APONTE-REYES, Alexander. Developing Ecological Models on Carbon and Nitrogen in Secondary Facultative Ponds. Ing. invest. y tecnol. [online]. 2014, vol.15, n.3, pp.437-456. ISSN 2594-0732.

Ecological models formulated for TOC, CO₂, y NH₄⁺, NO₃^- and NTK, based in literature reviewed and field work were obtained monitoring three facultative secondary stabilization ponds, FSSP, pilots: conventional pond, CP, baffled pond, BP, and baffled-meshed pond, BMP. Models were sensitive to flow inlet, solar radiation, pH and oxygen content; the sensitive parameters in Carbon Model were K_{COT Ba}, u_{max Ba}, u_{max A1}, K_1OX, V_A1, R1D_CH4, YB_h. The sensitive parameters in the Nitrogen model were K_{COT Ba}, u_{max Ba}, u_{max A1}, V_A1, K_OPH, K_OPA, r_4An. The test t-paired showed a good simulating of Carbon model refers to TOC in FSSP; on the other side, the Nitrogen model showed a good simulating of NH₄⁺. Different topological models modify ecosystem ecology forcing different transformation pathways of Nitrogen; equal transformations of the Carbon BMP topology could be achieved using lower volumes, however, a calibration for a new model would be required. Carbon and Nitrogen models developed could be coupled to hydrodynamics models for better modeling of FSSP.
