    • Principle of FNR technology
    • Bio-reaction process arrangement composed of anoxic tank, aerobic tank, and ferrous electrolytic device.
    • Removal of organic matters and nitrogen by biological nitrification / denitrification through anoxic and aerobic processes.
    • Sewage treatment technology to remove phosphorus by ferrous ions generated from the ferrous electrolytic tank.
    • Principle of FNR construction method
    • It is a video of FNR which is the sewage treatment technology.
    • Principle of nitrogen removal
    • Principle of phosphorus removal
    • Features of technology (Advantages and appropriateness of technology)
    • Flow water is directly used as an organic carbon source required for denitrification (MLE process)
    • Proactively responding to T-P to strengthen the standards for water quality of effluents
    • Excellent efficiency of T-P removal regardless of load variations of water quality and changes of temperature
    • Minimization of scale generation on the cathode surface by applying an electrode switching method
    • The electrolysis reaction does not affect the growth of nitrifying microorganisms.
    • Replacement cycle of ferrous electrode : 2 ~ 3 years
    • Existing contact oxidation tank → Anoxic tank, improvement of aerobic tank process, no additional land
    • More excellent efficiency of nitrogen removal than the process with anaerobic process
