Overall, facultative lagoon systems are simple to operate, but only partially reliable in performance. BOD 5 removal can range up to 95 percent. However, the TSS range may exceed 150 mg/L. Removal of ammonia nitrogen can be significant (up to 80 percent), depending on temperature, pH, and detention time in the system. However, the removal
