Extracción de Polifenoles de la Cáscara de Citrus Sinensis para la elaboración de un coagulante natural en el tratamiento de Aguas Residuales

Abstract

The effectiveness of a natural coagulant based on orange peels (Citrus Sinensis) was evaluated in the treatment of domestic wastewater, for which the extraction of the phenolic compounds present in the peels was carried out through the Soxhlet method, and carried out tests in the jar test, whose results obtained in domestic wastewater treated with 3 ml of natural coagulant were: pH 6.83, BOD5 38 mg/l, COD 65 g/l, Total coliforms 1.8 NMP/100ml, color 66 UPC, turbidity 25 NTU, Total Suspended Solids 34 mg/l. The values in the untreated domestic wastewater of the same parameters were pH 7.47 BOD5 75 mg/l, COD 147 g/l, Total coliforms 28000000 NMP/100ml, color 80 UPC, turbidity 50 NTU, Total Suspended Solids 43 mg/l, when comparing results, we observed that the natural coagulant is really effective in the treatment of domestic wastewater.
