EDI Aeration System
The IDEAL Bioreactor has the advantage of being outfitted with EDI’s high-efficiency fine bubble FlexAir® diffusers. The aeration technology applied to the IDEAL combines an operator-centric focus with almost four decades of advancement. EDI heavy-duty floating laterals or fixed-grid piping stand up to any environmental condition and allow easy access, even if the cell is covered. EDI diffusers provide the optimum combination of aeration efficiency and mixing performance that are crucial in a lagoon environment.
EDI’s patented BioReef BioCurtain incorporates multiple chains of BioReef that act as a biologically activated hydraulic curtain. The BioCurtain incorporates fixed-film technology to increase biomass in the reactor and provide contact stabilization during the settling and decant phases; it acts as a hydraulic buffer to address short-circuiting potential within the reactor and provides additional nitrification capability below 8 degrees C.
EDI-engineered decanters control effluent flow from the IDEAL Bioreactor. The decanter reduces moving parts and reduces operator involvement. The IDEAL decanter is engineered to minimize head loss between the IDEAL and partial mix lagoon, a crucial feature when upgrading an existing lagoon system.
Other data acquisition and reporting needs, to provide maximum energy efficiency and total nitrogen removal.
Front-of-Plant Ammonia Removal
Removing ammonia at the front of the plant provides several benefits. Other processes look to the back of the plant for ammonia removal where BOD concentration is lowest. The IDEAL process removes BOD and ammonia up front where warm, carbon-rich influent water is available to increase biological activity and denitrify for easy recovery of oxygen and alkalinity.
Nitrate and Total Nitrogen Removal
Total nitrogen and nitrate restrictions are on the horizon. Converting ammonia to nitrate is only the first step. Denitrification, or removing nitrate, is the second step necessary for total nitrogen removal. The IDEAL process provides this benefit as a natural function of the process, whereas many other systems require expensive upgrades to achieve similar results.
Long-Term Compliance Planning
Upgrades for advanced system control and maximum pollutant removal are made simple. No modification to the core treatment process is necessary for expansion of performance.
Energy and Chemical Savings
Microbes use nitrate in the same way they use oxygen. Denitrification that occurs naturally in the IDEAL process reduces oxygen requirements and provides decreased operational energy cost. The alkalinity recovered during denitrification can decrease or eliminate the need for chemical addition that is needed in some plants so complete nitrification can occur.
Worry-Free Operation During and After Peak-Plus Flow Events
The IDEAL process has shown an excellent ability to maintain performance during and after heavy water surges. The IDEAL process also adjusts easily to varying degrees of organic loading. All process control options incorporate “storm mode.” This mode of operation initiates during extremely high flow events to eliminate the potential of reactor washout. The IDEAL Bioreactor automatically resumes normal sequencing once flow decreases.
Minimum Operator Attention
The IDEAL process offers simple operation with operator commitment similar to traditional aerated lagoons.
