Eco Oxygen Technologies, ECO2

Eco Oxygen Technologies LLC, headquartered in Indianapolis, Indiana, develops and manufactures superoxygenation systems for water and wastewater treatment. The company's core technology is the Speece Cone, a submerged down-flow bubble contactor that dissolves pure oxygen into water under pressure to produce super-oxygenated water discharged through engineered diffusers—providing a chemical-free alternative to traditional treatment for hydrogen sulfide control, dissolved oxygen supplementation, and water body restoration. With over 20 years of superoxygenation installations, ECO2 offers systems for wastewater H2S prevention in collection lines, force mains, gravity sewers, headworks, and primary clarifiers; wastewater treatment optimization including industrial sulfide removal, supplemental dissolved oxygen, effluent DO and BOD offset, and in-river treatment; lake and river restoration through hypolimnetic oxygenation to reverse eutrophication and suppress algal blooms; and aquatic invasive species management using controlled CO2 delivery. Notable project references include the Savannah Harbor Expansion Project in Georgia for dissolved oxygen mitigation, San Pablo Reservoir in California for taste and odor compound reduction, Camanche Reservoir on the Mokelumne River for hypolimnetic oxygenation, and King County Sunset and Heathfield pump stations in Washington earning Envision Silver Award recognition. ECO2 provides complete system design services covering oxygen supply logistics, component specification, chemical cost comparisons, and sustainability metrics.
