A method and apparatus for mixing discrete, microscopic portions of a gas (e.g. oxygen) in a liquid (e.g. water), wherein the liquid is brought into contact with a liquid repellant 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 of 0.01 to 5 mu m, 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 proved them with a long retention time in the liquid. |
