Do your own experiment removing alcohol

It takes a substantial amount of alcohol to remove water from gasoline.

Fortunately, in the US, there's not a lot of water in gasoline. And alcohol doesn't remove any of it, but combines with it so it's not an issue in engines. But I'm led to believe you shouldn't drink the water in Mexico.

But if purified water is used to minimize total dissolved solids it leaves virtually no contamination after the water is purged.

"Purified" implies nothing about TDS. Distilled or deionized water is free from minerals so can dissolve them.

Then the so-called de-alcoholed water is passed through a RAcor water separator filter with the "S" series 1 micron filter element.

Uh, what? Alcohol and water are miscible. A "filter", especially one which is based on particulate size ("one micron"), or which which separates based on specific gravity ("RAcor", sic) won't do a thing. Perhaps you should get a De-alcohol-orizer.
