The analysis of the samples collected from the wastewater treatment plant showed that the recycled supernatant had a pH of 7.16~8.21, a conductivity of 371.1~769.1 μmho/cm, a total dissolved solid of 193.3~399.9 mg/L, and a turbidity of 0.901~54.3 NTU. The suspended solids of the recycled supernatant was found to be 0.4~45.6 mg/L, lower than the standard value in the Effluent Standards (50 mg/L). The ammonia nitrogen (NH3-N) and the Total Organic Carbon of the recycled supernatant were found to be 0.06~1.5 mg/L and 1.533~17.437 mg/L, respectively. The analysis of the Chemical Oxygen Demand of the wastewater treatment plant showed a concentration of 12.1~128.5 mg/L in the sample of the recycled supernatant.
