A floating fine-bubble aeration system for dissolving a gas in a liquid in which the system is floated. A grid of uniformly spaced fine-bubble diffusers is used to establish large area of bubble-laden liquid, having a substantially uniform density. The uniform density prevents the formation of any upwardly directed currents within the interior portion of the area. Bubble residence time is maximized, due to the absence of the currents, thus increasing the efficiency of dissolving the gas in the liquid.

1. Apparatus for aerating liquid held in a containment structure, comprisinga gas distribution means defining at least one input aperture and a plurality of output apertures for receiving, conveying, and outputting a supplied gas; a plurality of fine-bubble producing means, equal in number to the number of output apertures, in communication with the output apertures, for receiving a gas, forming fine bubbles of the gas, and discharging the fine bubbles into a liquid held in a containment structure within which said fine-bubble producing means are submerged, said fine-bubble producing means being configured to discharge the bubbles substantially in a plane; a floatation means, independent from said gas distribution means and said fine-bubble producing means, for maintaining said fine-bubble producing means substantially in a horizontal plane and submerged at a selected depth below a top surface of the held liquid when said gas distribution means and said fine-bubble producing means are placed in the held liquid, absent vertical support from the containment structure.
