The U.S. Army Corps of Engineers, Savannah District has released results of tests of the dissolved oxygen (DO) injection system for the Savannah harbor deepening project.
According to the Corps, the tests of the DO injection system prove that the multi-million-dollar apparatus successfully mitigates for the reduction in DO in the Savannah River due to the current deepening project.
USACE Savannah District office stated the two-location system can place the required average of 40,000 pounds a day of pure oxygen into the river, according to a recently published report. The pure oxygen dissolves completely in raw river water, and then gets discharged back into the bottom of the river. Diffusers deep under the surface ensure the super-oxygenated water mixes well horizontally and vertically, with virtually no oxygen lost from the water surface into the atmosphere.
