This may have been covered before, but....

How do you construct a filter for water out of natural materials?

I have seen an image of a filter made with three scarves, and I have heard tell of a permanent filter to be made of strata of natural materials.

How does this work?

Any specifics?

Having no practical experience with this, I have a Swedish army survival manual pdf. file with instructions for something similar. Although the filters uses either a can (beercan?) or a bucket, the internal components are charcoal, a type of moss which latin name is Sphagnum sp., tiny rocks, and peat.

The peat should be brown in colour, and must not have decayed too much. If you squeeze the peat, the water that comes out should have a clear but slightly yellow colour. Such peat can be found from a couple of tens of centimeters down to 50 centimeters in the ground. For each liter of peat, you need a 1/2 liter of finely ground charcoal. Mix the peat and the charcoal togheter.

Now, for the beercan, cut the top open and poke a lot of holes in the bottom. Then put a layer of moss in the bottom, and cover it with the peat and charcoal mix. Lastly put some rocks on top, and your water filtering can start. Pour the water in at the top.

The manual states the the filter should clean 100- 200 times it`s own volume. Wheter this filter really works or not, I can`t say for sure since I haven`t tested it.

The pdf. used to be available online, I`ll see if I can find the url. The manual is in Swedish, but it has lots of pictures. Anyway I have the pdf., so if someone really wants that manual, I suppose I can send an e- mail.
