An Initial Approach to the Presence of Pharmaceuticals in Wastewater from Hospitals in Colombia and Their Environmental Risk
Serna-Galvis, Efraim A.; Botero-Coy, Ana Maria; Rosero-Moreano, Milton; Lee, Judy; Hernandez, Felix; Torres-Palma, Ricardo A. MDPI (2022-03-18)Hospital wastewater (HWW) from three different cities in Colombia was characterized. Wastewater quality indicators and 38 relevant pharmaceuticals were examined. The HWW had pH from 6.82 to 8.06, chemical oxygen demand ... -
Application of catalytic ozonation using Y zeolite in the elimination of pharmaceuticals in effluents from municipal wastewater treatment plants
Prada Vásquez, Maria Angélica; Simarro Gimeno, Claudia; Vidal Barreiro, Isabel; Cardona-Gallo, Santiago-Alonso; Pitarch, Elena; Hernandez, Felix; Torres-Palma, Ricardo A.; chica, antonio; Navarro-Laboulais, Javier Elsevier (2024)Catalytic ozonation using faujasite-type Y zeolite with two different SiO2/Al2O3 molar ratios (60 and 12) was evaluated for the first time in the removal of 25 pharmaceutical compounds (PhCs) present in real effluents from ... -
Comparative degradation of two highly consumed antihypertensives in water by sonochemical process. Determination of the reaction zone, primary degradation products and theoretical calculations on the oxidative process
Serna-Galvis, Efraim A.; Isaza-Pineda, Laura; Moncayo-Lasso, Alejandro; Hernandez, Felix; Ibáñez, Maria; Torres-Palma, Ricardo A. Elsevier (2019)This work compares the sonochemical degradation of losartan and valsartan (antihypertensives) in water. Initially, the suitable operational conditions of ultrasonic power density and frequency were established. Under such ... -
Degradation of seventeen contaminants of emerging concern in municipal wastewater effluents by sonochemical advanced oxidation processes
Serna-Galvis, Efraim A.; Botero-Coy, Ana Maria; Martínez-Pachón, Diana; Moncayo-Lasso, Alejandro; Ibáñez, Maria; Hernandez, Felix; Torres-Palma, Ricardo A. Elsevier (2019)The simultaneous degradation of seventeen emerging concern pollutants in effluent from the municipal wastewater treatment plant (MWTP) of Bogotá-Colombia was studied using high frequency ultrasound (375 kHz). The considered ... -
Effective elimination of fifteen relevant pharmaceuticals in hospital wastewater from Colombia by combination of a biological system with a sonochemical process
Serna-Galvis, Efraim A.; Silva-Agredo, Javier; Botero-Coy, Ana Maria; Moncayo-Lasso, Alejandro; Hernandez, Felix; Torres-Palma, Ricardo A. Elsevier (2019)This work presents the treatment of selected emerging concern pharmaceuticals in real hospital wastewater (HWW) from Tumaco-Colombia by combination of a biological system with a sonochemical process. Fifteen compounds, ... -
