High efficiency water distribution plate design for enhanced oxygen transfer

A method of performing high efficiency oxygenation using a low head oxygenator system including one or more chambers, one or more distribution plates disposed over one or more corresponding chambers, a container disposed over the one or more distribution plates, and a gas input into each of the one or more chambers, the method comprising:

• providing a liquid in the container, such that the liquid flows through orifices in the one or more distribution plates into the one or more chambers, each of the one or more distribution plates having a predetermined number of orifices distributed within one or more zones of the respective distribution plate and no orifices in at least one remaining zone of the respective distribution plate;
• and
• providing a gas through the gas input to each of the one or more chambers, causing the gas to flow through a head-space portion of each of the one or more chambers, above a liquid stored in the one or more chambers,
• wherein the liquid flowing through the orifices in the one or more distribution plates creates jets that come in contact with the gas in the head-space portion of the respective chamber and then enter the liquid held within the respective chamber at regions disposed directly below the one or more zones of the corresponding distribution plate having the orifices, to create one or more circulation cells of bubbles in the liquid held within the respective chamber.
