[pct-l] SODIS - Solar Water Disinfection

[Jim & Jane Moody]

I have no direct experience with this method, but I imagine the treatment times would be dependent on raw water temperature and turbidity (clarity).  I know that chlorine dioxide tabs (e.g., Micropur from Katadyn) require more treatment time for colder, cloudy water than for warmer, clearer water.

Does anyone have experience with solar water disinfection - SODIS? 
Water should be exposed for 6 hours in PET bottles at sunlight - UVA - which 
has the same effect as Steripen, only cheaper and no batteries. 

I think that it is maybe not very practical to carry water for 6 hours on 
top of the backpack, horizontally, but I am interested anyway if someone 
tried this method, maybe as backup?
