Innovative Technology Solutions

EDI continues to add new products and technologies through its Innovative Technology Series. In recent years EDI has added the “BABTM BIG BUBBLE MIXERS with Advanced Geyser Technology”, “INFINITETM Oxidation-Ditch for Tuned-Loop Bioreactors”, “FOXTAILTM Attached Growth Media”, etc. in this portfolio. EDI’s R&D and Engineering Department with its high caliber in-house engineers are always making new things and working on innovative technologies.

BAB Big Bubble Mixer

BABTM Big Bubble Mixers

Advanced Geyser Technology

BABTM technology is specifically engineered to be integrated with diffuser systems in biological process applications. EDI big bubble mixers use air from the same air supply as aeration diffusers simplifies the overall piping vs. those systems which need special air supply, special piping, and valve actuators or high-pressure compressors.

    FoxTail Media
    Attached Growth Media

    The EDI FoxTailTM attached growth media is deployed directly into a partial mix or complete mix lagoon. The process provides very large surface areas of media deployed in the lagoon and the bio growth surface area in conjunction with the advanced aeration technologies offered by EDI. Large FoxTail media areas located in the aerated zones of lagoons deliver enhanced C-BOD removals and can be engineered to offer high degrees of nitrification.
