The average concentration of BOD, SS, TKN and T-P of influent were 94.81, 105.58, 9.72㎎/L, respectively. Also, these average concentration of effluent were 7.94, 2.98, 18.21 and 4.95㎎/L, respectively. The corresponding removal efficiencies were 91.33% in BOD, 97.18% in SS, 67.30% in TKN and 49.0% in T-P. The process of this system was maintained stably because of flowing by gravity. The media used for this study was Yakult filter with specific surface area of 130㎡/㎥ and surface loading rate of 28㎡/㎥. In this system, the removal efficiencies of SS and sludge were higher than those of activated sludge process. Twenty eight senora and sixty eight species of aerobic bacteria were identified from floating water and Yakult filters in the septic tank. Especially, only two strains of the bacteria were found from the effluent. Alcaligenes, Corynebacterium, Flavobacterium, Pseudomonas, and Staphylococcus of the bacteria were found, and they were known as excellent bacteria for the degradation of organic matter. Also, Alcaligenes, Bacillus, Flavobacterium, Micrococcus, Proteus and Pseudomonas, which can denitrification organic matter, were found and phosphorus removal bacteria, Acinetobacter was identified.
