Intimate contact of water with a treatment gas is achieved by mixing the gas and water co-currently in a conduit containing static mixers, and directing the conduit into a gas contact apparatus that contains coaxial inner and outer tanks, the inner tank being open within, and shorter than, the outer tank, leaving a head space above the top of the inner tank. The conduit discharges the gas-water mixture at the base of the interior of the inner tank, permitting the water to flow upward through the annular space between the inner tank and the conduit, then over the weir formed by the open upper end of the inner tank and downward through the annular space between the inner and outer tanks. Gas is separated from the water at the head space, and treated degasified water leaves the apparatus at the base of the outer tank.
