1. Small Tank Volumes -Needless to divide with anoxic tank and oxic tank -Independent of high loading rate(rapid response) 2. Low Operating Cost -Low DO conc.(DO below 0.2-0.6 mg/L) -No internal recycle -Reduce external Carbon source 3. Simple Upgrade -Upgrade is possible with only NADH Sensor 4. Easy Maintenance -Easy pH control(Recovery of alkalinity by denitrification) 5. Online Monitoring -Rapid system control and few manual adjustments 6. Increased Pollutional Load -High organic loading rate and short HRT; Ansan STP (385000 m3 per day) etc.
