Abstract

The advanced wastewater treatment plant of leather industry was selected to evaluated with its effluent water quality and statistical characteristics. Most of pollutants removal efficiencies were over 90% as well. And 95% reliability of effluent concentration were 106.8 mg/L of $COD_{mn}$, 72.04 mg/L of TN. However Effluent quality of TN exceeds the regulated limit. The range of coefficient of variation (CV) were between 0.18 and 2.49. Also, coefficient of reliability (COR) were between $0.03(BOD_5){\sim}0.63(COD_{mn})$ and 0.43 in terms of T-N, $Z_{l-a}$(Normalized Percentiles) value were 55.7 and 2.25 in terms of $BOD_5$ and T-N as shown in the following table.
