Objectives: The purpose of this experiment was to illuminate the relationship between the phosphorus removal
rate of unit operation and the phosphorus removal rate of phosphorus volume loading in the Ferrous Nutrient
Removal process, which consists of an anoxic basin, oxic basin, and iron precipitation apparatus.
Methods: This study was conducted in order to improve the effect of nitrogen and phosphorus removal in domestic
wastewater using the FNR (Ferrous Nutrient Removal) process which features an iron precipitation reactor in
anoxic and oxic basins. The average concentration of TN and TP was analyzed in a pilot plant (50 m3/day).
Results: The removal rate of T-N and T-P were 66.5% and 92.8%, respectively. The NH3-N concentration of
effluent was 2.62 mg/l with nitrification in the oxic basin even though the influent was 17.7 mg/l. The NO3-N
concentration of effluent was 5.83 mg/l through nitrification in oxic basin even though the influent and anoxic
basin were 0.82 mg/l and 1.00 mg/l, respectively. The specific nitrification of the oxic basin (mg.NH3-N
removed/gMLVSSd) was 16.5 and specific de-nitrification (mg.NO3-Nremoved/gMLVSSd) was 90.8. The T-P
removal rate was higher in the oxic basin as T-P of influent was consumed at a rate of 56.3% in the anoxic basin
but at 90.3% in the oxic basin. The TP removal rate (mg.TP/g.MLSS.d) ranged from 2.01 to 4.67 (3.06) as the
volume loading of T-P was increased,
Conclusions: The test results showed that the electrolysis of iron is an effective method of phosphorus removal.
Regardless of the temperature and organic matter content of the influent, the quality of phosphorus in the treated
water was both relatively stable and high due to the high removal efficiency. Nitrogen removal efficiency was
66.5% because organic matter from the influent serves as a carbon source in the anoxic basin.
