how long does it take to purify after putting it in the water?

Once it is completely dissolved, therefore that time may vary.

What is the shelf life of a sealed bottle?

Should be expiration date on bottle/box. I have never opened mine, just keeping it for emergency evacuation. Nope, I looked all over bottle and box, and no expiration date. I would use as long as kept sealed, in box and dark, dry place. O/w contact manufacturer Cochlans. I'm sure they have a website.

How many gallons of water can this product treat (purify)?

This product under ideal conditions will treat 6+ gallons of water according to Coghlan's instructions.
