Bubbles as a Means for the Deaeration of Water Bodies

Journal of Environmental Engineering, 2017
Occasional dissolved-air supersaturation - such as may occur, for instance, downstream of dams - is harmful to fish because it causes gas bubble disease. A counterintuitive but effective means of reducing dissolved air content is the injection of bubbles in the supersaturated water.
