SHEP spotlight: DO system

SAVANNAH, Ga. – Contractors with CDM Constructors Inc. are finishing concrete placement for the intake structure on the downriver site of Dissolved Oxygen Injection System. The project is scheduled to be completed by the end of the year.

The system is one feature in the environmental mitigation for the Savannah Harbor Expansion Project.

As discussed previously on this blog, the DO system will force oxygen into river water via two separate plants using proprietary Speece cones to super-oxygenate water taken from the river and re-introduce it back into the river. The system is designed to provide 40,000 pounds of oxygen per day into the estuary to mitigate for the effects on dissolved oxygen from the harbor deepening.

Here’s a small scale version of how the system operates:
