Secondary effluent from the wastewater treatment plant was
monitored for eight months, from May 2001 to January 2002, as
summarized in Table 2. Alkalinity, pH, and DO were measured on a
daily basis for evaluating nitrification and denitrification. Also, other
parameters such as TN, NH4–N, NO2–N, and NO3–N were measured
two or three times per week to calculate nitrogen removal. All the
