I remember when I had to do this for school a couple years back. Take a look at this. It's kind of your idea.

Basically, you use the sand/gravel/sieve to filter off the big particulates.

To clear up the water, u might use the cheesecloth or activated charcoal(not found in nature but effective).

If all else fails, manually centrifuge it :D.
