  • Title: Nutrient removal from low strength domestic wastewater in sequencing batch biofilm reactor.
    Author: Altinbas U.
    Journal: Water Sci Technol; 2001; 44(1):181-6. PubMed ID: 11496671.
    Abstract:
    Nutrient removal was investigated in a packed bed column, which was operated by changing of aerated and non-aerated periods. Good removal efficiencies for nitrogen and phosphorus were obtained at long aeration period. Highest nitrification efficiency was observed in run3 because the aeration period was enough to allow nitrification. NO3 concentration was not significantly changed during the cycle, because of simultaneous denitrification during aerobic stage. Nitrogen and phosphorus removal efficiencies reached to 71 and 74% in run3 respectively. Effluent concentrations of TKN, Tot.P, NH4 and NO3 were found as 3.8, 3, 1 and 2.5 mg/l respectively.
