Technical Bulletin No. 0197: Stream Reaeration Using Tonnage Oxygen
Re-aeration of streams is a subject which has long been of interest to the National Council and its members since some of the pioneering work was done by this organization as far back as 1945. Such re-aeration has been in practice at a relatively large number of mills where downstream hydropower stations are in existence and the turbines could be vented or impoundment discharge could be cascaded, so as to raise the dissolved oxygen content of the river. Since tonnage oxygen is rapidly becoming available at low cost in industrial areas, interest regarding its use for stream re-aeration has become aroused. Results of this work have been sufficiently encouraging to bear continuation of the studies.
