River, Harbor & Canal Water Quality Improvement
Delivering Pure Dissolved Oxygen Directly Where Its Needed
Deliver Large Amounts of D.O.
Dissolved Oxygen (D.O.) is good. Raising the D.O. in impaired waterways supports aquatic life and helps with the aerobic degradation of organic matter. Without the addition of dissolved oxygen lower depths of rivers are often void of oxygen, decreasing fish habitat and allowing for the accumulation of muck on the bottom. To support aquatic life in the D.O. impaired Savannah River during and after the dredging of the harbor, the US Army Corps of Engineers evaluated over 25 aeration and oxygenation technologies and chose ECO2‘s Speece Cones to do the job.
ECO2‘s Speece Cones can effectively deliver large amounts of dissolved oxygen from shore based, barge mounted or submerged systems to sensitive areas in polluted rivers.

The ECO2 “Speece Cone” Superoxygenation System was rated best of the 25 systems studied, based on cost, oxygenation level, flexibility and mobility.
NYDEP selected ECO2 for large-scale project to increase dissolved oxygen and improve water quality in the highly contaminated Gowanus Canal.
Water Quality Improvement Project in NYC’s Gowanus Canal
The ECO2 System was designed to continuously deliver dissolved oxygen to the Gowanus Canal during the 26 month construction period. The oxygenated water was distributed along a 2,500 ft diffuser pipeline to ensure adequate lateral mixing of the water without undue disturbance of bottom sediments.
