PCT No. PCT/EP92/02924 Sec. 371 Date Jun. 20, 1994 Sec. 102(e) Date Jun. 20, 1994 PCT Filed Dec. 16, 1992 PCT Pub. No. WO93/13022 PCT Pub. Date Jul. 8, 1993.The invention relates to a method of introducing hydrogen into aqueous liquids without forming bubbles. In this case, the introduction of the gas takes place through a composite membrane with a non-porous coating on the liquid side. Preferred fields of use relate to the charging of hydrogen into biologically or catalytically operating processes for the removal of oxygen, nitrite and/or nitrate from water.
