Industrial Wastewater Treatment
ECO2 offers an elegant solution to meet industrial wastewater discharge limits for BOD, Dissolved Oxygen (D.O.), and Hydrogen Sulfide. The efficient use of pure oxygen is often the most effective solution at the lowest ongoing cost.
Paper Mills
High strength process and wastewater from pulp and paper mills often contains high levels of BOD and sulfides, causing odors and requiring high D.O. levels for wastewater treatment. The ECO2 SuperOxygenation Technology provides an efficient means to add dissolved oxygen to process water, primary clarifiers and treatment lagoons.

Food & Beverage Industry
The food and beverage industry often deals with high strength wastewater that requires pretreatment and / or odor control. The ECO2 SuperOxygenation Technology can effectively add targeted amounts of dissolved oxygen to industrial wastewater to oxidize sulfides and high levels of BOD.
Oil Sulfide
Oil and gas wells often yield water during the extraction of the oil and gas from a reservoir, often with water often being the major constituent of the extracted liquid/gas volume. The extracting company goes to great length to separate the valuable oils and gases from this mixed liquid and gas stream. Once the products (oil, natural gas) are separated, the oil producer then must determine what to do with the remaining water.
This produced water is commonly laden with compounds that pose challenges to disposal. Typically, the oil producer has 3 options: re-inject the water into the oil/gas reservoir, inject the water into a disposal well, or discharge the water to surface runoff or other treatment facility. In many parts of the world, a surface discharge is preferable as the water can then be used for irrigation and/or livestock and wildlife use. Adding dissolved oxygen to the produced water can remove many undesirable contaminants and make the produced water safer and cleaner for surface discharge.
Power Industry
Warm cooling water from the power industry holds less oxygen, having a negative impact on the receiving water body. With an ECO2 SuperOxygenation System water can be enriched with higher levels of dissolved oxygen.
Landfill Leachate
High BOD, H2S, and high ammonia content can be reduced using oxygen before discharge to a municipal sewer system. Aerobic landfills can benefit through introducing additional D.O. to the leachate to supplement the bioreactor.
