- Abstract
- This study aimed to obtain quantitative data for WWTP operators in phosphorus removal process. This was done by reviewing and comparing phosphorus removal efficiency(%), coagulants dosage(Al/P and Al2O3(mg/L)), sludge production(kg/㎥), and operation cost(won/㎥) of start-up and normal operation data. Phosphorus removal efficiency of all tertiary treatment process was up to 70 ~ 89 % in start-up and normal operation. Average molar ratio(Al/P) was similar as 5 in both operations, but average coagulants dosage (mg/L) of start-up (8.5 mg/L) was higher than normal operation (6.2 mg/L). Average operation cost was higher for start-up (33.6 won/㎥) than normal operation (28.4 won/㎥), while electricity cost was required for the normal operation (9.0 won/㎥) was higher by 3.5 won/㎥.
