We are seeking information fro a project in Nepal. At the Living River Health Serves, they are interested in using potassium permanganate to make dirty river water potable. It has been suggested that a 1:500,000 dilution is needed, but this makes the water quite purple. Is this the right dilution or can it be used at 1:1,000,000. How long does it take before it is drinkable ? Does this kill cysts like giardia ? What else needs to be done if the water is turbid?Any information would be helpful. Please send any comments to the list in general or to me: mailto:benedict_tisa@jsi.com
Thanks in advance for every ones help
Cheers,
