Technical Advantages
No small openings (capable of handling raw wastewater without clogging).
No pressurization means significantly lower operating costs than pressurized systems (Comparison Chart) and no potential for effervescence and consequential air locking of pumps or pipes.
No pure oxygen headspace (and associated explosion potential).
No bubbles or micro-bubbles.
No moving parts except for side stream pump.
ECO2 System Design
Electricity Consumption Over 10 Years ($)
Based on 1 ton/day oxygenation system, Power cost $0.10/kWhr
Wastewater
H2S before and after SuperOxygenation
With D.O. present, the H2S in the head space is readily reduced to non-detectable levels (< 1 ppm) as confirmed in multiple field installations using superoxygenation of force mains. This advantage of superoxygenation can also be applied upstream of headworks and for primary clarifier odor control.
Consistently better results in H2S reduction than traditional odor control chemicals.
Significantly lower operating costs than traditional chemicals *(as low as 20-50%).
Flow-paced O2 feed system guarantees efficient use of O2.
No storing and handling of hazardous chemicals.
No chemical deliveries.
No increase in sludge production.
Clean Water
ECO2 adds already dissolved oxygen to the water.
Liquid-to-liquid mixing allows for faster & broader horizontal distribution of D.O.
Effective creation of an “aerobic cap” above the sediment.
O2 feed rate can be precisely controlled.
No bubbles – means no mixing of the vertical water column.
No destratification maintains cold water fish habitat.
Natural look of lake surface can be maintained, no obstacles for watercraft.
Robust system can be turned off as needed without danger of clogging delivery pipes or diffusers.
