| Popis: | The purpose of this scientific work was to assess the performance of the system of wastewater treatment with trickling filter method (trickling filter) of urban waste water coming from the town of Skenderaj. Experiments done at the plant are made to evaluate the performance of aerobic filter and anaerobic systems for the removal of chemical oxygen demand (COD). The evaluation data trickling filter performance are generated under different experimental conditions. An average efficiency of COD reduction of 18 -30% is achieved in all concentrations of wastewater in a hydraulic loading of 5.5 m3/(m2∙d). Results lead to a design organic load of 0.96 kg COD/(m3 ∙ d) to reach a COD emissions in the range of 50-120 mg/L. As can be deduced from the results of this study, organic substances in the trajimit plant wastewater can be treated in a cost-effective and environmentally friendly using using trickling filters with plastic media. |
