<p>A method and a system for enriching the oxygen content of a body of water having a relatively low oxygen content are disclosed. The method contemplates providing, in a pipeline communicating with the body of water, a pressurized, flowing aqueous liquid stream that is at a pressure greater than ambient and supersaturated with respective to the dissolved oxygen concentration thereof. The liquid stream is maintained substantially free of bubbles which grow in size under conditions existing in the body of water. The flow rate of the oxygen-enriched aqueous liquid stream is modulated so as to maintain a dimensionless number, defined as: <MATH> wherein rho = density of the pressurized aqueous liquid within the pipeline, D = internal diameter of the pipeline, V = mean liquid velocity of the pressurized aqueous liquid stream within the pipeline, gc = gravitational constant, DELTA P = pressure drop of the aqueous liquid stream flowing through the pipeline, L = length of the pipeline, and t = mean transit time required by the aqueous liquid stream to flow through the pipeline, at a value in the range of about l x l0<-><1><0> to about 5 x l0<-><7> until the stream is commingled with the body of water, the oxygen concentration of which is to be enriched.</p> |
