It's probably a bit safer (easier to control) to use iodine which I carry for camping, even if only as backup. Once it's done it's thing, you can then put in some Vitamin C to neutralize most of the funny taste.

Water that has been disinfected with iodine is NOT recommended for pregnant women, people with thyroid problems, those with known hypersensitivity to iodine, or continuous use for more than a few weeks at a time.
