How to make acetic acid more volatile so that it can be removed by vigorous aeration of an acetic acid-water mixture?
Aeration does not seem to be the way to go.
If there are no other ions in the water, electrolysis (Kolbe reaction) would convert the $\ce{HOAc}$ to ethane and carbon dioxide:
$$\ce{2CH3CO2^- -&gt; 2e^- + 2CO2 + H3C-CH3}$$
This process could probably be arranged to be done in a pipe with electrodes on the sides, so that the water was treated as it was used, rather than in a huge tank, where diffusion would slow down the completion of the reaction.
