The present invention relates to a process for producing ultra-pure water, an apparatus for producing said ultra-pure water and a process for using the ultra-pure water produced according to said process. More particularly, the present invention relates to a process for producing ultra-pure water which comprises boiling a raw water to vaporize off the volatile components from the raw water, subsequently generating steam from the water, contacting the steam with a hydrophobic, porous, gas-permeable and liquid-impermeable membrane to make the steam permeate the membrane, and then condensing the steam, as well as to an apparatus for producing said ultra-pure water and a process for using said ultra-pure water.

A process for producing ultra-pure water which comprises boiling raw water to vaporize off volatile components from the raw water, subsequently generating steam from the boiled water from which said volatile components have previously been removed, contacting the steam with a hydrophobic, porous, gas-permeable and liquid-impermeable membrane to make the steam permeate the membrane and removing liquid mist sufficient to produce a high purity steam substantially free of impurities, and then condensing the steam to form ultra-pure water.
