I remember reading and being taught something of a quick water cleanser: make a filter out of moss, cole, and again moss. Pour the water through. The cole is apparently supposed to be a kind of poor man's active carbon. Don't have any references to give, just something I remember hearing.

Are you looking for information on a personal survival or a community utility kind of scale?

Targan 04-24-2008, 11:46 PM This week I watched a program on ABCTV here in Australia about a desert survival course run by the Australian Army for Australian Defence Forces personnel. The participants on the course only had access to salty, brackish water for five days so they were distilling drinkable water using a metal jerry can, some hose and some heavy duty plastic sheeting/bags. It took them 8 to 12 hours to distill 5 litres of drinkable water using just one distilling rig. It was a very simple setup too.

Hangfire7 04-25-2008, 01:28 AM Filtering works, some of the items you can use to filter it are:


Lava Rock


Charcoal <please not the stuff with mesquite or easy light stuff that will poison you>


Clay


Tile <unglazed>


Several meters of clay, sand or gravel


And of course a filter strainer which can be fabric or as you guys mentioned moss or similiar.


I personal have plans and has tested one using water that has been cleaned with a few drops of bleach, then sunlight then filtered through gravel, plastic mesh, sand, mesh then charcoal and let it drip into a basin. And let it just trickle through filtering through all of the above. The sand and gravel act as a strainer, the charcoal removes alot of chemicals <remember charcoal is the active ingredient in most chemical protective suites and gas mask filters> and the bleach early on kills the living nasties.


I stuff actualy layer all of the above in a section of I think its 8 inch clay pipe that is about a meter long and just pour about two or three inches on the top and let it filter down slowly not letting more water on top to cause extra pressure, just let it filter down naturaly.



I had pondered this idea for sometime and just did it, and I am still alive so I guess it works

Boil water, turn it to steam, have something above the "pot" of boiling water to catch the steam and have it run down into your other container. Drink freash water when cool ...


(have i missed something, or is that too easy???)



2)

At night, have a bit of plastic/cling wrap streatched out but sitting above a bucket/container. Sit a small pebble on the cling wrap above the middle of the bucket/containter/ Then any condesation will hit the cling wrap and run to the low point (due to the pebble) and fall into the bucket/container.


OKaayyy, so what if there is no condesation? Put leaves from trees in the bucket (eucalypt is my favourite, or good old fashion gum tree leaves), then over night as it sweats the water condeses again on the cling wrap and drips into your bucket (with added flavour!!!).


These methods would work ok for one or two people, i couldnt see it working on a comercial scale.



(Hangfire, its been two or three days now as opposed to a few hours since you tried your method out - are you still, still alive??? :-)

Properly called a Solar Still (http://en.wikipedia.org/wiki/Solar_still). I remember seeing a docu-drama about an atlantic yachtsman who sank and spend months adrift in a liferaft before washing ashore in the Caribean islands. He had a nautical version of a solar still that floated. Plus he was smart enough to have a small bail out bag carrying extra supplies and a copy of a book from some other poor bugger who sank in mid-atlantic and spent months adrift before washing ashore

Neal5x5 04-28-2008, 09:34 AM Water that has been boiled for three minutes (at an active, rolling boil) will kill just about every organism you will encounter. The problem is if there is a chemical or radioactive contaminant. In that case, boiling may make it worse because it can aerosolize the contaminant. Likewise, water distilled from the air can contain any aerosolized contaminants, such as residual nerve gas.


Also, if the chemical contamination is severe, simply handling the water can be dangerous. Finally, the water may be physically safe to drink, but there can be residual taste and odor issues that will make it intolerable to humans.


Ironically enough, some of the biggest water contamination threats in a post-apoc world would come from water treatment facilities because of the caustic nature of the chemicals used and thier close proximity to the water source. A leak from a slowly eroding chlorine or chloramine tank into a distribution system could produce deadly results for the unwary.
