RE: FOOD GRADE
The correct word is "potable". As in you can put it in your cooking pot.
Your not saying how much you need wwtp2014, but these guys sell a lot.

RE: FOOD GRADE
However, if you want potable water grade chemicals (Drinking Water Treatment Chemicals), you can spend a little more and get NSF60 approved grade for potable water.
See the link. You may also contact the manufacturers directly.

The same manufacturers sell the "food grade" quality chemicals as well.

RE: FOOD GRADE
If you look up Food Chemicals Codex (FCC) on Worldcat, you probably will be able to find one in a library near you.
