1. get two full beers per helper
2. fill five gallon bucket and have someone start to stir, somewhat fast
3. Use dropper to start adding chemical to bucket slowly, a little goes a long way
4. Add drops until you start to see small snow flake things appear.
5. Now take turns as you drink the first beer with adding a slow stir to the bucket
6. At end of first beer stop stir and drink second beer as the bucket settles out
7. Filter the clear water and throw the settled sludge back out to the river
8. If repeating omit beer for each for the good of the group.
This is the basic procedure that all conventional water plants in Colorado use for water treatment. I would call your friendly water operator and see if you might get some of this chemical, and a tour of where your water comes from. They buy it by the truck load and all you need is 100 ml for a 28 day trip if using four gal per day. I am trying to talk a supplier into selling to the rafting community but no luck yet.
In wine there is truth
In beer there is strength
In water there is bacteria
