. with pasteurization i could filter canal water thru my t-shirt into a clear bottle, put the bottle in a closed up car sitting in the sun and less than an hour i have safe water(as far as biological stuff). no heat, fuel, or smoke.

distilling water is unadvisable as it removes the micro nutrients (minerals)
as for the boiling and the 65oc etc. not all germs die at 65oc most will but not all.
milk pasteurisation is different.
milk is technically sterile the moment it comes out. same as breast milk.
I believe the 65oc of pasteurisation is only to remove pathogens that the mother could be carrying.
things like staphlococsaurus or however it is spelled will not die at 65oc neither will many others.
but that's unlikely to be in a cow.
nastys can get into water supplies.
id definitely boil risky water before drinking it, and not just heating it to 65oc for 30 mins.
also without a thermom it is difficult to know it is at 65oc for the whole time.

its easy to see if something is boiling.

Obviously I could be wrong (I often am) but I wouldn't take the risk, and I don't have a thermom, even if I did its likely to get broken.

the pathogen that causes legionaires disease is found in stagnant water. im not sure if 65oc would kill that one either, (maybe it does but im not lucky )

I believe you can revitalise distilled water by simply decanting it into another container from a height. This forces Nitrogen, Oxygen and all the other elements into the water as air bubbles are created during pouring.
Water for me is the biggest problem, as without it we have to bug out. For me the simplest and safest way to treat water is simply to boil it, it has worked for millenia

the rason brine water don't pasteurise is because saltwater all has different boiling temps, and so therefore the 65oc mark would move also.

all water has some salt content though. it is only considered brine when it gets so high
it is measured by its GH and its Kh general hardness and carbonate hardness.
I wont be carrying a test kit for gh and kh.

as tartarhorde has pointed out water that is distilled can be simply revitalised .
decanting will put some of the basic gases back which is a start and mixing it with a small amount of other water would help with some of the minerals. most water has too many anyway.

I love water chemistry , it keeps my fishies alive lol

distilled water stores very well too. mixed with a little fresh filtered water it would make that small amount of fresh filtered water go a lot further.

---

removing solids from water also affects the ph by the way.
less salts and more organics makes it acidic.
less organic and more salts makes it alkaline.
