We are heading for a trek in the Fann mountains and I've heard a lot of the water there is cloudy with very fine silt particles in it. I noticed most water filter manuals explicitly tell you not to filter water with silt. Presumably, silt clogs them very quickly. On the other hand those filters are usually designed to filter bacteria and other biological contaminants from water and thus are probably finer than I need, since we plan to use chemicals/boiling for water purification.
I also understand that filtration doesn't need to be perfect as the silt poses little actual health risk - we just want the water to not taste terribly.
So, given that I need to filter physical contaminants and not biological contaminants, what is my best option? Obviously I would prefer the gear to be light and cheap :-)
My best current bet is to use aeropress, as the filtration paper for it is light and cheap so we can bring a lot of it and just discard it when it clogs. We've also thought about some flocculation/coagulation chemistry, but none of what I've found seems to be safe to use with drinking water.
