A method and an apparatus for mixing discrete, microscopic portions of a gas (oxygen) in a liquid (water), wherein the liquid is brought into contact with a liquid repellent side of a microporous membrane, and the gas is contacted with the other side. The membrane, which may be a bundle of hollow fibers, has effective pore pathway diameters generally in the range 0.01 to 5µm, and the liquid pressure is regulated not to exceed that of the gas or to cause liquid to pass through the membrane. Gas/liquid mixed in this manner is conveyed and delivered in a low-liquid-turbulence incurring manner to avoid the discrete, microscopic gas portions from combining and provide them with a long retention time in the liquid.
