| Abstract | The removal of turbidity, chemical oxygen demanand (COD), ammonium and nitrate of Palm Oil Mill Effluent (POME) treated in a wastewater treatment plant was investigated in the present study. The Palm Oil Mill was located in the province of Esmeraldas-Ecuador. The treated POME was purified in a laboratory system consisting of a sand biofilter where physical-mechanical (turbidity removal), biological aerobic (removal of organic matter and nitrification) and anoxic (denitrification) processes took place. The purification system involved a sand biofilter that discharged into a vessel where water was recirculated to the biofilter. The hydraulic residence time in the system was 20 days (13.3 days in the biofilter and 6.7 days in the recirculation vessel). The removal of organic matter and nitrification was achieved by aeration (8 hours per day), while denitrification occurred during the anoxic period (16 hours per day). The system was operated for 294 days and reached 96% removal of turbidity, 92% of COD, 90% of ammonium and 9% of nitrate. |
