It is added to prevent drinking, usually because what it is added to is highly toxic, and there are other agents (eg quinine) that will also make a substance bitter.
If you mean remove, distillation is the obvious choice but it might take a couple runs. Ion exchange resins may also be useful if they are compatible with the ethanol. Activated carbon would probably also work. Still, I would not advise ingesting any denatured alcohol unless it was chemically identified as pure and not laced with methanol - which will kill you or make you blind.

These substances are very different.
