 Typically in industry, alcohol and water are separated to a degree via DISTILLATION. The degree of separation depends on a number of factors such as the exact alcohol, the distillation apparatus, and control of the apparatus. 

If you are referring to ethanol (grain alcohol - the alcohol found in adult beverages), you can separate a mixture of ethanol and water via fractional distillation to the azeotrope of the mixture. About 96% ethanol and water. Further ordinary fractional distillation will not increase the % of ethanol. To further separate the ETOH/H2O mix, to approximately 100% ethanol, you must use a different process such as molecular sieves.
