Treatment of industrial wastewater containing high concentration of ammonia was studied using biofilm media such as Bio-CAP^(TM), Bio-PO.P^(TM) and Ringlace. Among the various configurations of biofilm media process, Bio-CAP^(TM)-Bio-POP^(TM) media process was considered as the best process for organic removal and nitrification reaction. Volumetric organic removal and nitrification rate of this process approached to approximately 6㎏ COD/㎥/day and 800g NH₃,-N/㎥/day, respectively. Settler was located between Bio-CAP^(TM) and Bio-POP^(TM) reactor to remove the inhibitory effect of SS on nitrification in 2nd Bio-POP^(TM) reactor. Organic removal rate and nitrification rate of Bio-CAP^(TM)-Bio-POP^(TM) process were 5 and 4 times higher, respectively than those of general activated sludge process. By using Bio-CAP^(TM)-Bio-POP^(TM) media process, it was expected to decrease the required area for treatment of industrial wastewater containing high concentration of organics and ammonia.
