The City of Fort Valley, GA is located near Macon, GA. The City operates a return-activated sludge, extended aeration wastewater treatment plant and discharges into Bay Creek, a small receiving creek. At lower flows, the plant operators are able to meet their stringent permit requirements but due to the arrangement of the plant, have trouble adding the required oxygen above 1.3 MGD of effluent flow.
The State of Georgia issued a new permit requiring the waste-water treatment plant to add up to 316 lbs of oxygen per day to the plant effluent. The City was faced with two options; 1) spend an additional ~ $2 million on tertiary treatment systems or reverse osmosis equipment to reduce the BOD to below 10 mg/L; or 2) offset the 10 mg/L of BOD and ammonia with dissolved oxygen (D.O).
The City chose ECO2’s SuperOxygenation technology to add the required amount of D.O. because of the low cost compared to tertiary treatment equipment and the high oxygen transfer efficiency. With the addition of the ECO2 system, the plant could operate reliably, and with little operator intervention to meet the net zero ultimate BOD discharge permit by offsetting the 10 mg/L of BOD and ammonia with D.O. for a net zero impact on Bay Creek.
Innovative and highly effective, SuperOxygenation technology is an eco friendly alternative to traditional chemical treatments for water and wastewater. Focusing on odor and corrosion prevention, ECO2 has helped cities across the country solve their needs in both municipal and industrial applications.
Become a leader in water treatment.
ECO2 SuperOxygenation systems for water and wastewater treatment are designed and produced by Eco-Oxygen Technologies, LLC headquartered in Indianapolis, Indiana. The technology is the pioneering effort of Dr. Richard Speece, Centennial Professor Emeritus of Civil and Environmental Engineering at Vanderbilt University.
The ECO2 oxygenation method is a simple process based upon the scientific principle of Henry’s Law. No chemicals and no moving parts other than standard industrial water pumps are used. The result is a robust, reliable, economically competitive and environmentally friendly technology.
In municipal applications, ECO2 technology eliminates hydrogen sulfide odor and corrosion by dissolving pure oxygen in wastewater at high concentrations (50-75 mg/l) which prevents the formation of hydrogen sulfide and the associated “rotten-egg” odor. This approach saves money on alternative chemicals, provides pretreatment and does not increase total dissolved solids. ECO2 engineers are presently focused on wastewater projects in Maine, Indiana, California, Kentucky and Texas.
