The City of Barberton’s Wolf Creek Dam Intake Extension, Valve Replacement and Oxygenation System Project is intended to rehabilitate the existing Wolf Creek Dam Water Intake Structure and install oxygenation equipment in the reservoir.
The new oxygenation system is being installed to improve the raw water quality being transported to the water treatment plant. The hypolimnion of the Wolf Creek Reservoir exhibits anoxic conditions a majority of the time. This condition enables manganese to be taken up and transported in the dissolved form in the raw water. Manganese must be removed as it causes taste and odor complaints and staining of the plumbing fixtures. The final source water quality parameter of interest is total manganese. Quarterly averages in total manganese have been found to range from 0.092 mg/l to 0.168 mg/l. More importantly, manganese has been identified as a source of plugging the membrane filtration treatment system installed in the water treatment plant. Problematic times of the year are early spring and early fall when manganese can increase to concentrations over 0.200 mg/l for several weeks at a time, thus eliminating the option to run the membrane filters.
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.
