Organic mass and nitrogen removal kinetic modeling in sequencing batch reactor

Organic mass and nitrogen removal kinetic modeling in sequencing batch reactor In this paper, the novelty consists of determining kinetic parameters for sequencing batch reactor (SBR)  operated for the experimental design Nº1 (ED-1) under single (oxic) and combined biological sequences in two phases (anaerobic-oxic) treating a Chemical Oxygen Demand (COD) influent around 5,466 mg/L. ED-2 comprised three phases (anoxic I-oxic-anoxic II) with the influent containing COD (1,119-1,598 mg L−1), NH4 +-N (63-94.5 mg L−1 and Total Kjeldahl Nitrogen (126 - 175 mg L−1). Kinetic parameters corresponded to the substrate maximum utilization rate r(m,S) and the half-saturation coefficient (K s) The r (m,COD) and K s was increased as the biological phases were increased from single oxic phase (−60 mg L−1 h−1; 2704 mg L−1), anaerobic-oxic phases (−100 mg L−1 h−1; 1,069.8 mg L−1) to the anoxic I –oxic-anoxic II phases (−250 mg L−1 h−1).

Abstract

In this paper, the novelty consists of determining kinetic parameters for sequencing batch reactor (SBR)  operated for the experimental design Nº1 (ED-1) under single (oxic) and combined biological sequences in two phases (anaerobic-oxic) treating a Chemical Oxygen Demand (COD) influent around 5,466 mg/L. ED-2 comprised three phases (anoxic I-oxic-anoxic II) with the influent containing COD (1,119-1,598 mg L−1), NH4 +-N (63-94.5 mg L−1 and Total Kjeldahl Nitrogen (126 - 175 mg L−1). Kinetic parameters corresponded to the substrate maximum utilization rate r(m,S) and the half-saturation coefficient (K s) The r (m,COD) and K s was increased as the biological phases were increased from single oxic phase (−60 mg L−1 h−1; 2704 mg L−1), anaerobic-oxic phases (−100 mg L−1 h−1; 1,069.8 mg L−1) to the anoxic I –oxic-anoxic II phases (−250 mg L−1 h−1). The kinetic coefficients were significant in the first anoxic and the oxic phases of SBR, for conventional and simultaneous nitrification-denitrification.
