The method for dissolving oxygen into water comprises of diffusing oxygen in small fine bubbles at the bottom of the water column in a closed vessel (101), building headspace pressure above the water column in the vessel, and circulating the oxygen from the headspace continuously till the desired oxygen dissolved concentrate of water is obtained. The apparatus for dissolving oxygen into water, comprises of an enclosed vessel (101), porous metallic diffusers (102), an agitator, a rotating hollow-shaft (103) extending till the bottom end of the water column, ventury slot (105) on the hollow-shaft configured to stay above the water level, and a disc (106) at the bottom end of the rotary hollow-shaft (103).
