Too true Stewart. £2 for a litre of water, against £17 for a filter that does 60 litres...

Jakunen, I think you'll find plastic bottles of mineral water pretty much anywhere in N. Africa now - just make sure the top is sealed before handing over the moolah. Here in Egypt we pay the equivalent of 1stg for an 18ltr bottle, or 14 pence for 1.5ltr.
When you get there, get to the nearest Pharmacy and buy a pack of INTETRIX capsules and take one every morning as a precaution (also against cholera). If you DO get the squits, take as normal - 2 every 4 hours, and spasmopyralgin at the same dose if you get stomach cramps with it.
These two together cost less than 1stg here.
Have a nice one! :wave:

Folks,

I came across this process for water purification which may be of some interest to people here.

Its called Solar Water Disinfaction or Sodis. It is being touted as a water treatment in poorer areas of the world where the climate is suitable.

The process is very simple in that it consists of filling a clean, clear 2L pop bottle with the water to be treated, shaking it vigiously for 20 seconds and then setting it in the sun for 6 hours. A combination of UV and heat treats the water. The water does need to be relatively clear for this to work and it does not remove chemical contamination.

For further info on the science behind the process see:

Anybody come across this before?

Regards,

pete

i've heard of the process of solar water purification before tho not sure how effective it really is for anything but the very smallest scale. I saw it demonstrated once in the middle east: it was like a very large (2m x 2m) very very thin fishtank about an inch wide angled towards the south west. From side on it looked very like a standard double-glazed window. This was filled with water in the early morning and left for about 12hrs all day in the sun. There was a small tap fitted at the base and this was opened as necessary in the evening to give a pretty hot but fresh-tasting water. I think that there was some very basic filtering going on, along the lines of a muslin sock over the tap but nothing more.

I doubt it'd work in blighty tho :rolmao:

Tomtom,

I will let you know next time we have some British sun! :roll:

Still, the process does seem to have some merit and might be just one of those things to file away until needed.

For instance the thread started by warning about iffy bottled water on holiday...It would seem that putting those bottles in the sun for the day may have some benifit.

Interesting how the process does not sterilize the water though; that would sugegest that once the water has been "cooked", it would be best to use it up fairly soon...

Regards,

Pete
