Default Filtration of Water

I am planning a backpacking trip to Iceland, and was reading about glacial silt found in the rivers and streams over there and was thinking of a water filtration system that does to rely on any type of pump/ and or cartridges. I really don't want to lug around a water filter pump no matter how small or light it is.
Are there any types of filtration fabric perhaps?, as I am not worried about bacteria/viruses at all whatsoever.
Some type of cloth?
Thanks

Not exactly what you are looking for but these things are very small and effective at dealing with silt.

You could probably gravity feed through them just fine and that would meet your requirement to avoid any pumps.

As for trying to avoid any cartridges... if the cartridge only weighs 30 grams then is it really any different than carrying around a fabric?

coffee filters are popular silt-removers.

If you go the coffee filter route, you may find that you want to use a plastic filter cone to prevent the filter from ripping.

As an aside, are there fewer risks of bacteria/viruses in surface water in Iceland or is it just your personal preference to not treat water?

Glacial silt is very fine, in the micron range, while coffee filters filter particles in the tens of micron range.

In the 1930s the Mundays used their socks to filter glacial runoff. How big are the pores in socks?

It doesn't take everything out, but a coffee filter does take a fair bit out. You can usually notice a visual difference just with a bandana.
Obviously if you want to remove every last bit of rock flour, you're going to have to use a serious mechanical filter.

I've had great success using the coffee filters to remove glacial silt. Sometimes I have had to resort to using two filters at one time to get the most of it. If there is any left, I consider it "fiber".

We faced a similar issue on the Green River in Utah. The river is quite silted and the water will quickly clog most filters. Since we were in a canoe we ended up carrying enough water for five days in 50 litre containers. The only alternative, workable solution that was suggested by the veteran river travellers was to fill containers with water and leave then overnight for the silt to settle out....have you talked to anyone else who has done a similar trip in Iceland??

You wont even see the glacial silt in the water. Take an eye dropper of household bleach. Put two drops per liter of clear water, 3 drops if the water is cloudy and four drops if it is swamp water. Let it stand twenty minutes and it will be safe to drink. Much lighter and easier than dealing with a filter.
