Wastewater Treatment Processes

Supplemental Dissolved Oxygen

ECO₂‘s proven sidestream SuperOxygenation System can deliver readily dissolved oxygen where and when you need it.

Aeration Supplementation

Need to increase the capacity of your aeration basins without wanting to expand? The ECO₂ System can deliver more D.O. in the same space. The ECO₂ System has been proven effective in raw wastewater as well as in high MLSS concentrations. Its robust design with few moving parts and wide openings make it an excellent addition to any MBR, aerobic digester or conventional activated sludge process in need of an additional boost of D.O.

Convert Secondary Clarifier to Oxic Bioreactor

A unique solution for insufficient loading capacity, nutrient control, and floating sludge, by utilizing the tank volume of the existing clarifier for increasing aerobic (active) biomass. Superoxygenation is the only way to increase D.O. without disturbing the settling conditions in a clarifier.

4 Problems Solved with Oxic Clarifiers

Increased BOD removal (up to 66% with no additional tankage)
Improved nitrification in winter (increased aerobic biomass)
Improved stability for Bio-P (by increasing SRT & Reducing F:M)
Prevent rising sludge (due to denitrification in sludge blanket)

Wastewater Effluent D.O. Content & BOD Offset

Instantly boost D.O. without aerators or basins.

Post Aeration

Trouble meeting your D.O. discharge permit? The adaptable ECO₂ SuperOxygenation System can boost your effluent’s D.O. to any desired level. Whether it’s to meet a seasonal permit or to off-set effluent BOD and ammonia for a net-zero impact on the receiving water body.

Easily meet your D.O. Discharge Permit

ECO₂ has helped towns across the country comply with their D.O. discharge permits. Site or budget restrictions that don’t allow for the construction of re-aeration basins, the lack of sufficient elevation drop for step-aeration, or simply the need for higher D.O. levels for sensitive downstream waterbodies, are reasons for the implementation of a small footprint ECO₂ SuperOxygenation System.

Net-Zero Negative Impact

Off-setting BOD and ammonia with an increased amount of dissolved oxygen has helped one city receive a permit to build their WWTP and discharge into an impaired waterway with a net-zero negative impact.

The Kennebunk, ME Wastewater Treatment Plant discharges into a salmon stream. Their permit requires 8mg/L D.O. discharge, which they cannot achieve during the summer months. The ECO₂ System supplements the D.O. in the discharge and guarantees at least 8mg/L D. O.

In-River Treatment

Many of the world’s rivers are polluted and D.O. impaired. The ECO₂ SuperOxygenation Technology can effectively add high levels of dissolved oxygen to impaired waterways.

Deliver Large Amounts of D.O.

EDissolved 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.
