- Performance of a Series of Polishing Ponds in the Treatment of Sanitary Sewage* Adriana Barbosa Sales de Magalhães Rafael Kopschitz Xavier Bastos Iván Andrés Sánchez Ortiz Marcos Alves de Magalhães Ingeniería Water quality pollutant removal stabilization ponds sanitary effluent treatment 5 The main objective of this research was to evaluate the functioning of a system of polishing ponds on a pilot scale in the post-treatment of urban sewage discharged from an up-flow anaerobic sludge blanket reactor and followed by a submerged aerated filter. The following variables were analyzed: transparency, temperature, dissolved oxygen (DO), pH, alkalinity, biochemical oxygen demand (BOD), chemical oxygen demand (COD), total Kjeldahl nitrogen (TKN), ammonia (NH3), organic nitrogen, nitrate (N-NO3), total phosphorus (TP), orthophosphate (PO4 3-), total suspended solids (TSS) and chloro- phyll-a. In addition, the planktonic communities were also identified and quantified. During the study period, the pond system registered the following mean and standard deviation of the removal efficiencies: 32.9±31.7% of BOD, 26.5±33.9% of COD, and 29.0±49.6% of TSS; good performance was observed in the removal of nitrogen compounds, and the following results were obtained: 58.4±28.1%, 87.5±15.4%, 24.4±42.6%, and 9.4±51.8%, respectively for TKN, NH3, organic nitrogen, and N-NO3; and 26.9±25.8 of TP and 34.3±32.7% of PO4 3-. During the research period, the planktonic community was represented by the following classes: Chlorophyceae, Euglenophyceae, Cyanobacteria, Cryptophyceae, Zygnemaphyceae, Chrysophyceae, and Dinophyceae; concurrently, the zooplankton registered low densities and was represented by the Rotiferous, Copepod, and Cladocera groups. The results help us understand the performance of polishing ponds in treating sanitary effluents. 2023 artículo científico 0124-8170 https://www.redalyc.org/articulo.oa?id=91175903008 https://www.redalyc.org/journal/911/91175903008/ https://www.redalyc.org/journal/911/91175903008/html/ https://www.redalyc.org/journal/911/91175903008/91175903008.epub https://www.redalyc.org/journal/911/91175903008/movil https://doi.org/10.18359/rcin.6636 en http://www.redalyc.org/revista.oa?id=911 Ciencia e Ingeniería Neogranadina application/pdf Universidad Militar Nueva Granada Ciencia e Ingeniería Neogranadina (Colombia) Num.1 Vol.33
