Do you have a lack of treatment capacity in your lagoon or activated sludge process? Dealing with high BOD? Feeling like expansion is your only option? Let us show you ECOFIXE, a solution for your problem.

THE ECOFIXE SYSTEM
The ECOFIXE system is a modular fixed-bed media biological wastewater treatment system that intensifies the treatment of aerated ponds and other biological reactors including SBR, activated sludge and oxidation ditch. The ECOFIXE modules can be used to augment an existing lagoon or bioreactor. They can also be integrated in the design of a new aerated pond allowing the dimensions of the structure to be reduced fourfold. In both cases, they are installed directly in the aerated basin where treatment intensification is desired. The fixed-bed media provide extensive surface area for the beneficial microbes to settle and thrive, and are more easily retained when fixed to a surface. This attached-growth biomass will prevent washout, treat more BOD and contribute less sludge than suspended growth free-floating bacteria. The treatment capacity is upgraded without needing to upgrade biosolids management.

ADVANTAGES OF THE ECOFIXE SYSTEM
• 20-40% lower cost than similar technologies (such as MBBR) for the same treatment
capacity increase
• Easy upgrade for existing lagoons or bioreactors, minimizes footprint for new design;
• No additional land or construction required;
• Fast and simple assembly and installation – typically within a week;
• Modularity allows for phasing;
• Sturdy;
• Energy efficient;
• No chemicals;
• Operational simplicity = low operating cost;
• Treats 100% of the flow with stable and constant performance;
• Reduces clarifier loading, no sludge increase.

THE ECOFIXE TECHNOLOGY
Each module contains a stainless-steel enclosure, equipped with a flotation system which is anchored to the bank of an aerated pond or the base of a reactor. The enclosure contains fixed media on which the fixed film biomass develops, treating the wastewater. The media is composed of polyethylene (partially recycled) and contains a UV inhibitor in order to preserve its integrity. Four fine-bubble aerators under each module ensure maximum oxygen transfer to the biomass and prevent development of preferential pathways within the modules. A simple cleaning protocol is done every 4-6 weeks: 2/3 of aerators are turned off; the increased pressure in the remaining 1/3 cleans the media. This is then rotated to the other 2/3. The ECOFIXE system crosses the aerated pond over its entire width (flat bottom) creating a permeable dam where 100% of the flow of the pond is treated. The modules can be installed between existing aerators (no infrastructure change required) and can be installed without stopping operations of the WWTP. The modules do not interfere with sludge removal operations which can be done with the ECOFIXE modules in place. The intensified treatment extends SRT without increasing sludge, so there will be no increase in clarifier loading or sludge removal requirements. The ECOFIXE system is self-sufficient and does not require an operator to be present.
