V. de et al. Can high rate algal ponds be used as post-treatment of UASB reactors to remove micropollutants? Chemosphere, v. 248, artigo 125969, 2020.

Acesso em: 10 jun. 2021.0045-6535http://www.repositorio.ufop.br/jspui/handle/123456789/14243The present study evaluated the removal capacity of a UASB-HRAP treatment system, combining anaerobic and microalgae-based, aerobic treatment, for eleven organic micropollutants present in raw sewage, including pharmaceuticals, estrogens and xenoestrogens. The UASB reactor and the HRAP were operated at a hydraulic retention time (HRT) of 7 h and 8 days, respectively. Influent and effluent samples from the UASB and HRAP were collected periodically. All the target compounds were detected in raw sewage, with an occurrence ranging from 70 to 100%. Removal rates in the UASB reactor were generally incomplete, ranging from no removal (25.12% for the hormone EE2-ethinylestradiol) to 84.91% (E2 - estradiol). However, the overall performance of the UASB þ HRAP system was highly efficient for the majority of the compounds, with removal rates ranging from 64.8% (ibuprofen) to 95% (estrone). Gemfibrozil and bisphenol A were the only exceptions, with overall removal rates of 39% and 43%, respectively. Hormones were the compounds with the highest removal rates in the system.en-USrestritoEndocrine disruptorsHigh rate algal pondsPharmaceuticalsSewageArtigo publicado em periodicohttps://www.sciencedirect.com/science/article/abs/pii/S0045653520301612https://doi.org/10.1016/j.chemosphere.2020.125969
